Dear Amber Users,
I have a problem with created non-standard amino acids, Sulfotyrosine. I
created the force field for this sulfotyrosine (tys.frcmod and tys.lib)
using the "RESP ESP charge Derive Server", then using antechamber. However
when I load a sulfotyrosine pdb in tleap I got the following error, please
see below. Can someone tell me how to fix it or I can ignore it?
+Currently only Sp3-Sp3/Sp3-Sp2/Sp2-Sp2 are supported
+---Tried to superimpose torsions for: *-S-O3-*
+--- With Sp0 - Sp0
+--- Sp0 probably means a new atom type is involved
+--- which needs to be added via addAtomTypes
