Dear gromacs user,
I have a complex generated by docking calculation and I would perform a MD
by gromacs. I have a problem with ligand atoms. In the pdb file the ligand
appears as UNK and if I process this file in order to start simulation I
receive this messagge error:
"Residue 'UNK' not found in residue topology database"
this part of file concerning ligand and it is not a residue. In order to
fix this problem can I replace the UNK with another tag that is Known in
topology database for a ligand??? or How can I fix this error???
Thanks in advance for answers
