while using grompp I got a message :

" System has non-zero total charge: -9.999998e-01"

This is non integral charges. What should I add using genion?
+1 charge? Why am I getting such non integral charges?
I also checked for any breakage in the chain and found no such

Kindly suggest

The magnitude of the deviation from -1 (only 0.000002) is almost certainly due to rounding errors and is nothing serious in this case.
