[gmx-users] Arbitrary S-S bonds

[Cesar Araujo]

Hi,

Can anybody tell me how can I generate arbitrary S-S bonds with gromacs? The problem is that I have a protein and I want to specify some S-S bond between two cysteine residues but they are not an options given by pdb2gmx -ss. Should I touch topology file by hand? Why pdb2gmx do not recognizes automatically SSBOND records in pdb files?

Regards,
César.-
