excellent. now you neutralize it by adding 12 Cl- ions, and then check the periodic table for an ion that has a charge of -0.69. if you can't find one, I suggest you have a look at the topology of your protein. presumably you have a wrong terminus definition that leaves you with a non-integer residual charge. cheers, marc _______________________________________________ gmx-users mailing list gmx-users@gromacs.org http://lists.gromacs.org/mailman/listinfo/gmx-users Please search the archive at http://www.gromacs.org/search before posting!
