Compute a protein backbone. The tube selects the atoms marked CA but pass only through the ones placed between a N and a C atoms.
|structure_in||MoleculeType||Molecular structure data.|
|Points added||slider||Points added between two CA intersection nodes.|
|Smoothness||slider||"Tension" parameter of the interpolating spline: a value of 0 creates stright tube segment between nodes; 1 is the normal value and higher than 1 accentuate curvature.|
|Tube scale||slider||Radius of the tube.|
|Tube facets||slider||Number of sides composing the tube wall.|
|Mesh only||toggle||If set the backbone tube is colored by the color set below. Otherwise the color is set from the corresponding atom scalar value.|
|Mesh color||color editor||Sets the backbone tube color.|
|obj||DefaultObject||The renderable version of the backbone tube.|
The coloring of the tube depends on the current active AVS/Express colormap, not the one selected for the molecule rendering in Draw Structure.
