[cctbxbb] Reindexing matrix -> transform orientation matrix

[Winter, G (Graeme)]

Hi Folks,
 
I'm just trying to figure out how to do the following, given a triclinic
orientation matrix (real or reciprocal space, differ by .inverse() ->
triclinic unit cell)
 
(like iotbx.lattice_symmetry) stuff -> set of unit cell, Bravais lattice
options with reindex operations
apply reindex operation to orientation matrix -> new basis a, b, c
 
The former I have historically done using iotbx.lattice_symmetry but
given the move from python to cctbx.python, it seems wasteful. I looked
at the source code but got a little confused. The latter seems to be
more problematic - even reconstructing the change of basis from a known
reindexing operation I don't seem to be able to get the right answer :o(
 
Has anyone done anything like this with the CCTBX tools?
 
The context is autoindexing with XDS using a full sweep's worth of
images, then inspecting the indexes in SPOT.XDS based on the contents of
XPARM.XDS.
 
Thanks,
 
Graeme
