Hi,
I've attached a script that can do things like this; it contains an
accessory proc for drawing arrows, and then the proc procplot, which
draws arrows between the first and last frames of all atoms in your
structure.

Just call it by typing, in the tkcon,
source porcplot.tcl
porcplot mol gmol

mol is the molid of the molecule you want to operate on, and gmol is the
molid that will receive the graphics.
Best,
Peter
