Hi All

I am trying to read a gromacs .xtc file containing 11 frames into vmd using
the following:

mol load gro temp.gro
mol addfile {temp.xtc} type {xtc} first 0 last -1 step 1 waitfor 1 0
animate style loop

set nframes [molinfo 0 get numframes]
puts "the number of frames is $nframes"

However, nframes is only 5? On the GUI, VMD can see 11 frames, but why is
nframes output as 5 ?
