• imagetool: add file selector for loading HDF5 files with chunking (5c5d53b)

  File dialogs in the imagetool manager now include an option to load HDF5 files with chunks="auto" using xarray’s open_dataarray function. This allows for efficient handling of large datasets by enabling lazy loading and chunking.

• imagetool: add normalize to view that adjusts color levels based on the currently visible data (7be78c6)

  Adds a new action to the right-click context menu of ImageTool image panels that adjusts the color levels to span the data values currently visible in the view, like AdjustCT in Igor Pro.

• manager: add more options to concat dialog (8473728)

  The concatenation dialog now allows users to specify keyword arguments to xarray.concat such as coords, compat, join, and combine_attrs. Also add a checkbox to remove original tools after concatenation.

• manager: display watched variable name in tool title (567e7cb)

  When creating an ImageTool for a watched variable, a label is added just like for data loaded from files. This makes it easier to identify which variable is being displayed.

• manager: add menu for Dask client management (aef4178)

  Adds a Dask menu to the main window, allowing users to connect to existing Dask

  clusters, create local clusters, and view client information.

• analysis.image: rewrite gaussian_filter to support dask (7d691d3)

• analysis.transform.rotate: rewrite rotate function to support dask (ea4ad00)

  The rotate function has been rewritten to support chunked inputs. The input array must not be chunked along the rotation axes.

• utils.array.trim_na: make trim_na work with dask (ec267b3)

• analysis.transform.shift: rewrite shift function to support dask (fec0cf1)

  The shift function has been rewritten to support chunked inputs.

• explorer: improve double click handling for directories and allow folders to be opened by plugins (e5d795f)

• explorer: correct file manager open command on Windows (0325010)

  Opening the current selection in the file manager on Windows was not working correctly due to an incorrect command format. This commit updates the command to use the proper syntax for selecting a file in Windows Explorer.

• manager: fix occasional failure to detect running manager instance (63319a1)

• ktool: correct unit for work function spinbox (384c4dc)

⚡️ Performance

• manager: chunk by default when loading workspace (4ee0a57)

• imagetool: faster data slicing for dask arrays (b215d2f)

  Optimizes performance by caching transposed graphs.

• kspace: do not allow dask rechunking for momentum conversion (d42132e)

  During momentum conversion, rechunking can lead to excessive memory usage and slow performance; therefore, rechunking has been disabled. Users should ensure that their input arrays are appropriately chunked or loaded into memory before performing momentum conversion operations.

• imagetool: avoid recomputing data when showing or hiding the colorbar (b5c27e0)

• imagetool: speed up initialization for dask arrays by optimizing global min/max calculation (b9b08f6)

• manager: add tooltips to link, dask, and watched var name icons (b43063f)

• imagetool: open in explorer if dropped files are folders (a2616fd)

  Previously, dropping folders into the imagetool would lead to an error message stating that files with extension ‘’ are not supported. This commit changes the behavior so that if all dropped items are folders, they will open in a new tab of the tabbed explorer instead.

• imagetool: reorder some menu items for better grouping (9cba0ac)

• manager: show tool indices in batch rename dialog (e05a923)

v3.15.1 (2025-10-29)

🐞 Bug Fixes

• io: make dataloader thread-safe (#185) (c31755c)

  Ensure that the dataloader methods function as expected in multithreaded contexts. Especially, current_loader and current_data_dir are now context variables, meaning that they are now safe under multiple threads setting different values.

• imagetool: make associated tool access thread-safe (6dcddf5)

• manager: include real variable name when copying code for watched variables (f6b6062)

• imagetool: fix wrong slot handling in PySide (c456b1f)

• io.plugins.erpes: fixes an issue where empty files would be cached when viewing info of DA maps in the data explorer (b328611)

• goldtool: better remaining time estimation (495202d)

⚡️ Performance

• imagetool: improve performance with dask arrays (9641043)

v3.15.0 (2025-10-18)

✨ Features

• imagetool: auto-compute small dask arrays (4b10312)

  When loading data into the imagetool, if the data is a dask array and its size is below a certain threshold (configurable via erlab.interactive.options["io/compute_threshold"] or the settings GUI), the data will be automatically computed into memory. Default threshold is 2048 MB.

