Hi Dr. Case,
Thanks for your help. I did convert the MOL2 file into PDB format, however,
the bonds I manually added between the C and N atoms in glutamic acid side
chain residues were missing in the PDB file. I'd like to note that I'm
using Acclerys' Discovery Suite software to create my MOL2 (and PDB) files.
Do you have any suggestions how to go about this problem? My initial guess
is that I can use tleap to manually add the bonds between the C and N atoms
in the PDB file. Your thoughts would be appreciated.
Regards,
Lili
