ribspline  method  [ spec atom-spec ] [ smoothing none | strand | coil | both ] [ stiffness  s ]

bspline: tan;
cardinal (unsmoothed): light blue;
gray balls: α-carbon positions

Ribspline sets the method of ribbon path calculation:

The options can be given in any order. Option keywords can be truncated to unique strings and their case does not matter.

The spec option allows limiting the command to certain models; molecule models containing any atom in atom-spec will be affected. Only one method can be used per molecule model.

The remaining options affect only the cardinal spline:

Other ways to control the ribbon path method are with the Selection Inspector and the molecule model attributes panel.
