Is there any methodology to increase the no of cores (for faster computations) being used in the command line for mmpbsa claculations:
g_mmpbsa -f md_0_1.xtc -s md_0_1.tpr -n index.ndx -i pbsa.mdp -pdie 2 -pbsa -decomp
python MmPbSaStat.py -m energy_MM.xvg -p polar.xvg -a apolar.xvg
python MmPbSaDecomp.py -bs -nbs 2000 -m contrib_MM.dat -p contrib_pol.dat -a contrib_apol.dat
The system is taking too long (much more than expected time) to complete a calculation?
Ayesha Kanwal I think your pc's python package need upgradation.
Hi Safa Aouinti Anwesh Pandey while calculating python MmPbSaStat.py -m energy_MM.xvg -p polar.xvg -a apolar.xvg
every time i get an error how to resolve it and why it happens ?
Traceback (most recent call last):

hi Anwesh Pandey when i calculate average binding energy in result of this electrostatic and binding energy came positive . what would be the reason of that ?
I have used pdie 2 and i also had used pdie 8 but still these energies are positive. how to deal with it ?

See, these disscussions could be of some help:
