[gmx-users] Loss of GTP in topology file.

[s lal badshah]

Hi,
I have added missing atoms to my pdb file through servers of WHATIF,when I use the force field option then the following output comes in shell console:
Fatal error:
Residue 'GTP' not found in residue topology database
and the following files are created:
 2a5f.top  2a5f_A.itp  2a5f_B.itp  posre_A.itp  posre_B.itp
Please guide me so that GTP is added to PDB.Further which force field and box will be better for my simulation of enzyme-Protein GTP complex?
regards,
