Dear all
I use charmm27 as a default for making my force field file , and now I
need .n2t file while charmm27 don't have .n2t file .
I use oplsaa as a default for .n2t file and g_x2top and could not
read this file .
That simply won't work. The atom-naming schemes are totally different.
Without knowing your overall objective (including why you think charmm27
is a good template, and why you think you need to use g_x2top), it's
hard to say anything more.
