[gmx-users] the total charge of a neutral molecules is not zero

[lammps lammps]

Dear everyone,

I use OPLS AA field to deal with a neutral molecules. However, the Total
charge is 8.500 e, not zero.

Are there other reasons for this problem except giving a wrong parameter due
to my carelessness.

I can not find the errors. Any suggest is appreciated. Thanks in advance.
