There is a new 17th January 2001 version of Chekcell for Windows
graphical indexing helper tool for assigning cells and spacegroups
from powder data by Jean Laugier and Bernard Bochu - part of
the LMGP software suite.
(Chekcell interlinks with Robin Shirley's Crysfire powder indexing



A modified feature in Chekcell is that the "Density Explorer / Z Explorer"
is now a "Density Explorer / Z Explorer / MOLECULAR VOLUME Explorer"

Just put in your molecular formula - a "density range" or "Z range"
and click "Calc" to generate a Density/ Z / and Extimated Molecular
Volume and Ratios table applied to all your trial cells 
(irrespective you have only 1 or 5000 trial cells)

Updated runthrough of the "Density / Z Explorer / Molecular 
Volume Explorer" within Chekcell at:

The Density explorer menu can also be called within the Truecell and
LePage interfaces after generating derivative cells (super cells - sub


"Best Solution" results for automatically trying to work out the 
best Cell / Spacegroup combination can now be sorted.
