The program tries it best to read/calculate the charge information directly
from the input. However, not all the input formats provide the charge
information: gout, mopout, etc. explicitly have the net charge information;
the partial charges in mol2 format can be used to calculate the net charge;
while pdb format does not have charge information at all. Therefore, net
charge must be read in just for some formats. By the way, the net charge
specified by the -nc flag always override the read/calculate one.