  Additionally, adds a “Load Into Memory” action to the File menu in ImageTool only visible for chunked arrays which calls .compute() on the data when triggered.

• io.plugins.erpes: cache .zip files as HDF5 files for faster loading (412fdc4)

  When loading a .zip file, cache it as an .h5 file in a hidden cache directory. This speeds up subsequent loads of the same file. Also, DA maps are now always loaded as chunked (dask) arrays, improving scalability for large data.

• manager: show child tools (ff1f9b1)

  When opening analysis tools (e.g., dtool, ktool, …) from an imagetool in the manager, the child tools are now displayed in the manager as well. When saving and loading the workspace, the state of these child tools is also preserved.

  This change also enables the user to cherry-pick which tools to save when saving the workspace, or to load only a subset of tools from a saved workspace.

  Note that this change accompanies many changes across the whole interactive module under the hood. Although workspaces saved with older versions should still be loadable, workspaces saved with this version will not be loadable in older versions, with ambiguous error messages.

• interactive: add show_traceback utility function that displays error messages with highlighted tracebacks (6798f83)

• manager: enable reindexing tools (62b41a4)

  Adds a new action to reset all indices of ImageTools in the manager in the order they appear.

• manager: enhance integration with Jupyter notebooks (69ef2af)

  Adds a new magic command %watch to monitor and sync data between ImageTool manager and Jupyter notebooks. This feature allows users to easily update data in the notebook when changes are made in the ImageTool window and vice versa, facilitating a smoother workflow for data analysis and visualization.

  Also adds a new function, erlab.interactive.imagetool.manager.fetch which allows users to fetch a copy of the data in a specific ImageTool window in the manager by its index.

• utils.hashing: add utilities for hashing xarray DataArrays (#172) (4fc1f5f)

  Adds a new module that provides fingerprint_dataarray, a function to generate a unique fingerprint for xarray DataArrays. This is useful for quickly comparing data and checking for changes.

🐞 Bug Fixes

• io.plugins.maestro: fix concurrent access to cache dir (21f5df8)

• manager: update icons in menubar on system appearance change (eb357a3)

• io: make igor datatree backend compatible with xarray 2025.9.1 (8d8eab5)

• manager: improve compatibility with numpy <2.3 (9019613)

  Note that from this version, the ImageTool manager is no longer compatible with previous versions of erlab.

• io: suppress xarray warnings due to new defaults introduced in pydata/xarray#10062 (#175) (2f1cd64)

⚡️ Performance

• manager: micro-optimizations to file loading mechanism (be1c624)

• explorer: micro-optimization for data explorer rendering, might be effective on windows (0f6ef67)

♻️ Code Refactor

• imagetool: add icons for some menu actions and buttons (b232640)

• explicitly remove support for Qt5 (995c96b)

• io: use dask for parallel loading (081c706)

  This commit changes the parallel loading mechanism from joblib to dask. The parallel_kwargs attribute for loaders are now ignored. In order to configure parallel loading, users should set up the dask client accordingly.

• manager: allow using the Enter key (Return on macOS) to open selected items (83ef7bc)

• manager: set workspace file default extension to .itws to avoid confusion with regular HDF5 files (6455528)

• new ImageTool Manager icon for macOS (c15ce26)

• io.plugins.erpes: add new temperature sensors (b56f2b0)

• use pydantic for user configuration handling (#179) (252bf14)

  Changed the internal implementation of ImageTool user configuration handling, making future maintenance easier.

• utils.formatting: make some private formatting functions public (da28dd5)

v3.14.1 (2025-09-10)

🐞 Bug Fixes

• qsel: handle decreasing coordinates in width-based selection (#169) (cff0bed)

• imagetool: make ImageTool work with dask arrays (73f8ad6)

  Passing dask arrays to ImageTool used to load the entire array into memory. This commit fixes that by ensuring that the data is kept as a dask array and is indexed lazily. However, this makes the GUI much slower to respond, so it is recommended to use ImageTool with in-memory arrays when possible.

• improve autoscaling behavior for erlab.plotting.gradient_fill (fd065f2)

• utils: fixes uniform spacing check not applying tolerance (1ba2483)

⚡️ Performance

• speed up momentum conversion grid calculation (8da5bc0)

  Improves speed of k-space grid calculation using numexpr. Should also reduce memory usage during momentum conversion for large data.

