[PyMOL] Active site pockets determination

[Oded K. <od...@in...>]

Hi,
I trying to assign and visualize the different pockets in protease 
active site (S3, S2, S1, S1',S2', S3') and then to compare these pockets 
in different proteases using the same calculation/approach.  What is the 
best tool/way for doing this with pymol?
Thanks,
Oded
