[Chimera-users] pipes and planks

[Kyle Morris]

Hi Elaine,

Thanks for this, very helpful! I hadn’t realised that pipes picks up the color from the original model and had been forcing it with helixColor. Can work around using this knowledge.

ChimeraX looks like it’s going to be awesome.

Thanks,
Kyle

Each whole pipe would be the same color, though, taken from the ribbon color of the first residue in that helix; it is not divided into independently colorable per-residue segments. The new pipes model should overwrite the existing pipes model, but f you seem to be getting duplicate models, extras can be closed using the Model Panel (under Favorites in the menu).
