[PyMOL] Content of unit-cell

[Marc S. <mar...@mp...>]

Hi Pymol-users,

apparently no one has asked this question before or I wasn't able to 
find it in the archive:

I would like to display all molecules of a crystal structure which lie 
within one unit-cell.

I do know how to display the cell and how to display symmetry-mates, but 
how do I tell Pymol to cut away everything outside a certain volume 
("symexp [bla, bla,] radius" does not do it apparently), i.e. the 
unit-cell itself?

So what I want is simply spoken to display a brick of xtal the size and 
shape of the unitcell with all atoms inside, but none outside.

Is that possible?

I have tried to remove parts manually after adding symmetrie-mates, but 
this is painfull for very large structures (I have one with a 700 
A-axis...).

Thanks in advance!
