[gmx-users] charge distribution

[elham tazikeh]

Dear gromacs users
i d like to know about charge distribution in .itp file that how can fix
the charge of atoms
for instance, i simulated Aspirin in Human serum albumin, and i want to
know about their charges
in an article charge distribution was as below, but in my .itp file
(aquired by PRODRG server) i had 11 atoms instead of 13 atoms
please help me how can fix partial charges?
