i am running protein with ligand complex. i am following the methods given
by justin. i am using opls force field. i have converted the protein pdb
using pdb2gmx and ligand file using topolgen. after that i have
concatenated both in gro and include the lig.itp in topology file. while
performing the energy minimization i got the error, which is pasted below
Fatal error:
Syntax error - File forcefield.itp, line 18
Last line read:
'[ defaults ]'
