Dear Ross Walker,

I try to get the output file by using one of my friends' single PC. The
output file is listed below. It seems that the way I form my ".inpcrd"and
".prmtop" file by modifing the Amber parameters cause the minimization
problem. Would you give me some suggestions?

ps: There are a platinum atom in my molecule. And that is why I have modify
the Amber parameters.

Thank you!

 If you are using a pre-1994 force field, you
