[gmx-users] analyze an md run

[Joern Lenz]

dear users,

i have modelled a system containing a protein plus a DNA and water molecules.
Now I am wondering, if it is possible to use s.th. like g_energy to plot the 
fluctuation of energy, temperature, pressure etc. only of the protein and the 
DNA and NOT with the water molecules. that is because i want to compare 
several simulation runs and their changes in energy, temp ... .

Is there any option to do so ? I also have defined lots of index groups for 
distinguish between groups in the system.

So I would be very happy if you have a solution for my problem, thank you very 
much in advance and have a nice evening.
greetings
joern
