Hi Justin,
thank you for your quick reply.

When you say:

"..Probably by analyzing them individually with mdrun -rerun to recalculate
each frame.  Tedious, but can be easily scripted..."

do you mean I have to run g_enemat module using -b and -e options in order
to set the first and the last frame to read from trajectory?
If not, could you please suggest me the correct way to do so?


Not what I was suggesting, but using -b and -e should also work.

thank you again.

Federico

Dear all,
I would like to extract the interaction energies (LJ
and electrostatic) between each residue pairs from my trajectory.
The g_enemat tool generates only 3 xpm image files (Coul-SRemat.xpm,
LJ-SRemat.xpm, totalemat.xpm) but not a "data" file with
the residue-residue interaction energies I'm looking for.
Is there a way to get these numbers? Or have I to read the xpm "matrix"
and
convert all those letters to the corresponding energy values?


Yes, you have to map it out based on the .xpm labels.


  Finally, is there a way to get pairwise residue-residue interaction energy
values from each snapshot of my trajectory ?


Probably by analyzing them individually with mdrun -rerun to recalculate
each frame.  Tedious, but can be easily scripted.
