Dear gmxers,
I try to simulate a complex system using gmx-4.5.1. I have carried out
the minimization without any errors, but when it comes to molecular
dynamics, some errors are printed and given below. How to deal with this
problem? Please give me some hints. Thanks a lot for any reply.
Yours sincerely,
Chaofu Wu, Dr.
