[gmx-users] Nucleic Acid in GROMOS54A7

[Souparno Adhikary]

Hi all,

I was trying to simulate a protein-DNA complex using gromos54a7 forcefield.
The error comes as,

Fatal error:
Residue 'DA' not found in residue topology database

Clearly, it is not finding the DA residue in its database. How can I solve
this?

Thanks,
