Hi Ramin,
In whatever scripting language you prefer, for each residue/residue pair:
1. Create a TCL script to run NAMDenergy for that residue pair.
2. Create a submission script for your queuing system that calls the TCL script.
3. Add your submission command (i.e. qsub NAME1) to a batch file so you don't have to submit each one individually.
It is typical to have a cap on the number of jobs that can be in the queue for a single user, so I suggest using multiple batch files to submit the jobs.
Good luck,
Brittany

Dear Brittany,
Would you please let me know more about your script.
I would like to do the same.
Thanks
Ramin.

I perform residue/residue energy calculations by creating batch scripts to perform each pair as an individual calculation so I can run them in parallel. It isn't fast, but it is doable.

Hi,
I don't think there's any way to make the existing NAMDEnergy plugin
run much faster, as it basically just writes a configuration file
and starts NAMD to do the calculations. The only suggestion I have
is that since it runs NAMD, you might be able to do your specific
calculations in some more efficient way than the NAMDEnergy plugin
knows how to do, but you would have to become an expert at doing
these energy evaluations using the NAMD input scripts, etc. There may
also be other tools that can do these calculations more rapidly than
NAMD does, since this is a somewhat unusual use case for NAMD, and
there may be specific tools that are designed to be much faster
for this precise type of calculation. Sometime in the next year we
hope to have an alternative to NAMDEnergy that is much faster for
some of the cases that NAMDEnergy doesn't handle well, but I can't
say for sure if that will address your particular issue or not.
Cheers,
John Stone
