[Avogadro-Discuss] Unit cell builder

2013-02-27 Thread Richard Overstreet
Hello all,

I have a problem with the unit cell builder. I am able to successfully 
build a unit cell where a = b = c = 2 and alpha = beta = gamma = 108 
with NH3BH3. However, when I go to export the unit cell to NWChem 
format, or save as .xyz or .pdb none of the atoms created with the unit 
cell builder appear in the input file only the original or starting 
molecule coordinates appear. Additionally, the new atom coordinates do 
not show up in the Cartesian coordinate editor and labels do not appear 
on the constructed crystal lattice molecules in Avogadro. I am using 
Avogadro application version 1.0.3, library version 1.0.3, and openbabel 
version 2.3.0 on ubuntu 12.04 LTS x64.

-Richard

Can you try to reproduce this with Avogadro 1.1.0? There are a lot of new
crystallography features and unit cell creation has been rewritten.

Also, do you have the cell repeat options set? The cell repeat feature only
draws extra unit cells, but does not modify the actual crystal data. Use
the supercell builder if you want to add repeat cells to the crystal data.
