PyMca Files

Instead of the default download, you may find better suited downloads for your platform under the folder containing the latest release:

http://sourceforge.net/projects/pymca/files/pymca/PyMca5.9.7/


Notes:
See the changes section below for new features.

Tutorials can be found at:

http://pymca.sourceforge.net/documentation.html

Ready to use binaries for:

- Windows 64 bit: File pymca5.9.7-win64.exe

- MacOS X:  File PyMca5.9.7.dmg

For MacOS users, once the program installed, it might be necessary to execute from the terminal the command

sudo xattr -cr /Applications/PyMca.app

to be able to execute the program by double-clicking its icon. Alternatively it also works from the terminal by typing:

/Applications/PyMca.app/Contents/MacOS/PyMcaMain

Users of other platforms should either:

- Build from the source code.
- Use PyMca as supplied by your linux distribution.
- Install PyMca in a conda environment https://anaconda.org/conda-forge/pymca 

PyMca can also be installed from PyPI. For that just 'pip install pymca'

The mimimal dependencies are PyQt5 or PyQt6 or PySide6, numpy, fisx, h5py and matplotlib.

Changes:

VERSION 5.9.7
-------------
- GUI. Support dark mode.

- CLI. Common command line interface for all applications, with --help.

- GUI. Add the possibility to remove the default settings (File menu | pymca --clean_ini).

- HDF5. Refresh keeps the tree expansion and the selection, and updates the plots.

- HDF5. Add Auto REFRESH option to update the plotted data every second.

- HDF5. Add the possibility to plot signals against a right Y-axis and to select multiple monitors (right click on the table headers).

- HDF5. Allow scalar monitors.

- HDF5. Improved sorting of entries using several keys by priority (Correct sorting).

- HDF5. Prevent crashes when reading files being written. Closing a file releases it completely.

- HDF5. Do not plot misleading curves when selecting several entries with different counter or motor names in the AUTO tab.

- HDF5. Skip positioners that are not datasets (Motor Info plugin).

- HDF5. Compatibility with silx 3.1.

- HDF5. Show scan number and title of HDF5 scans as for SPEC files. Read H, K, L from the positioners if available.

- ROI Imaging. Integrate the Mask Scatter View plugin as scatter mode for maps with per point motor positions, like irregular or mosaic maps (requires silx).

- ROI Imaging. Validate the HDF5 stack selection with explanatory messages. Add "No 1D data" option to load stacks of images.

- ROI Imaging and RGB Correlator. Allow to open incomplete scans padding the missing points with NaN.

- ROI Imaging. Correct the reshaping of stacks with NaN values.

- ROI Imaging. Correct outdated titles in PCA and NNMA vector plots.

- 1d-Plots. Legend of the active curve uses the active curve color (black).

- GUI. Correct printing of plots with PyQt6 and PySide6.

- GUI. Compatibility with matplotlib 3.11. Require matplotlib 3.5 or newer.

- Compatibility with numpy 2.4.

- Packaging. Correct multiprocessing issues of frozen binaries.


VERSION 5.9.6
-------------

- Add support of Python 3.14

- Add compatibility with numpy 2.4.0

- API. McaTheory.setData limits priority: function arguments > configuration > full range

- XRF. Bug fix in batch processing when using fit files.

- GUI. Force light mode

VERSION 5.9.5
-------------

- Add the possibility to white NaN values in RGB Correlator.

- IO. Improved sorting of scans in HDF5 files.

- XRF. Add support for standard batch fitting of BCF files.

- XRF. Support three incoming beam filters.

- XRF. Support secondary excitation calculations fitting M subshells.

VERSION 5.9.4
-------------

- XRF. Allow to fit M subshells


VERSION 5.9.3
-------------

- Compatibility with numpy 2.0

- GUI. Compatibility with matplotlib 3.9.0

VERSION 5.9.2
-------------

- XRF. Prevent considering twice the same element when using the SingleLayerStrategy.

- Packaging. Compatibility with PyInstaller 6.x

- GUI. Improved PyQt6 compatibility.

- GUI. Compatibility with current silx master branch.

- GUI. Add histogram of pixel intensities to image views (requires silx).

VERSION 5.9.1
-------------

- ROI Imaging. It is now possible to apply NNMA on stacks of images.

- ROI Imaging. HDF5 stacks of images could not be selected due to a bug introduced in 5.8.2.

- MCA. Correct ID18 calibration issues.

VERSION 5.9.0
-------------

- IO. Compatibility with h5py 2.10 (Ubuntu 20.04)

- GUI. Compatibility with Matplotlib 3.8
