Dear Sir/Madam,
For orienting the protein and membrane, I have used the .mdp and
following topology file:

After running grompp to generate .tpr file I get following error:
Program grompp, VERSION 4.5.4
Source code file: gmxcpp.c, line: 248
Fatal error:
Topology include file gromos53a6_lipid.ff/forcefield.itp not found
But in the above topology file, if I change the
#include gromos53a6_lipid.ff/forcefield.itp line to *;*include
gromos53a6_lipid.ff/forcefield.itp
This file is not optional, so failing to include anything makes further
problems. You need such a file. You are doing something non-standard, so
your burden of following directions, and/or understanding how the
include file and force field mechanism works is a bit higher than normal :-)

I get following error:

Source code file: topio.c, line: 653
Fatal error:
Syntax error - File popc.itp, line 1
