Use this little script to explore PyMOL's myriad settings.

Usefull for newbies and those with not so good memory skills...

To use:

  1. put the script in a file called
  2. from within PyMOL execute run
  3. try it out, see examples below.

Example 1: grepset light

cartoon_highlight_color        default
dot_lighting                   on
light                          [ -0.40000, -0.40000, -1.00000 ]
mesh_lighting                  off
two_sided_lighting             off
5 settings matched

Example 2: grepset trans

cartoon_transparency           0.00000
ray_transparency_contrast      1.00000
ray_transparency_shadows       1
ray_transparency_spec_cut      0.90000
ray_transparency_specular      0.40000
sphere_transparency            0.00000
stick_transparency             0.00000
transparency                   0.00000
transparency_mode              2
transparency_picking_mode      2
10 settings matched

Example 3: grepset ^trans

transparency                   0.00000
transparency_mode              2
transparency_picking_mode      2
3 settings matched

The Script itself:

from pymol import cmd
import pymol.setting

def grepset(regexp=''):
   "grepset" greps through the list of settings using a python
   regular expression as defined in the 're' module.
   It returns a list of settings/values matching the regexp.
   No regexp returns every setting.

   grepset [regexp]

   grepset line
   grepset ray

   Python re module

   from re import compile

   for a in pymol.setting.get_index_list():
         count = count + 1
         print '%-30s %s' % (setting, cmd.get_setting_text(a,'',-1))

   print '%d settings matched' % count
