Hi, Leah-

There is still a dependency missing as part of your system's setup-- this is something your system administrators need to sort out.

In particular, the missing library is pointed out in this kind of error message in the system check:

suma: error while loading shared libraries: libGLw.so.1: cannot open shared object file: No such file or directory

... which means that a library called "mesa" is missing, I believe. (It is possible it comes as part of the "epel-release" dependency that we install on most systems, since I don't see an explicit library for that in the RedHat 7 installation instructions for AFNI.)

Can you ask your admin to install that package? It might be done with something like "sudo yum install -y mesa-libGLw", but I don't have a RedHat 7 system to test on at the moment...

Your administrators can run the "afni_system_check.py -check_all" just like you did, and see if the dependency is resolved.
