Hi all.
I am working with CHARMM FF and trying to run a small ligand inside a
protein.
I have a problem with the new parameters.
The problem is maintaing a cp3 configuration of a carbon on a ring. The
species is like
R--------------------R
\ H /
\ | /
N ----C*-----C
|
O
|
H
And I am using improper parameters C* H O C and C* H O N ,but it doesnt
solve the C* cp3 problem.
Can any of you have any experience with such a problem?
Many thanks.
