Ribbons File Types

Ribbons requires generation of special files for display. All files are ASCII. All files may be generated from *.pdb files and the auxiliary programs provided.

All file names should follow the convention `MoleculeName.RequiredExtension'.

File named `Name.model'
Required files with required filename extension:

• *.model ---- required to define a 'model' and display anything

eg: protease.model

One or more files named `Name.*'
Optional files named '*.required_filename_extension':

• *.atoms ---- required to display spheres of corresponding model
• *.bonds ---- required to display cylinders of corresponding model
• *.coords ---- required to display ribbons of corresponding model
• *.ribbons ---- required to display ribbons of corresponding model
• *.texts ---- required to display strings of corresponding model
• *.polys ---- required to display polygons of corresponding model
• *.ndots ---- required to display dot surface of corresponding model

eg: protease.texts

Graphics Primitives
Optional files with recommended (but optional) filename extension:

• *.pdb ---- atomic coordinates used to create all files
• *.ss ---- sequence and secondary structure for *.ribbons
• *.sph ---- sphere primitives associated with *.atoms
• *.cyl ---- cylinder primitives associated with *.bonds
• *.dot ---- dot/normal primitives associated with *.ndots
• *.tri ---- triangle/normal primitives associated with *.polys
• *.color ---- color mappings of residue or atom or scalar types
• *.rgb ---- SGI format image file

eg: protease_site.sph

Optional files with highly recommended (but optional) extensions:

• *.orient ---- viewing orientation of a model
• *.matter ---- material and lighting properties, for `color'
• *.defaults ---- style settings

eg: protease.orient
