Dear Chen,
At the moment we do not have a distribution for RHEL. We recommend
that you get the debian packages for PROFisis and its dependencies and
concert that with the alien tool to an RPM package. That will allow a
smooth installation on RHEL.
You would probably want to look at this page:
https://rostlab.org/owiki/index.php/Packages
to learn which pakcages you will need and how to get them.
All the best,
Guy Yachdav
