Hi. I see that you can draw a line in VMD between two sets of coordinates
with tcl scripting:

draw line {0 0 0} {0 2 0} style dashed

Because this command draws a line between two static points, the line
will obviously be static.

I am wondering if a line can be drawn between two atoms instead two
points, so that the line can be updated to move with the atoms in a MD
I suppose this would work like the hydrogen bond representation.
Thanks for your help,
