Hello,
I don't know if every body is aware of this: there is a web page
(
http://ambermd.org/doc/AtomTypesTableWorkspace.xhtml) that lists all
the atom types that are defined in the different "amber" force fields.
Thanks to "git blame", the author is Daniel from a
AtomTypesTableWorkspace.lyx file (available in the doc/ directory of the
amber master tree) by Lachele. Thanks to both of them for providing this
useful information :-).
From that file, it seems that CG is already defined in GLYCAM...
Gerald.
P.S.: It dates from 2012 and does not include ff14SB, but there should
be some way to automate the process.
