Dear all,
I am trying to generate parameters for a protein containing modified
cysteine residue which I named as "CYL". First I run pdb4amber and
then took the output from the non-standard part. It has one nitro
group where N is positively charged and one oxygen is negatively
charged. If I run antechamber using amber then atomtype is set as "DU"
for that oxygen. But using gaff it set all atom types. Then
successfully I have prepared the prepin and frcmod file. But when I
run tleap, it is giving error of missing parameters parameters and
finally parameter file is not saved.
Can you please help me to get rid o this problem?
I am providing the required input files.
Thanks in advance..
