Hello,
The other error message you're getting (when you use just sander) is
> *Unit 5 Error on OPEN: md-ala-neb_300K_equil.in *
Unit 5 is the mdin file. This means that sander cannot find
md-ala-neb_300K_equil.in to open it. Make sure you put this in the proper
directory. A common problem for PBS scripts is that you do not move to your
working directory. Add the line
cd $PBS_O_WORKDIR
before you actually run sander. PBS_O_WORKDIR is an environment variable
that stores the directory from which you submitted your script. You need to
change to this directory before you try to run sander so it looks in the
proper directory.
Hope this helps,
Jason
