HI gmxusers,
i am using gromacs version 3.3.1
i am new to gromocs, i was taken protein.top file (which is generated by
pdb2gmx). In this file i have included ff.itp , popc.itp and lipid.itp but
protein atom types already there (generated by pdb2gmx). This .top file used
for inserting of protein into mebranes by using genbox. It was run without
problem, given .gro which contain both protein and popc and .top file . when
i have used this .top and .gro for energy minimisation it's showing that,
Fatal error:
Atom types NR, HC , CR1 not found
these type of atoms not there in .gro file but present in .top file .
Iam pasting the aminoacids which contain these type of atoms
