[gmx-users] Problem with Charges

[faride badalkhani]

Dear all,
I have parameterized a relatively large molecule (136 atom) with PRODRG
server, and then I assigned charges and charge groups in a building bock
style manner. I know that my system include a total +8 charge, but when I
execute genbox command i receive the following note:

System total charge: 0.000

what should I do to overcome this problem?

Truly yours,
Farideh
