Dear Amber users;
I have a ring system like shown in two attached files which is to be
used as ligands.When I run dynamics the ring system get distorted more
or less like cyclohexane ring. This should NOT happen according to atom
types.
I tried by changing atom type cc (cc.png attached) to cp (cp.png
attached) so that they correspond to carbon atoms attaching two rings.
But when I run dynamics (imin=0) Amber is considering rings to be
cyclohexane like not aromatic though I have not changed the atom types
of other atoms.
Should I define bond-order by myself and also should I change atom type from cc to cp?
thanks and regards;
JIomm
