Re: [AMBER] "Free energy fluctiontions over trajectory in MMGBSA.py"

btw what I've found in the log produced by -deo is that all data has
been sorted in accordance to the frame number
i.e

Total Energy Decomposition:
Frame #,Residue,Internal,van der Waals,Electrostatic,Polar
Solvation,Non-Polar Solv.,TOTAL

What would be most trivial way to sort all of those data primarily
based on the residue number ? In fact each time I'd like only to look
on the dynamics (as the function of the frame number from 1st column)
of the total energy (last column) of the one chosen residue (taken
from the 2nd column).

Thanks for any ideas!

James
