ADL: hemin iron charge

Thanks for reply! 

I just opened the PDBQT file (after preparation and saving)with Notepad, edited the Fe charge to +3. No problem when I run vina with the edited file, however, when I reopened the edited file using ADT, compute Gastegeir charge, ADT did not recognize the edited charge. Why?

the results I got with the edited file is almost the same with the non edited file, so I am wondering weather vina recognize the edited charge as well?! 

could you please comment on that??

My guess is that your edit violated the syntactic conventions of the
file format. Try feeding the edited file to Vina. If it's bad, Vina
should reject it.
