[L.M.D.Cranswick...@dl.ac.uk]

Notes on "Progress in Automatic Powder Indexing" 
(presented at EPDIC-7, Barcelona, Spain, 20-23 May 2000 
by Robin Shirley, School of Human Sciences, University of 
Surrey, UK) are now on the web at the CCP14 web site:

--------------------------------------------

These notes look at:

 What powder indexing is and why it?s necessary;
 Parameter space vs index space;
 Why indexing is difficult, including the character of its solution space;
 A survey of methods and programs, including more recent approaches;
 The Crysfire suite: indexing for non-specialists;
 Some current issues and opportunities;

 (And finally, a live Crysfire demonstration)

--------------------------------------------

There will also be a new version of Crysfire for DOS
update "very soon" (and will be announced on the lists 
and CCP14 site)

Crysfire information, tutorials and homesite at viewable via:
