[PyMOL] turn light routine

[Laurence P. <Lau...@ic...>]

I'm having a problem with the routine described a few months ago for 
rotating the direction of the light source when the picture is rotated 
for making a stereo pair.

The problem is as follows :

PyMOL>run turn_y_light.py
Traceback (most recent call last):
   File "/Applications/PyMOL/Darwin/modules/pymol/parser.py", line 186, 
in pars
e
     execfile(args[nest][0],pymol_names,pymol_names)
   File "<string>", line 1
      def turn_y_light(rot):
   # assuming "rot" has angle in degrees
   rot_rad = math.pi*rot/180.0
   (X0,Y0,Z0)=cmd.get_setting_tuple("light")[1]
   X1= X0*math.cos(rot_rad) + Z0*math.sin(rot_rad)
   Y1= Y0
   Z1= Z0*math.cos(rot_rad) - X0*math.sin(rot_rad)
   cmd.set("light",[X1,Y1,Z1])
                            ^
  SyntaxError: invalid syntax

Any suggestions as to what I'm doing wrong ?
