Is it possible to load a trajectory where the number of particles in each
frame aren't conserved?
I initially tried to load a trajectory in xyz format but vmd only loaded the
first frame, I figured this was because the second had a different number of
particles.

Since this didn't work I tried something else as well. I kept the same
number of particles, but changed the names of the ones that should
be disappearing,
for example:
the first frame has 5 "Z" particles and 10 "M" particles. The second frame
has 7 'Z' particles and 13 "M" particles. And then I wanted to show only the
Z particles in each timestep.
 However, it seems that vmd uses the names of the particles in the first
frame and doesn't reupdate the name list as I step through time.

Is there a way to force vmd to re-update the names at each timestep. Or make
vmd load a trajectory with varying numbers of particles in each timestep.

Thanks,

Chris
