Peak Finding/Peak Profiling


  • CMPR for Windows and UNIX - can create Crysfire files and links to Dicvol and Treor
  • CRYSFIRE for DOS (works under Windows) - Integrating various indexing programs: ito, Dicvol, Treor, Taup, Lzon, Losh, Fjzn and Kohl; has rescaling and summary filing of solutions.
  • Chekcell Windows) - Graphical Powder indexing helper tool that interlinks into Crysfire. Knows about Spacegroups, has GUI Cell Transformation, Includes Le Page, Truecell and "Best Cell" cell selection based on parsimony of reflections.
  • EFlech/INDEX - Automatic Fundamental Parameters peak Finding/Profiling/Indexing from Joerg Bergmann
  • Powder/TAUP - Optimised for high Symmetry Cells
  • Powder v2.00 for Windows - Data manipulation, peak find, data evaluation. Interface for : - Dicvol (D. Lour) - Ito (Jan Visser) - Treor (Per-Eric Werner)
  • PowderX for Windows - Data manipulation, peak find, data evaluation. Has: - an integrated Treor90 (Per-Eric Werner) for Windows - an integrated DHKL for Windows
  • Treor, Dicvol, Ito - via Armel LeBail's site, Win95 Versions under What's New - with source code.
  • WinPlotR/WinDicvol/Fullprof which also comes with the latest Fullprof comes with WinDICVOL, WinTREOR and SUPERCELL.
