Hi Rob, 

Thank you for checking with your colleague.

I have been trying to use GUI on Linux through on my own workstation and also on HPC (through an interactive virtual desktop). I have encountered some errors for compatibility of versions that I am trying to fix. If you would think that running through GUI would give some information, I would record a journal file to see what is being called if this is the correct method to understand the processes. Then, I will share with you as soon as possible. 

Thank you.
