[gmx-users] Distance Difference Map

[Paul Czodrowski]

Hi Gromacs,

I read something about evaluation of the motion of a protein: they use a
so-called "distance difference map", which take one protein strucuture and
calculates sequentially the distancse between the first C-alpha atom and
all other one. Then it continues with the second C_alpha etc.
I know that this should be really fast to program from scratch, but I'm
not a Pro. So I wanted to ask, if you can something like that with
Gromacs.
I know about the program g_msd, but this is limited to a atom (or a group
of atoms) and their initial position.

Cheers,
Paul
