Ribbon Dimensions Panel Widget.

Uses Motif Widgets ( Choice, Toggle, Scale, Push ) to adjust dimensions (sizes) of ribbon drawings.

Widget Name (Widget Type) --- description of function

• Ribbon Width (Scale)
  -- set width in angstroms across the ribbon for the current selection of Ribbon Lists.
• Sheet/Helix/Coil Widths (Scale)
  -- like Ribbon Width, but apply only to that secondary structure type.
• Ribbon Depth (Scale)
  -- set depth in angstroms perpendicular to width for the current selection of Ribbon Lists (controls linewidth if DrawStyle is Lines).
• Sheet/Helix/Coil Depths (Scale)
  -- like Ribbon Depth, but apply only to that secondary structure type.
• Arrow Head (Scale)
  -- behaves like Ribbon Width, to set width at `point' of the arrows.
• Arrow Base (Scale)
  -- behaves like Ribbon Width, to set width at the start of the arrows.
• 3-10 as Helix (Toggle)
  -- treat all 3-10 helices (SS code '3') as helix (default). Else as coil.
• Helix Shift (Scale)
  -- shift the spline curve out from the helix axis.
• MRC Analysis (Toggle)
  -- initiallize wavelet transforms. Note: prompts for std.input.
• Float MRC level (Toggle)
  -- interpolate fraction wavelet levels. Else allow only integers.
• MRC Level (Scale)
  -- set the wavelet level to approximate ribbon curves.
• Close Panel (Push)
  -- dismiss the panel
• Panel Help (Push)
  -- show this help screen

Hints:

For the MRC wavelet analysis, first set the ribbons style to Circle, and set dimensions of width==depth, then toggle on. It will prompt for input, and initiallization may take a while for large proteins. Play with the level & watch. Still experimental. MRC stands for Multi Resolution Curves (see Wavelets and Molecular Structure on my web site.)
