[phenixbb] polygon and membrane proteins

[Pavel Afonine]

Hi Pascal,

what are the selection criteria that can be used to identify those 
structures in PDB? Any specif keywords in PDB file header? Can it be 
done (such a selection) in a robust way (with minimum guesses and 
resulting errors)?

If you can formulate these selection criteria, then I will be able to 
add it to a future version.

Pavel.
