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
