There is are new addition to the LMGP suite by Jean Laugier and
Bernard Bochu called "Truecell".
Truecell searches for more symmetric, higher symmetry cells that could
be a "better" solution to powder indexing data. This can be useful where
powder indexing programs favour small, low symmetry cells; and a
higher volume, higher symmetry cell could be a better solution.
The Chekcell graphical powder indexing helper and spacegroup
assignment software now has a version of Truecell included with it -
accessible via the "Cell Parameters" window.
(Truecell (and Chekcell) can read *.SUM Summary results files generated
by the Crysfire Powder Indexing Suite by Robin Shirley)
tutorial runthroughs showing Truecell in action are available
from the CCP14 website:
