[gmx-users] forcefield format

[Derrick Guang Yuh Lee]

dear gmx-users

i am attempting to make some edits to a forcefield and was curious of the
format of the rtp files. i.e. if using the ffoplsaa.rtp, under the residue
ALA, subsection atoms, there is the following:

[ atoms ]
    N    opls_238   -0.500    1

obviously the first is atom type and the second column is an identifier,
what are the remaining two? thank you in advance.


sincerely

 - derrick
