Re: [AMBER] Query regarding unusual atom

there are really 2 questions here:
1) how do you generate library files for non-standard groups
2) how can you include selenium

for (1), look at the Amber tutorials at www.ambermd.org
for (2), you might be able to adapt the parameters for selenium included in
parm/frcmod.ff14SBmodAA
