There are new versions of the following software as part
of the LMGP Suite by Jean Laugier and Bernard Bochu. 

OrientExpress (Laue Crystal Alignment software), 
Dispano (Anomalous dispersion software), 
Poudrix (Powder diffraction Pattern Calculation software), and
Celref (unit cell refinement software) 


Tutorial run-throughs:


A slightly modified/edited note from the authors:

1-DISPANO. (Anomalous dispersion software)
This new version makes it  possible to display 2 elements on the
same graph. Warning: The Brennan and Cowan data were given by DABAX with an
insufficient number of digits for the energy values. Manuel Sanchez Del Rio
(ESRF) sent me a new corrected file.  It will be the same for Poudrix.

2-Poudrix updated for the reason above.
  (Powder diffraction Pattern Calculation software)

3-Celref (unit cell refinement software)
  No longer unzooms on calculating HKLs allowing it to be friendlier
  for helping with spacegroup assignment of powder patterns.

4-OrientExpress (Laue Crystal Alignment software) with minor corrections:
-The display of the reorientation angles is different.It is now possible to
     make a simulation of each of the possible settings.
-Window simulation: it is now possible to type the rotation angles (x,y,z)
     to simulate the rotation.
-The Help file was slighly modified.
-Will now handle JPG files.
