I was wondering if one has access to the coordinates of the old
smoothed ribbon path through the protein or some good ideas on how to
calculate such a path. I wanted to have the ribbon_rider script I
wrote earlier follow such a path to avoid the jarring switching of
directions it currently does at each alpha carbon waypoint. I hoped
that breaking up the path into small enough bits (i.e. doing the
mvSinviewtravel thing one frame at a time and recalculating the
direction at each step) would achieve this. Perhaps it's mostly a
question for Warren, then, if he can tell me how the old ribbon path
A second refinement of this approach would be to have the path travel
down the center of alpha helices rather than curling around to each
Calpha but I wasn't sure if a running average approach would
guarantee this behavior as I could imagine the trajectory hugging
along one edge of a helix.
upgraded script version available shortly as I now have it working
from the command line rather than just from scripts.
Thanks for any ideas,
