New Match! version 3.2.0

April 22, 2016

Today we have released a new version 3.2.0 of Match!, our software for phase identification from powder diffraction data. The new version provides a rather large variety of improvements and bug fixes:

  • The reference database is now switched automatically when a document is loaded that was saved using a different reference database than the one that is currently used.
  • New batch script command "new_document" (-> File/New)
  • New batch script command "use_ref_db" (select reference database from within script), e.g. use_ref_db("PDF-2 Release 2015")
  • A data sheet for the refined structure and parameters has become available, in addition to the one for the original reference database entry data.
  • New data sheet option "Display peak positions as 2theta or d-values" on new "Data sheet" options tab
  • New command "Pattern/Increase resolution" increases resolution by interpolating new data points between the original ones.
  • New option "mode" for peak range selection on "Peaks" tab of "Restraints" and "Additional entries" tabs enables the user to exclude all entries that have peaks within certain 2theta ranges.
  • New command "File/Export/Peak data (Rietveld)" exports the peak data resulting from Rietveld refinement from the currently marked Match list entry.
  • Auto save option on the "General" tabsheet of the "Options" dialog (default: active, save every 10 minutes).
  • The import of cif-files into the User Database Manager is much faster by now.
  • Peak searching sensitivity has been slightly improved (some users may want to adjust their default peak searching sensitivity)
  • A new page "Batch Scripting" has been added to the online help in which all commands available for scripting are listed and explained along with their parameters.
  • Several bugs have been fixed:
    • Due to a bug, Match! did not distinguish between U_iso and B_iso when importing isotropic atomic displacement parameters from ICDD PDF-4+ databases.
    • A severe bug in the figure-of-merit calculation devaluated an entry if at least one of its peaks contributed only to a minor part of an experimental peak intensity.
    • A bug causing displaying problems of filenames containing more than a single '.' character has been fixed.
    • Due to a bug, changing the restraints pre-selection did not always lead to the expected result (some input boxes kept their previous values).
    • Peaks from reference database entries could not be correlated to experimental peaks even though they lay just a tiny bit outside the range of experimental peaks (if the corresponding option "restrict to experimental range" was active).
    • The quantitative results from Rietveld refinement were not used (copied into Match!) in certain circumstances (e.g. if no experimental peaks were detected/present).
    • Several minor bugs have been fixed as well.
