[Chimera-users] Coloring model represented as PipesAndPlanks

As far as I know the Pipes and Planks have only been whatever colors
are shown in the PipesAndPlanks dialog, and these colors can be
different than the protein structure. It doesn't matter whether the
model number is the same or different as the protein structure for
purposes of coloring.
Is it possible you were using Axes before? With Axes/Planes (now Axes/
Planes/Centroids in version 1.5), each helix can be shown as a
cylinder, and each cylinder can be colored however you like. This
tool does not make "planks" for beta-strands, however.
With molmap you can specify the new map's model number, for example:
molmap ligand 5.0 model 4
The model number doesn't affect coloring. The reason one might want
models to have the same number is that it prevents you from moving
them separately (prevents decoupling their positions/orientations).
I hope this helps,
