First of all, thanks for the tips from everybody. I tried David Smith's method
but I got stuck in step 3 (described below).
In order to run the perl files i must use "./perl_name". However, in step3 i
must use two files at the same command line and i get the following message :
sh: ./enerAmber.pl: No such file or directory
I also could not set the home directory for MMTSB(probably i do not have the
permission). Is there any other way to use ensrun and enerAmber separately.
Hope my question is clear...
Thanks in advance.
