Hi Wendy,
See if you can get an interactive shell on the cluster machine. Some systems
let you do this. With pdb you do "qsub -i".
If you want to check that your topology file is not corrupt you can run it
through Amber's rdparm. This will give you an error if there are problems
with the prmtop file. I doubt this is the problem though. Even if your Pt
parameters were complete trash you'd still get some form of output. Just the
results would be pretty meaningless.
Also try redirecting standard out and standard error to a log file you can
get at. E.g.
/usr/local/bin/mpirun -np 4 sander -O \
-i 1AIO-1D4-min.in -o 1AIO-1D4-min.out \
-c 1AIO-1D4.inpcrd -p 1AIO-1D4.prmtop \
-r 1AIO-1D4-min.rst < /dev/null >& 1AIO.log
Some queue systems let you do this, other don't...
> /usr/local/bin/wipe $hostlist
I'm not sure what this command does? Is it possibly deleting any log files
containing errors?
All the best
Ross
