[Chimera-users] UnitCell.molecule_center(): Attribute does not exist

[Alejandro Virrueta]

Hello all,

I'm trying to execute the script to fill out the crystal unit cell found
here:
http://www.cgl.ucsf.edu/chimera/docs/ProgrammersGuide/faq.html#q13

However, I get the error that UnitCell does not have the 'molecule_center'
attribute (code line ~12). I checked with dir(), and yeah, it's not there:

['ModelessDialog', 'Unit_Cell_Dialog', '__builtins__', '__doc__',
'__file__', '__name__', '__package__', '__path__', 'chimera', 'dialogs',
'find_model_by_name', 'outline_box', 'place_molecule_copies',
'remove_extra_copies', 'show_unit_cell_dialog']

Where did the attribute go?
Is there some other module I could use?
Could someone explain (or direct me to some webpage that explains) the
process of expanding the ASU and I can write my own script.

Any help is greatly appreciated! Thanks!
Alex
