Hi all,
I'm trying to generate a series of rendered images using the API. The script
itself works fine but the only thing that isn't being rendered is the unit
cell. I have been using the cmd.show(representation='cell') command to try and
get the unit cell to show but it doesn't appear to be working and there is no
documentation on how to show the unit cell using the API.
This is one of the structures I have been trying to render (called
"structure.pdb"):

This is my rendering script:
from pymol import cmd
#Viewing settings
cmd.load("structure.pdb")
cmd.set('orthoscopic', 1)
cmd.show(representation='cell')
#Ball-and-stick model
cmd.show('spheres')
cmd.set('sphere_scale', 0.33)
cmd.show('sticks')
cmd.set('stick_radius', 0.2)
#Colours
cmd.color('grey', 'name C*')
cmd.set('stick_transparency', 0.05)
cmd.bg_color('white')
cmd.set('ray_opaque_background', 0)
cmd.set('ray_shadow', 0)
#Render image
basename = 'Structure'
cmd.zoom(complete=1)
cmd.ray(1024, 1024)
cmd.png(basename+'_Z'+'.png', dpi=600)
cmd.rotate('y',-90)
cmd.rotate('z',-90)
cmd.ray(1024, 1024)
cmd.zoom(complete=1)
cmd.png(basename+'_X'+'.png', dpi=600)
cmd.rotate('z',-90)
cmd.rotate('x',-90)
cmd.rotate('z', 90)
cmd.ray(1024)
cmd.zoom(complete=1)
cmd.png(basename+'_Y'+'.png', dpi=600)
cmd.quit()
Many thanks,
Shay Chaudhuri
