We have a basic hdf5 nexus-style (but not nexus) hdf5 format. The scanning positions are in length-N arrays, one for each axis, and the XRF spectra are stored in an array of shape (N, 4, M), where 4 is the number of channels on the xspre

Click on a scan to inspect it. PyMca has been developed by the Software Group of the European Synchrotron Radiation Facility . If you are in doubt about how to pronounce it, just think about how you would spell πMCA . For the end user, PyMca is a ready to use, and in many aspects state-of-the-art, set of applications implementing most of the needs of X-ray fluorescence data analysis.

PyMca tutorial. Our data are stored in files created by spec. The standard spec file format can be opened by PyMca. Run PyMca and open your data file (you may need to change the filter to see all of the files). Click on the mca tab and double click on a MCA spectra to plot it in the plot window. Click the logscale button above the plot window.

The Getting Started tutorial is a very old tutorial written by Darren Dale and initially tailored to CHESS users but usefull to everybody starting to use PyMca.

Introduction. This is a guide on how to use the program PyMCA for X-ray fluorescence (XRF) imaging analysis at the NanoMAX beamline. PyMCA is developed at ESRF by V. Armando Solé. It can be downloaded from SourceForge, as a standalone program for Windows or MAC. You can also install is as a python package if you are developing in python. 1.

You would be “compatible” with PyMca but you would be missing relevant information known at acquisition time like live_time and calibration parameters. The most versatile file format supported by PyMca is without doubt HDF5. You can find information about it at the HDF Group web site

The calibration measurement must have been done with the same conditions as your samples were measured; the same photon energy, incidence angle, exit angle, distance to detector, surrounding of the sample area, etc. Calibration should be measured right before or after the sample measurement. The CHARMed PyMca protocol calls for the calibration of standardless PyMca results using a specific, widely available set of high‐precision certified reference materials designed specifically for use with heritage copper alloys, the so‐called copper CHARM set (Heginbotham et al. 2015). would spell πMCA. For the end user, PyMca is a ready to use, and in many aspects state-of-the-art, set of applications implementing most of the needs of X-ray fluorescence data analysis.
