[Chimera-users] Guessing net charge

Hello, When computing partial charges in Chimera, the user is prompted to indicate the net charge of the "non-standard" residues. However, more often than not, the suggested value is correct. I would like to know how this guess is made and whether or not the net charge of small organic molecules can be guessed in batch mode using Chimera (or other tools).
