Antechamber recognize element/atom type based on the atom names.
Therefore, you may manually modify the atom names, for example, change
AP to PA, A01 to O1A.

Hello, Amber:

I try to load a ligand (named as FAD-1 here), and use abtechamber to
creat prep file. Here is how I did:

guanine.1% setenv AMBERHOME /usr/local/amber7
guanine.2% antechamber -i FAD.pdb -fi pdb -o FAD.prep -fo prepi

 Unrecognized atomic name AP , exit
 Unrecognized atomic name AO1 , exit
 Unrecognized atomic name AO2 , exit

I search the mail list, but hard to find the answer. I have included the
pdb file as an attachment. I use Amber7.

Thanks for any suggestion.
