Dear All, I am trying to simulate the interaction between DNA, and CNT. But when I try to create the toplogy file with command
g_x2top -f ssdna.gro -o ssdna.top -ff select, I get the following error: Fatal error: Could only find a forcefield type for 119 out of 287 atoms I am using the oplsaa forcefield, and I suspect it is because atomname2type.n2t file doesn't contain all the possible bonds in it. Copy of my .n2t file is attached with the message. Could you please guide me how to add all these possible bonds in my .n2t file? I also downloaded the ffoplsaanr, ffoplsaano, from user contributed gromacs forcefields, but these packages also don't have .n2t file. Thanks, Majid
atomname2type.n2t
