The structure of these files is completely unclear to me. I also didn't find
any explanation of the gromacs website. Is there a online explanation of the
format and how new entries can be added?
I retrieved all information on PTR from the PRODRG server. Isn't there some
way to directly copy and paste this information in the confuguration files?
Below the PTR info obtained from PRODRG
