<DIV><FONT size=2>Dear gms-users, I have a fundamental question to put
forward. If I want to construct a forcefield for an organic molecule of middle
size,which has about 100 atoms, how can I prove that my forcefield for this
molecule is correct? Althouth we can get ffgmx itp files from prodrg server, can
we be sure that these topologies are definitely correct? If we want to convince
others that our topologies are right, is there any criteria to compare
with? If I want to derive a forcefield for a
particular molecule, what should I do?</FONT></DIV>
<DIV><FONT size=2>Any suggestion will be appreciated, thanks very much in
advance.</FONT> </DIV></BODY></HTML>
