# E A Merritt March 1993
# Illustration of composed figure using Raster3D
# (assumes libimage support from 4DGifts distribution kit on SGI)
#
# figure consists of E. coli enterotoxin (protein as spheres)
# binding to GM1 pentasaccharide (sugars represented as rods)
# protruding from cell membrane (plane)
# 
# Attach atom colouring to front of PDB file
#
cat chaincolours.pdb LT.pdb > temp.tmp
#
# space-filling representation of protein atoms
#
balls -h < temp.tmp > balls.r3d
#
# draw oligosaccharide as stick model
#
cat sugarcolours.pdb sugars.pdb > temp.tmp
rods  -h < temp.tmp > sugars.r3d
#
# combine protein description with sugar description and 
# add in description of plane surface lying below both.
# At the front goes a file containing the header records
# describing the view angle, image size, lighting, etc.
#
cat header2.r3d plane.r3d sugars.r3d balls.r3d > temp.tmp
#
# Feed the composite description through the rendering program
# and display using the ipaste utility
#

# Clean up before leaving
