Hello all

I am new for gromacs. I have to do MD simulation of membrane protein docked with
organic molecule.
I have gerated top and itp for ligand using PRODRG server also generated top
file for complex.
But when I am generating .tpr file for a POPC system using grompp getting an error:

creating statusfile for 1 node...
checking input for internal consistency...
calling /lib/cpp...
processing topology...
Cleaning up temporary file gromppWQnjOb
Fatal error: Bond atom type names can't be single digits.

I am using gromacs-4.5.5

Can someone help me to find out where is actually problem is occuring?

With regards
