[Chimera-users] Problem with charges when writing mol2 file with a python script.

I'm trying to write a simple python script to open a mol2 file with a ligand, add hydrogens, add charges and write it into another mol2. The script is this: ----------------------------------------- import chimera                                     #1 from chimera import runCommand                     #2 runCommand('open ligands/lig_in.mol2')             #3 runCommand('addh')                                 #4 runCommand('addcharge')                            #5 runCommand('write format mol2 #0 lig_out.mol2')    #6 ------------------------------------------ The result mol2 file does no contain any charges. However, if a run another script that is exactly like this but does not contain the last line (#6),  and then execute the command 'write format mol2 #0 lig_out.mol2' manually, the mol2 file contains charges. I don't understand why there is a difference with both methods. best regards. javier
