POWGEN for comparing structure factors with input powder patterns

The graphical interface to the new (exceedingly alpha) Xtal program POWGEN is shown. Powder patterns in a range of formats are read by the equally new program ADDPAT. ADDPAT creates a .pat file suitable for POWGEN, where it can be visually compared with a calculated pattern based on your current structure.

POWGEN is not a powder indexing, phase identification or Rietveld refinement program. It simply provides a means for clarifying whether your current known structure matches your measured powder pattern, subject to a limited number of adjustable parameters.