• io.utils: deprecate wrapper functions for xarray I/O (a1d740b)

  Deprecates open_hdf5, load_hdf5, save_as_hdf5, and save_as_netcdf in favor of direct xarray methods. Use xarray.open_dataarray and xarray.DataArray.to_netcdf directly for better compatibility and performance.

v3.13.0 (2025-07-18)

✨ Features

• interactive.explorer: improve open in finder functionality (8571106)

  On macOS and windows, using the open in finder/explorer functionality now also highlights the selected file in the file manager instead of just opening the directory.

• interactive.explorer: add multiple tabs to data explorer (04bfcdf)

  The data explorer is now tabbed, allowing users to open and manage multiple directories simultaneously.

• interactive.utils: enhance IconButton to accept additional icon customization options (1dee58b)

• imagetool.manager: enhance data replacement logic (#153) (cf3005a)

  The replace argument for itool now supports negative indices to replace the newest ImageTool window, and allows for replacing the next index if it has not yet been created. For example, if you have 2 windows open (indices 0 and 1), you can use replace=-1 to replace the newest window (index 1) or replace=2 to create a new window if it does not exist yet.

• io.igor: add support for saving DataArrays to Igor Pro binary files (#152) (9207cde)

  • Implemented save_wave function in erlab.io.igor to save xarray DataArray objects as Igor Pro binary files (.ibw).

  • Adds a new dependency: igorwriter

🐞 Bug Fixes

• io.plugins.da30: use libarchive-c only if it is correctly installed (017685f)

  Improper installation of libarchive-c can lead to TypeError upon import. This change places the import of libarchive inside a try-except block to handle such cases gracefully, ensuring that the code falls back to using the built-in zipfile module if libarchive is not available or improperly installed.

• io: remove alias for da30 and improve documentation (ea5ae2b)

♻️ Code Refactor

• interactive.explorer: refactor into submodule (6313bbc)

• interactive.explorer: misc. edits for future improvements (a6113ca)

v3.12.1 (2025-07-04)

🐞 Bug Fixes

• io.plugins.merlin: take energy step from data attributes (84bc6b9)

  Fixed and swept mode scans have random numerical errors in the start & step of the energy axis. The error of the step accumulates over the scan, effectively resulting in a tiny renormalization of the energy axis. We choose to ignore the energy axis information contained in the wave, and take the step from the attributes instead.

♻️ Code Refactor

• io.plugins.merlin: do not subtract BL Energy from eV for Live XY and Live Polar scans (379fc8d)

  The BL Energy attribute is not reliable for Live XY and Live Polar scans, so we just take the raw energy values like Igor Pro does.

• Deprecated module erlab.interactive.utilities is removed. Use erlab.interactive.utils instead. (af2c81c)

• Deprecated module erlab.characterization is removed. Use erlab.io.characterization instead. (8d770bf)

• Deprecated module erlab.analysis.utils is removed. Use erlab.analysis.transform.shift and erlab.analysis.gold.correct_with_edge. (0b2ca44)

• Deprecated alias slice_along_path in erlab.analysis is removed. Call from erlab.analysis.interpolate instead. (305832b)

• Deprecated aliases correct_with_edge and quick_resolution in erlab.analysis are removed. Call from erlab.analysis.gold instead. (075eaf8)

• Removed deprecated aliases load_igor_ibw and load_igor_pxp. Use xarray.open_dataarray and xarray.open_dataset instead. (7f07ad2)

• The default attribute name for the sample temperature is changed to sample_temp from temp_sample. This will unfortunately break a lot of code that relies on the key temp_sample, but will be easy to refactor with find and replace. (32e1cd5)

• All dataloaders must now add a new keyword argument to load_single, but implementing it is not mandatory.

  Also, dataloaders that implements summary generation by overriding generate_summary must now switch to the new method.

  See the summary generation section in the updated user guide.

  Furthermore, the isummarize method is no longer public; code that uses this method should use summarize instead.

  The usecache argument to the summarize method is no longer available, and the cache will be updated whenever it is outdated. (0f5dab4)

  This commit adds a new data loader for beamline ID21 ESM at NSLS-II, Brookhaven National Laboratory.

