[gmx-developers] suggestion: velocities.xtc

Dear developers,

there are several applications around for which the velocities in the 
simulation are interesting.

Therefore it might be interesting if mdrun would allow optional output 
of the velocities in xtc format. Using the trr file for velocity 
analysis is usually not convenient since it simply gets too large when 
writing to it in frequent steps. Probably it would be relatively little 
effort so implement this with all the xtc routines at hand. Of course, 
one mdp option like nstvxtcout would have to be added, too.

Have you ever intended to implment something like this?

Cheers, jochen
