Dear VMD wizards,

As I enjoyed the new and cool feature of RMSD Trajectory Tool from
VMD1.84 version, I found that if I clicked on "average" to compute RMSD
then an error message showed up as "Error: measure avpos: invalid syntax, no such
keywork: 0". However, when I clicked on "Top" then it worked just fine.
In my upper left selection box, I enterred "all" with no Backbone, no
Trace and no Noh selected.
Please help. Thank you very much.