• io.dataloader: add formatters (2ee9a4a)

  A new attribute named formatters and a new method get_formatted_attr_or_coord has been added to loaders. This allows custom per-attribute pretty-printing behavior.

• io: add parallel argument to load (88cd924)

• io: add xarray backend for igor files (1fe5ca5)

  .pxt, .pxp, and .ibw files can now be opened with xarray methods such as xr.open_dataset and xr.open_dataarray. See the updated user guide for more information.

🐞 Bug Fixes

• io.dataloader: properly reorder coordinates (3ebfb0f)

  Coordinate order was broken for loaders which assign coordinates in inherited post_process. This is now fixed, and returned data will be consistently ordered with respect to the mapping, with the dimension coordinates coming first.

• erlab.io.plugins.maestro: temporary fix for xarray issue (c2d04a3)

• io.plugins.da30: properly handle output types (6297aba)

  The DA30 loader now tries to return a dataset from .zip files only when there are no coordinate conflicts. In the case of conflicts, the loader will return a DataTree.

  Also, single region DA30 .pxt files will now return a DataArray consistent with the equivalent .ibw file.

• interactive.fermiedge: allow transposed input to fermi edge fitting tool (dcae75e)

• interactive.imagetool: retain attrs when exporting slice (1bed572)

  When accessing the data of a single slice from the right-click menu of ImageTool, the attributes of the original data are now kept. This allows saved slices or data opened in other tools to retain their attributes.

• resolve gui script not working on windows with conda (62253d0)

• io.plugins.merlin: combine ImageTool file menu into single entry (6e28ac2)

• io: add postprocessing and validation for DataTree objects (3fb3ff5)

• io: add warning when file is ambiguous (8daabb8)

• io: remove renaming steps from load_single in multi-file loaders (542f4f2)

  Combining before renaming coords should be more straightforward

• io: allow missing alpha coord (c9deed4)

  Validation checks will not warn about missing detector angle, allowing XPS measurements.

• io.dataloader: only allow real file or folder names as input (b9a59cc)

  The previous behavior allowed passing f_001.pxt to load f_001_S001.pxt, f_001_S002.pxt… but this was confusing since there is no file named f_001.pxt. This commit disallows such input.

• cleanup erplot namespace (007eedb)

• io: implement metaclass (e787b1c)

  Whenever the identify() method failed to find any files, subclasses had to explicitly raise FileNotFoundError. This resulted in a lot of boilerplate code and ambiguous error messages. Now, all subclasses can just return None in identify() when no files are found. The appropriate error is automatically raised.

• io.igor: raise OSError on load fail (6c7a4c4)

• move dataloader cell formatting implementation to utils module (0f2cb1c)

• io: deprecate calling igor functions from top level namespace (bb8af7c)

  Calling erlab.io.load_wave and erlab.io.load_experiment is deprecated. When writing new code, use xarray.load_dataarray and xarray.load_dataset instead.

• utils.array: add new functiontrim_na (c628b5b)

  This function trims the edges of DataArrays where all values are NaN.

• accessors.kspace: add method argument (204073e)

  Momentum conversion through the convert() method of the kspace accessor now supports an additional keyword argument method that can be used to choose different interpolation methods supported by scipy.interpolate.RegularGridInterpolator. Note that methods other than 'linear' will take much longer to execute.

• analysis.interpolate: add solver args (24be3b0)

  FastInterpolator now supports solver and solver_args keyword arguments introduced in scipy 1.13.0.

• interactive.colors: implement BetterColorBarItem limit editor (7dd1477)

  The interactive tools goldtool and dtool are now directly accessible from the right-click menu of 2D images in ImageTool.

• accessors.general: add option to qsel.around to disable averaging (5aaed85)

• plotting.general: add NonUniformImage functionality to plot_array (86d8c1a)

  plot_array can now plot data with unevenly spaced coordinates. It uses matplotlib.image.NonUniformImage with the default interpolation option set to ‘nearest’. The resulting plot may be different from xarray.DataArray.plot which uses pcolormesh to generate image plots.

• interactive.imagetool: add copy limits to colorbar menu (29c37c4)

  Right-clicking on the colorbar will now show a menu which contains a button that copies the current color limits to the clipboard. This is useful when manually adjusting color limits.

  Three functions that were directly accesible from the erlab.analysis namespace are now deprecated. Import them from their respective modules.

