GenX is a versatile program using the differential evolution algorithm for fitting, primarily, X-ray and neutron reflectivity data, lately also surface x-ray diffraction data. The differential evolution algorithm is a robust optimization method which avoids local minima but at same is a highly effective. GenX is written in python and uses the wxpython package for the Graphical User Interface (GUI) Screenshot. A model to fit is defined either through a GUI plug-in or via a python script. The possibility to script everything makes it easy to develop completely new fitting model. Clearly, GenX is extremely modular, making it possible to extend the program with models and plug-ins for most fitting problems.
At the present GenX is shipped with models for x-ray and neutron specular reflectivity, off-specular x-ray reflectivity and surface x-ray diffraction. A detailed description, of a older version, has been published in https://www.iucr.org/cgi-bin/paper?aj5091 .
Feedback and Help: You can find a manual with examples at https://aglavic.github.io/genx/doc/, for reflectometry a good start is with the SimpleReflectivity guide https://aglavic.github.io/genx/doc/tutorials/simple_reflectivity.html and our Tutorial Videos https://aglavic.github.io/genx/doc/tutorials/neutron_fit.html.
Naturally a program does not become better if I do not get feedback from you! If you found a bug or want to have something included in the program submit a ticket on SourceForge at https://sourceforge.net/p/genx/tickets/ .
Thank you for your report. Information you provided will help us investigate further.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:
sudo yum install epel-release
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install genx, simply use the following command:
sudo snap install genx
Browse and find snaps from the convenience of your desktop using the snap store snap.
