Abstract

Comparing crystal lattices is necessary for several uses: databases of unit cell parameters, Bravais lattice type determination, clustering of cells from serial crystallography at XFELs and synchrotrons elimination of duplicate and near duplicates in crystal structure prediction. The talk will include a brief, simple review of linear algebra. The mechanics of measuring the difference of pairs of unit cells will be discussed ("distance" between lattices). That leads naturally to a discussion of how to determine Bravais lattice types.
