Hello,

  I am trying to use this script:

http://www.ks.uiuc.edu/Research/vmd/script_library/scripts/trajectory_path/
<https://ewa.epfl.ch/owa/redir.aspx?SURL=-XIwpi3phwsVq54Qgbd-NJ_5lkgmK5aQGTkckEriak_bdi6o9N3SCGgAdAB0AHAAOgAvAC8AdwB3AHcALgBrAHMALgB1AGkAdQBjAC4AZQBkAHUALwBSAGUAcwBlAGEAcgBjAGgALwB2AG0AZAAvAHMAYwByAGkAcAB0AF8AbABpAGIAcgBhAHIAeQAvAHMAYwByAGkAcAB0AHMALwB0AHIAYQBqAGUAYwB0AG8AcgB5AF8AcABhAHQAaAAvAA..&URL=http%3a%2f%2fwww.ks.uiuc.edu%2fResearch%2fvmd%2fscript_library%2fscripts%2ftrajectory_path%2f>

for visualizing the trajectory of a single atom with VMD,
here with index 59. I am a beginner with VMD, and I just wrote in
the TkC console:

> source traj.tcl
> set crystal [atomselect top "index 59"]
atomselect11
> traj $crystal scale

but I finally end up with the error.

Illegal molecule specification 'index 59': Could not
find molecule 'index 59'. mol new operates on one molecule only

How can I solve this problem?

      Thanks a lot for any help,
