Hi, Thanks for the reply. One thing, while giving the '-ff' flag it is asking for some string. So I renamed all my force field files as except spc.itp and ions.itp. Renamed files are .....
1) ffprot.atp 2) ffprot.rtp 3) ffprot.itp [ includes ffnonbonded.itp and ffbonded.itp ] pdb2gmx -f test.pdb -o test.gro -p toplo.top -ff prot so it'll read all of these files starting with 'ff' Then how can I deal with spc.itp and ions.itp files ?? Should I include the scp.itp and ions.itp files inside the ffprot,itp ??
