A very quick question.

Can someone confirm that atomic coordinates are stored as in the  
traj.xtc file in units of nm (as opposed to Angstroms)?

I am trying to figure out whether or not in the g_msd program reads in  
nm or Angstroms. The standard output of the xy graph is nm2 and ps. I  
can't see that the units are being divided by 10 in the g_msd code so  
I am guessing the traj.xtc feeds in the units in nm.  Just want to be