• remove deprecated module analysis.utilities (8b79ab5)

• analysis.image: add check for NaN in input (095554f)

  Derivative functions now check for NaNs in input data and raise a warning.

  The interactive derivative tool automatically fills NaNs in the input data with zeros and shows a warning message.

• remove unpacking inside np.r_ (6c27864)

• improve initial import time (f720973)

v2.8.5 (2024-07-31)

🐞 Bug Fixes

• plotting.annotations: properly pass keyword arguments in mark_points_outside (2136939)

• plotting.annotations: expose property label generation to public api (545781d)

  A new property_labels function can be used to generate strings that are used by label_subplot_properties so that the labels can be used as titles easily through eplt.set_titles. Also, label generation now recognizes time, given as ‘t’ with default unit seconds.

v2.8.4 (2024-07-26)

🐞 Bug Fixes

• erlab.plotting.general: improve plot_array keyword versatility (1dc41cd)

  Enables additional kwargs with valid data dimensions as the key to be passed onto qsel.

  Accessors in utils.py has been moved to general.py, so that utils.py only contains utilities for creating accessors.

• improve type annotations (b242f44)

v2.8.3 (2024-07-08)

🐞 Bug Fixes

• interactive.imagetool: various fixes related to manager (3d3f55e)

  This fix incorporates many changes to the ImageTool and ImageTool Manager.

  First, the archiving function of the manager now works properly, and tries to clear memory eagerly.

  When opening data from a file using the GUI, the name of the file will now be displayed in the title bar of the ImageTool. This file name is also propagated to the name displayed in the manager.

  Furthermore, the archiving and show/hide functionality of the manager has been updated to restore the window geometry automatically. When the user shows or unarchives a hidden or archived window, the previous position of the window is restored.

  Some icons and the layout of the manager has been modified, and tooltips has been added to the buttons.

  Also, some unexpected behavior regarding linking has been resolved.

• plotting.plot3d: temporarily disable broken monkey patch (220f23f)

• replace broken signature for dynamic functions (39a3954)

  Use pickle to save and load files instead of erlab.io.load_hdf5 and erlab.io.save_as_hdf5.

v2.8.0 (2024-06-17)

✨ Features

• erlab.io.plugins.ssrl52: changes to loader (512a89b)

  The loader now promotes all attributes that varies during the scan to coordinates. Also, if the energy axis is given in kinetic energy and the work function is inferrable from the data attributes, the energy values are automatically converted to binding energy. This may require changes to existing code. This commit also includes a fix for hv-dependent swept cuts.

• erlab.io.dataloader: reorder output coordinates (178edd2)

  Coordinates on the loaded data will now respect the order given in name_map and additional_coords, improving readability.

• interactive.imagetool: add ImageTool window manager (b52d249)

  Start the manager with the cli command itool-manager. While running, all calls to erlab.interactive.imagetool.itool will make the ImageTool open in a separate process. The behavior can be controlled with a new keyword argument, use_manager.

• interactive.imagetool: add undo and redo (e7e8213)

  Adjustments made in ImageTool can now be undone with Ctrl+Z. Virtually all actions except window size change and splitter position change should be undoable. Up to 1000 recent actions are stored in memory.

• interactive.imagetool: remember last used loader for each tool (eb0cd2f)

🐞 Bug Fixes

• interactive.imagetool: fix code generation behaviour for non-uniform coordinates (3652a21)

♻️ Code Refactor

v2.7.1 (2024-06-14)

🐞 Bug Fixes

• interactive.imagetool: Integrate data loaders to imagetool (7e7ea25)

  A new property called file_dialog_methods can be set in each loader which determines the method and name that is used in the file chooser window in imagetool.

• accessors.kspace: hv_to_kz now accepts iterables (36770d7)

v2.7.0 (2024-06-09)

✨ Features

✨ Features

• interactive.imagetool: add bin amount label to binning controls (7a7a692)

• add accessor for selecting around a point (aa24457)

• accessors.fit: add support for background models (550be2d)

  If one coordinate is given but there are two independent variables are present in the model, the second one will be treated as the data. This makes the accessor compatible with y-dependent background models, such as the Shirley background provided in lmfitxps.

