As part of the LMGP Suite for Windows by Jean Laugier and Bernard Bochu, there is are updated versions of CELREF and POUDRIX. Celref has a fix that for refining on cubic materialsm it will no longer diverge when the given a value was too far from the true one. Poudrix can now output simulated patterns in CPI (and a CPD format that describes multiwavelength situations) ====== As a reminder: Celref is a complete GUI based unit cell refinement program that can import raw data files and peak profile files, calculate lines based on the spacegroup and auto-select/auto-match calculated to observed peaks. Poudrix is a powder diffraction calculation program that also is able to use either "Brenann and Cowan or Sasaki" Anomalous Dispersion data to calculate the contribution of f' and f'' - plus can plot in 2-theta and Q-space. Thus it is very apppropriate for simulating or looking at Synchrotron based experiments. Lachlan. -- Lachlan M. D.
