Overview

PyMca

This is the MIT version of the PyMca XRF Toolkit. Please read the LICENSE file for details.

Installation

Ready-to-use packages are available for the most common platforms.

PyMca frozen binaries for MacOS and Windows can be obtained from Sourceforge

Unofficial Debian packages are also available, but you should check if official pacakges are available for your distribution.

Please continue reading if you want to use PyMca with your existing Python installation.

The simplest solution is to use pip:

pip install PyMca5

You can add the usual --user qualifier to install only for your local user rather than system-wide:

pip install PyMca5 --user

If you want to build from the source distribution or from a git repository checkout, you may want to have Cython installed on your system.

Examples of source installation

In your default system-wide python installation, run one or the other of the two (not both) commands below (may require root/administrator access):

# Run one of the following (not both); pip is preferred
python setup.py install    # use python setuptools
pip install .              # use the pip package manager

Or, to install just in your local user account:

# Run one of the following (not both); pip is preferred
python setup.py install --user   # use python setuptool
pip install . --user               # use the pip package manager

You will need the following dependencies installed:

python (3.6 or higher recommended)
numpy
fisx
h5py

If you want to use the graphical interface provided, you will need a running python installation with one of the following combinations:

PyQt5 + matplotlib (PyMca license will be GPL unless you have a commercial PyQt5 license)
PySide2 + matplotlib (PyMca license will be MIT because PySide2 is LGPL)

If you want to embed PyMca in your own graphical applications, I recommend you to use the McaAdvancedFit.py module. It is very easy to embed.

Testing

To run the tests after installation run:

python -m PyMca5.tests.TestAll

Development Plans

Use the fisx library for all Physics calculations and not just for corrections.
Compound fitting.

If you have any questions or comments (or contributions!), please feel free to contact me or submit a pull request.

Enjoy,

[debian] 5.5.0 problem with tests

Hello armando,

while preparing the Debian package, I got this error. it seems that pymca tests mandata an X connection now.

Batchfit hdf5
The main purpose of this PR is to homogenize batch fitting and fast fitting in terms of output. Most interesting additions are .h5 output and saving of diagnostics (e.g. fit residuals). Apologies for the extensive refactoring.

Comparing GUI for batch and fast fit that provides identical output (in terms of structure):

Changes from a user perspective:

optional output formats like for fast-fitting (most importantly .h5) .csv and .tif are disabled for multiprocessing because merging hasn't been implemented for those

.edf output results in a single multi-image (like in fast-fitting) OutputBuffer has the option to save single-image edf's but this is not exposed by the GUI

concentrations.txt file is only saved when fit files are saved

Some comments on implementation:

Both batch fitting and fast fitting now share the same OutputBuffer (class that takes care of memory allocation and saving)

McaAdvancedFitBatch._processList seems to support multiple non-HDF5 stacks but judging from McaAdvancedFitBatch.__processStack this cannot work I think

The fit configuration is saved in .h5. However only one configuration can be saved while McaAdvancedFitBatch supports multiple configurations.

PyMcaBatch has been refactored (e.g. to support bootstrap). This has only been tested on win32 and debian (non-frozen). Binaries on Mac seem to pass only roifit options, seems strange.

McaAdvancedFitBatch has an _obsolete parameter to preserve the way data was saved before (testing purposes, currently disabled). Keep it or remove?

The files McaAdvancedFitBatch and PyMcaBacth contain several TODO's which indicate some doubts I have on existing functionality (not introduced by this PR).

bunch of files with no licenses header and copyright owner

Hello Armando,

I am preparing the pymca5 package. So once again Ineed to do the license check. Since I will create new binary package

python3-pymca5 etc... this package will be reviewed by the ftpmaster team. They are using this tool also to check for non free files.

So could you fix all these files. This will ease the review at the end.

thanks

Frederic

[debian] please use setuptools requires in order to provide the build dependencies

Hello,

In order to build pymca and run the tests during the build, I needed to add all these dependencies. It is possible to automatically generate the Debian binary dependency from the setup.py (like for pyFAI or silx). It would be great if you could provide this for pymca.

Then I could maintain a patch on top of this for Debian, in order to deal with the pyqt5 (dependency). I am not sure thaht pyqt5 provide eggs infor for this purpose.

I got these informations looking at the autodoc sphinx part during the build.

Cheers

Windows build lacks HDF5 SWMR support

Hi Armando,

We have noticed that we cannot open our NXS files that were produced in SWMR mode with the currently available Windows build of PyMca. Since it works fine on our Linux systems which have access to HDF5 1.10.0, I guess the Windows build contains HDF5 1.8.x?

Thanks for looking into this,

Tom

Fix rounding within OmnicMap's getPositionFromIndexAndInfo
This PR aims to fix an intermittent issue in reading positions from maps.

@clsandt sent me a map where:

deltaX = 49.97058868408203

x0 = -815.0

x1 = 884.0

The number of jumps (intervals) in X is ((x1 - x0) / deltaX) which is 33.9999996946446, which means that the number of measurements nX is 33.9999996946446 + 1.

The old code wrongly rounded this down. This is what the consequences look like:

The new code rounds before converting to int so it is more robust to numeric inaccuracies. I think the change is self-explanatory. After the change (also as Omnic's software shows it):

The installation was without error messages and dependencies should be met. Any idea?

[IO] [HDF5][ROI Imaging] Offser subsampling when working with huge HDF5 files

Currently HDF5Stack1D proceeds to load dynamically the data if they do not fit into memory.

It would be convenient to offer the user the alternative to sub-sample the data.

Monitor and positions would have to be sub-sampled too.

Import from blissdata instead of bliss

The blissdata package is a much lighter dependency than bliss. It is available on pypi and anaconda.

# PyMca5/PyMcaCore/RedisTools.py

from bliss.config import get_sessions_list
from bliss.config.settings import scan as rdsscan
from bliss.data.node import get_node, get_nodes

# PyMca5/PyMcaCore/RedisTools.py

from bliss.config import get_sessions_list  # TODO
from blissdata.settings import scan as rdsscan
from blissdata.data.node import get_node, get_nodes

get_sessions_list is unfortunately not in blissdata. I'll try to make that happen.

FYI: soon blissdata will also work without gevent.

[HDF5] Change double-click behavior?
To access show info via the context menu seems counter-intuitive.

To change the behavior would imply:

Double-click as a short-cut to Show Information (equivalent to silx)

Single-click to show the context menu

Right-click unchanged (identical to context menu)

For datasets it seems fine, I am not so sure about groups.
