Dear AMBER users,
In order to simulate a modified residue I have used a perpin and frcmod
file corresponding to the modification.
In that prepin and frcmod file I used an new atomtype for an atom Sulphur.
Like a standard prepin and frcmod file, information regarding this atomtype
are given in those files except the hybridization state,
I forgot to add this atomtype in tleap file by using command "AddAtomtype".
As a result leap gives a warning "Unknown atomtype".
I am not sure whether this cause any major problem or not, because I think
necessary parameters for this atomtype, except hybridization state, are
given in the respective prepin and frcmod files.
Please help me in this issue.
Regards
