Hi, I am using v-4.5.5. I have a system of DNA nucleotide & *two* OH radicals solvated in water.
The topology file has the following records in the end: [ molecules ] ; Compound #mols DNA_chain_X 1 SOL 351 However, when I did gmxdump after running grompp, I see the following: moltype (0): name="DNA_chain_X" ............... ............... residue (2): residue[0]={name="DTMP", nr=1, ic=' '} residue[1]={name="OHN", nr=2, ic=' '} moltype (1): name="SOL" .......... .......... residue (1): residue[0]={name="SOL", *nr=1*, ic=' '} Aren't we recording the number of solvent residues? I was expecting nr=351 for SOL; the number of water molecule I have in the system. As I get nr=2 for OHN Thanks, Pradip Biswas -- P. K.
