[chimerax-users] Worms?

[Boris Steipe]

Thanks Elaine!

The collada solution looks interesting.

Regarding the user interface, I had hoped that e.g. an attribute file could define tube radius at CA positions, with smooth interpolation between.

A python approach would be good as well.

Cheers,
Boris

It might be possible to use the ribbon path in ChimeraX, but the sticking point may be the lack of user-interface controls to vary ribbon width/height along the path, or even whether that would be possible given the way that ribbons are encoded.  Might be possible with python or by altering ChimeraX code, but somebody else would have to advise on that.
