[gmx-users] Regarding defining termini in new rtp entry

[Tsjerk Wassenaar]

Hi Ilya,

If it is an amino acid, albeit modified, you can make pdb2gmx
recognize it as such by adding it to the file 'aminoacids.dat'. This
file is in the installation directory. You can also copy it to your
working directory and change it there, as it will then take precedence
over the other one. Do mind to increment the number at the top of the
file for every amino acid you add.

Hope it helps,

Tsjerk
