Additions, Corrections Welcome
NOTE: It is a good idea to independently cross validate spacegroup and structure transformation and look for any inconsistancies.
NOTE 2: Some of these programs may require dummy atoms to be inserted if you are just transforming a cell or HKL data. It is possible of course to recalculate HKLs with the new cell with a variety of software.

Given the P and Q augmented matrices, is there a simple matrix equation for converting the lattice parameters (including angles)? I know that I could convert them via a cartesian referece, but I thought that there might be something more elegant. -Andrew |
