The units in the prmtop may not be what you expect. It would be safer to
update your input file and regenerate prmtop/inpcrd from that, then use
the new prmtop with your latest coordinates. Diff the prmtops and you
should only see the charge difference.

Is anything else would also be updated? In other words, is there any other section related to the CHARGE and must updated along the new charge?
