Hello Francois
I have generated .off file for ATP using P2M, P1, P1, BN but when I am genating
frcmod file some of the parameter are missing.Since P2M, P1, P1, BN combination
was not there in script1.ff I have added this combination in this file and
geneated ATP3.mol2.earlier I generated .off file according to combination given
in script1.ff i.e. P2M, P1, P1, B5 but when I matched atom of ATP generated by
this combination with atom of ATP present in pdb of my protein having ATP, were
not matching there is no O5' which I have generated so I have added combination
P2M, P1, P1, BN.
So what I should do next to generate all the missing parameter in .frcmod file.
Here I am attaching .pdb file of ATP present in preotein .pdb file, .mol2,
.frcmod and .off file, I have genareted.
So please suggest me how to solve this problem.
