Package: lpa-xrd
Line Profile Analysis - X-Ray DiffractionThis project is related to the analysis of crystals containing dislocations by X-ray diffraction. It was developed and used for a study conducted during a research internship at the laboratory of material and structural sciences of theÉcole Nationale Supérieure des Mines de Saint-Étienne. This repository contains the distribution of one of the three published python packages that have been proposed to conduct line profile analyses based on simulation results:lpa-input(line profile analysis input generator)lpa-xrd(line profile analysis x-ray diffraction simulation program)lpa-output(line profile analysis output analyzer)The repositorylpa-workspacecontains the parameters and the scripts for the generation of the data used in the study. You can then easily replicate the results obtained or use it as inspiration to take the code in hand and conduct your own calculations. The software is placed in the public domain and you can use it as you wish. However, users are encouraged to contribute to the development and report issues.FeaturesThe packagelpa.xrdcan be used to:make a local copy of the X-ray diffraction simulator codeautomate the tasks of compilations and executionsInstallationThe package is indexed onPyPIand installable directly via pip:pipinstall-Ulpa-xrdExamplesOutput data files1.0.0 # v: lpa-xrd version

To become familiar with the use of these modules you should go through these scripts in the following order:test_code.pytest_run.pyIn the sources the docstrings are carefully written and it is recommended to refer to the documentation with thehelp()python command to list the available functions, classes and parameters.The installation from PyPI does not allow the modification of the code.
