dear all,
if i read a nmr-style pdb into vmd (many models with same atom number) and do a
atom selection like sqr(x)+sqr(y)+sqr(z) > 0 (only atoms not in origin) the
selection is only made correctly for the first model and not updated neither
when running through the trajectory nor visualizing all frames at once.

i understand that updating each step would slowdown the process but in this case
necessarily. is there a workaround like for secondary structure assignment
