GenX Files

This package contains GenX 3.5 a program to refine x-ray and neutron reflectivity as well as surface x-ray diffraction using differential evolution. It can also serve as a general fitting program.

Changes 3.5.11
==============
 * Fix export of Table
 * Fix bumps statistics setting the error column of the parameter table
 * Add documentation for Norm FOM

Changes 3.5.10
==============
 * Add command line option to set the relative parameter variation beak condition
 * Fix an error that can happen when a numpy floating point error is raised in the windows version
 * Fix parameter addition in python API module

Changes 3.5.9
=============
 * Update sns_mr data loader to changes in reduced data format.

Changes 3.5.8
=============
 * Fix crash on Linux systems when automatically simulating, bug #189
 * Fix some with the snap that prevented loading SXRD plugin with 3D view
 * Snap now stable enough to use, but does not support multiprocessing due to access issues with confinement

Changes 3.5.7
=============
 * Online check for new GenX versions and option to download new setup file/in-place pip update
 * First version of snap binary distribution for Linux systems other than Ubuntu 18.04/20.04
 * Better copy to clipboard of selected parameters in error statistics dialog 

Changes 3.5.6
=============
 * Add option to edit the script in an external editor
 * Fix issue of GenX crashing if incompatible locals are specified in system configuration #187
 * Fix bug that caused script editing issues on some platforms #188

Changes 3.5.5
=============
 * Fix an issue with Reflectivity plugin instrument dialog causing
   silent fails to update an read values from after running Sim function.

Changes 3.5.4
=============
 * Add data loader for SINQ six text file format

Changes 3.5.3
=============
 * Fix bugs in handling of insertion/deletion of parameters
 * Fix bug in printing of plots and table
 * Fix query of ORSO database in SimpleReflectivity in some circumstances

Changes 3.5.2
=============
 * Add a new modeling option to spec_inhom model that allows automatic generation
   of neutron super-mirror structures from user defined Stack parameters.
 * Captuer model errors during fit that did not occure on first evaluation.

Changes 3.5.1
=============
 * Fix some issues with deleting and moving parameters in the grid that
   were caused by changes for undo/redo functionality.
 * Add (beta) support for ORSO SLD database for SimpleLayer and SimpleReflectivity
 * Some fixes in SimpleLayer plugin

Changes 3.5.0
=============
 * Add undo/redo functionality for most user actions as for changing the script or parameter values
 * History dialog that shows the undo actions and allows removal of previous steps while keeping later ones
 * Reorganize menus to make it more accessible
 * Improved sorting of parameters by object or parameter with grouping
 * Start logfile from GUI and show dialog with logged messages (Help menu)
 * Load multiple datasets from suitable data loaders (orso+xrdml)
 * Configure new reflectivity model from metadata read from .ort files (radiation, resolution etc.)
 * New option to automatically stop a fit when relative parameter spreads a reduced below a threashold value.
   Setting the parameter to e.g. 1% will stop once the parameter that varies the largest fraction of its fit
   range has a spread of less than 1% within the population. Seems very stable and is helpful for long-running
   fits with MPI that can't be stopped manually, well. (Thanks to Larry Anovitz for the idea.)
 * Major updates to the main tutorails in the documentation
 * Update orso .ort file format to use the new orsopy package with the updated specification
 * Fix update of Pars plot during fit when SimpleReflectivity plugin is loaded
 * Fix bumps fitting functionality and add update of Pars plot for this solver
 * Fix bug where fitting with multiprocessing without numba would fail
 * Fix in plotting of error bars to be below simulation
 * Fix incompatibility with matplotlib >=3.5.0
 * General refactoring for the GUI code to allow undo/redo functionality. May have introduced new bugs. As always
   All feedback is welcome.
 
Changes 3.4.12
==============
 * Limit matplotlib version for PyPI to <3.5.0 as this breaks some code within GenX
