[gmx-users] monitor the size of the computational box

2015-07-06 Thread Giannis Gl
Dear all,

I would like to ask what is the best way to monitor the size of the
computational box (i.e. the volume)
during a simulation. I know that it must stay constant during the
simulation but, in my case, it seems that it doesn't.
There is an error poping up when I try to use the gmx hbond tool,
specifically Your computational box has shrunk too much,
and I've read that it is reccomended to plot the box volume as a function
of time. How can I do this?
Thanking you in advance,

John G.

The box is only constant with NVE or NVT, but with NPT it will not be.

Extract it from the .edr file.
