[Biopython] pdb file question

[Jessica Grant]

Hello,

I am trying to write a script that reproduces the crystal structure of  
a protein based on the information in the pdb file.  I have gotten  
kind of stuck using the SMTRY lines in remark 290.  It doesn't seem to  
contain all the information I need, at least the results I am getting  
don't look the same as when I produce symmetry mates in pymol, for  
example.  Has anyone any experience with this?  Thanks,

Jessica
