[gmx-users] Energy minimization

[Oliver Konrad]

Dear gmx-users,
I´m an absolute beginner in the field of MD and especially gromacs.

I´ve tried an energy minimization of the spc216.top file from the gromacs 3.0.5 
package with the steep integrator. In step 36 I got always the error message
"Water molecule starting at atom 451 can not be settled!"
Do I have to modify the spc216.top file ??

Thanks in advance
