RE: [AMBER] Running PTRAJ command line scripts in background

Hi Robert,

This is real easy to do. The key is that ptraj can read commands streamed
from standard input. So just put the commands you want into a text file (say
my_job.in). E.g.

trajin foo.mdcrd.1
trajin foo.mdcrd.2
trajout bar.mdcrd
...

Then run ptraj with:

$AMBERHOME/exe/ptraj < my_job.in >& my_job.out &

This will background the job and write all the output to the file
my_job.out.

If you want it to run even after you close the terminal then you just have
to prefix it with nohup. E.g.

nohup $AMBERHOME/exe/ptraj < my_job.in >& my_job.out &

All the best
Ross
