jMol series nanoparticle cylinder

Here's a model of 212 nanoparticles on an invisible cylinder that has a radius of 100 Angstroms, and is about 400 Angstroms in length. Each nanoparticle has about 121 atoms, giving the model as a whole about 25652 atoms. We've been working on methods for analyzing lattice images of such decorated cylinders for evidence concerning the relationship between those nanoparticle lattices and the cylinder surface.

How would you approach this same problem with the model below? For instance, can you determine the lattice parameters and space group symmetry of the particles? Are the particles fixed in orientation with respect to the cylinder surface, or do they at least preferentially contact that surface with a particular set of lattice planes?

Note: After the opening rotation, the van der Waals atom radii are reduced to 0.5 Angstroms and perspective depth is turned off so as to simulate an HAADF image taken with an aberration corrected STEM. You can turn these back on, and invoke many other display options, with Jmol's javascript menus by right clicking on the model image.
