Dear Gromacs Users, I am trying to build topology file containing two different molecules (A molecule, and B molecule)
"A" and "B" molecule contain three beads each. "A" molecules start from 1 to 600, and then "B" molecules start from 601 to 900 in conf.gro file. I created topol.top file (this is coarse grained topology) as follow but it does not properly worked. The gromacs seems to read only "A" molecule. Would you please let me know where the problem is? Thank you very much.
