Hi Martin,

The following works for me, although I needed to change 'protein' to 'polymer'. Is 'protein' normally supported as a selection? It doesn't seem to be in 1.4.1.

from pymol import cmd
cmd.fetch('1rx1')
a = cmd.get_extent('polymer')
print "a is",a

Hope that helps,

-Michael

Dear all

I found that PyMOL offer the cmd.get_extent('protein') function, which
returns the dimensions of the selection.
Is it complicated to make this function available from within an
ordinary Pythonscript?

Thanks for hints.
Martin
