Brian,
 Thanks, it would be very convenient to be able to use a text file with 3
cols xyz, my usual way of writing trajectories. However all I find in the
Molecule menu using crd is parm and crd. How do you load pdb and crd? If I
figure out how to write a parm file can I just load it plus my trajectories
renamed .crd?
 BTW I said yesterday VMD choked on loading a big file of repeated pdb
files for different time steps. When I made the file smaller by taking just
a few time steps it read it but said it was one frame with more atom, the
number of atome = the true number times the number of time steps.
