Hi Marcos,

I tried as you said, unfortunately it doesn't work. I got these two error
messages when submitting the script:

"
Name "main::wd" used only once: possible typo at
./prepare_runs_0-90-modified.perl line 3.
Preparing input files
Processing dihedral: 0
Can't exec "qsub": No such file or directory at
./prepare_runs_0-90-modified.perl line 27.
Processing dihedral: 3
"

The "Can't exec .." is repeated for all runs till dihe=90. ( here is the
files modified)

Do you think I should change the qsub command when preparing the input
files, if so how ?

Note I simply renamed ala_tri.rst file with 03_prod_60. Your help is
really appreacited.

Emanuele
