Hi Dr. Case,
Thanks for your reply. I tried running antechamber initially (as you
prescribed), but my converted mol2 file is really weird. The carbon atoms
get converted to Californium and Cerium atoms. There's even a Neon atom in
the structure, as well as many "Unknowns". I have no idea how the carbon
atoms got converted into them.
I have attached the original PDB and mol2 files for your convenience.
Thanks,
Lili