• io: make the dataloader behavior more customizable (4824127)

  Now, a new average_attrs class attribute exists for attributes that would be averaged over multiple file scans. The current default just takes the attributes from the first file. This also works when you wish to demote a coordinate to an attribute while averaging over its values.

  For more fine-grained control of the resulting data attributes, a new method combine_attrs can be overridden to take care of attributes for scans over multiple files. The default behavior is to just use the attributes from the first file.

🐞 Bug Fixes

• plotting: make gradient_fill keep axis scaling (51507dd)

♻️ Code Refactor

• analysis.image: add check for 2D and uniform inputs (22bb02d)

• try to fix synced itool garbage collection (932cc5a)

  This only happens in GH actions, and it doesn’t happen every time so it’s hard to debug.

• create utils subpackage to host internal methods (3fa2873)

  The parallel module is now part of utils, without a compatibiliity layer or deprecation warning since nobody is using the functions from parallel anyway.

• add deprecation warnings for utilities (5d375b8)

  All submodules named utilities.py have been renamed to utils.py for consistency. The old call to utilities.py will still work but will raise a warning. The modules will be removed on 3.0 release.

• rename erlab.interactive.utilities to erlab.interactive.utils (d9f1fb0)

• rename erlab.analysis.utilities to erlab.analysis.utils (ed81b62)

v2.5.0 (2024-05-13)

✨ Features

• extended interactive accessor (f6f19ab)

  The qshow accessor has been updated so that it calls hvplot (if installed) for data not supported by ImageTool.

  Also, the qshow accessor has been introduced to Datasets. For valid fit result datasets produced by the modelfit accessor, calling qshow will now show an hvplot-based interactive visualization of the fit result.

• itool: make itool accept Datasets (f77b699)

  When a Dataset is passed to itool, each data variable will be shown in a separate ImageTool window.

• analysis.image: add multidimensional Savitzky-Golay filter (131b32d)

✨ Features

• imagetool: add method to update only the values (ca40fe4)

• add interpolation along a path (7366ec4)

  The slice_along_path function has been added to analysis.interpolate, which enables easy interpolation along a evenly spaced path that is specified by its vertices and step size. The path can have an arbitrary number of dimensions and points.

🐞 Bug Fixes

• io: remove direct display call in interactive summary (d44b3a5)

  This was causing duplicated plots.

• plotting: add some validation checks to plot_array (2e0753c)

  The functions plot_array and plot_array_2d now checks if the input array coordinates are uniformly spaced. If they are not, a warning is issued and the user is informed that the plot may not be accurate.

• plotting: increase default colorbar size (3208399)

  The default width argument to nice_colorbar is changed to 8 points. This ensures visibility in subplots, especially when constrained layout is used.

• delay interactive imports until called (ad15910)

• This change disables the use of guess_fit. All fitting must be performed in the syntax recommended by lmfit. Addition of a accessor or a convenience function for coordinate-aware fitting is planned in the next release. (59163d5)

✨ Features

• itool: add copy code to PlotItem vb menu (7b4f30a)

  For each plot in imagetool, a new ‘copy selection code’ button has been added to the right-click menu that copies the code that can slice the data to recreate the data shown in the plot.

• add 2D curvature, finally closes #14 (7fe95ff)

• plotting: add N argument to plot_array_2d (2cd79f7)

• add scaled laplace (079e1d2)

• add gaussian filter and laplacian (8628d33)

• add derivative module with minimum gradient implementation (e0eabde)

• fit: directly base models on lmfit.Model (59163d5)

🐞 Bug Fixes

• dynamic: properly broadcast xarray input (2f6672f)

• fit.functions: polynomial function now works for xarray input (3eb80de)

• analysis.image: remove critical typo (fb7de0f)

• analysis.image: dtype safety of cfunc (b4f9b17)

• set autodownsample off for colorbar (256bf2d)

• disable itool downsample (e626bba)

⚡️ Performance

• itool: add explicit signatures to fastbinning (62e1d51)

  Speedup initial binning by providing explicit signatures.

♻️ Code Refactor

• fit: unify dynamic function names (20d784c)

• update dtool to use new functions (a6e46bb)

• analysis.image: add documentation and reorder functions (340665d)

• rename module to image and add citation (b74a654)

• dtool: cleanup unused code (f4abd34)
