I am trying to implement the script "PorcupinePlot.tcl" (see attached)
for a series of alpha-carbon only snapshots of my protein (in PDB
format), which have been processed with PCA analysis (in GROMACS) such
that they provide a trajectory of relevant protein movements.

I am trying to implement the script with VMD 1.8.6 on my PC, to
generate a porcupine plot figure of the results, but I cannot figure
out how to execute it. Does anyone know how I would go about
implementing this script?
