Sir thanx for the reply, I have a hydrogen.pdb file which I have generated from chem sketch.HETATM 1 H1 HYD 1 -0.353 -0.022 -0.013 1.00 0.00 HHETATM 2 H2 HYD 1 0.353 0.022 0.013 1.00 0.00 HCONECT 1 2CONECT 2 1ENDI am using genboc -ci option to insert 100 hydrogen molecules in the solvated box containing water and protein.Now the topology file "hydrogen.itp" I am using definig hydrogen as a 3 point molecule.
[ moleculetype ]; molname nrexclHYD 2[ atoms ]; nr type resnr residue atom cgnr charge mass#ifdef _FF_OPLS 1 opls_966 1 HYD H1 1 0.475 2 opls_967 1 H
YD H2 1 0.475 3 opls_968 1 HYD DH 1 -0.950#endif[dummies2];Dummy from from funct a 3 1 2 1 0.5
I am confused if the pdb should also contain the dummy atom.Kindly give me a example as the theory in manual is little bit compactThanking youVipul
