Match! Update Page

Latest Update

In order to make sure that your Match! software is always "up-to-date", you should visit this page from time to time, especially if you have deactivated the "Automatic Online Update" option.

The current version is 3.2.1 released May 24, 2016.

If you are still using an earlier version (which can be checked by selecting "About Match!" from the "Help" menu), we strongly recommend to update to the current version. This can easily be achieved by performing the following steps:

  1. If Match! is running, please save any open documents and close the program.
  2. Please DO NOT uninstall the previous version before installing the new version! Instead, simply install the new version on top of the existing version. This is important to make sure that your license file is retained.
  3. Download the installer file for your platform (Windows, Mac OS X, Linux 32-bit and 64-bit) from the Download page, and uncompress ("unzip") it if necessary.
  4. Make sure that you have administrator privileges on multi-user systems, then run the installer by double-clicking on it. More details about this topic are given in the platform-specific "Readme" files that are also available from the Download page.
  5. Follow the steps in the installer until it has finished, then restart Match!.
  6. Check whether the update was successful by selecting "About Match!" from the "Help" menu.

Enhancements in version 3.2.1

  • The initial dialog asking a new user to select the path to his FullProf installation is now displayed later on (if required) when the user wants to run a Rietveld refinement calculation for the first time.
  • The header of the "intensity" column in the peak list now gives the exact type of values ("Peak height" or "Integrated intensity"), depending on the scaling of the y-axis in the pattern graphics as "relative intensities (I rel.)" (peak heights scaled to a maximum 1000.0) or "Counts" (-> integrated peak intensities)).
  • In the Match list, quantitative amounts of phases for which the default I/Ic-value had to be used (because the corresponding entries did not contain a I/Ic-value), are now displayed in red color (instead of the former '(*)' indicator that was used up to now).
  • Several bugs have been fixed:
    • Some intensity scaling issues in the pattern graphics have been resolved.
    • A bug affecting the command "File/Print/Data sheet" has been fixed.
    • The sorting of the Match list according to the quantitative amounts did not work properly if the default I/Ic-value of 1.0 was used for at least one of the phases.
    • In certain circumstances, Match! was unable to find the "Diamond" program on Windows PCs.
    • Some minor bugs have been fixed as well.

Enhancements in version 3.2.0

  • 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.

Enhancements in version 3.1.1

  • New command "Peak list options..." in context menu of peak list (right-click to open)
  • Command "Internal standard" has been added to context menu of Match list (right-click to open)
  • Several bugs have been fixed:
    • A bug prohibiting the usage of PDF-2 databases released before 2011 (causing error messages like 'Cannot append to Match! protocol file " (tbl_Cellpar)') has been fixed.
    • Another issue due to which no space group information was given in the data sheets of some PDF-entries has been resolved.
    • The problem that the setting of the raw data processing options "Geometry" and "Omega" could not be saved as default has been resolved.
    • In the User Database Manager, several bugs have been fixed.

Enhancements in version 3.1.0

  • You can now edit or delete reference database entries marked in the candidate list (not possible for ICDD PDF database entries though).
  • New version of COD reference database
  • It is now possible to use entries even in non-standard settings for Rietveld refinement, provided that the corresponding space group symmetry data are present in Match!.
  • New command "Edit background" in the "Pattern" menu (shortcut )
  • You can now edit the sample IDs of additional patterns by using the corresponding new command from the pattern menus.
  • The commands "Edit/Sample ID" und "Edit/Sample Date/Time" have been moved from the "Edit" into the "Pattern" menu.
  • When importing automatic divergence slit (ADS) data, the user is now asked if he would like to convert them in fixed slit data (FDS).
  • Several bugs have been fixed:
    • A bug affecting the usage of the preferred orientation vector in Rietveld refinement calculations (vector given in Parameter Turn-On dialog was not used in FullProf script) has been resolved.
    • Two bugs affecting the keeping of reference databases while resetting Match! to its factory settings have been fixed.
    • An issue causing the displaying/reading of wrong entry data in large COD- or user reference databases has been fixed.
    • A bug causing e.g. export problems if 2 byte characters were present in the file name/path has been fixed.
    • If peak parameters were edited in the peak list during a search-match calculation that was run automatically after another peak had been edited, the program crashed.
    • Some minor bugs have been fixed as well.

Enhancements in version 3.0.3

  • Several bugs have been fixed:
    • A bug causing the "Quality" selection criteria on the "Restraints/Properties" and "Additional entries/Properties" tabs not being available has been fixed.
    • Sometimes Match! crashed during Rietveld refinement calculations if FullProf wrote "********" sequences into the result files due to overflow.
    • Due to a bug, the sign of the zero point correction changed if a Rietveld refinement did not converge or if FullProf script files were exported from the "Rietveld Parameter Turn-On"-dialog.
    • The unit of pressure in the data sheets was given as "GPa" instead of "kPa".
    • The font in the "Rietveld variable modificaton" dialogs was too large so that sometimes the explanations did not fit in completely.
    • A bug causing a modification of the default paper size when printing the pattern graphics has been fixed.
    • Some minor bugs have been fixed as well.

Enhancements in version 3.0.2

  • The peak searching algorithm has been slightly improved.
  • Automatic divergence slit data are automatically converted into fixed slit data if corresponding diffraction data are imported from XRDML-files.
  • Several bugs have been fixed:
    • Undo/redo sometimes caused unexpected results if zooming or tracking operations were performed before.
    • Due to a bug it was no longer possible to zoom in by double-clicking in the diffraction pattern.
    • A bug has been fixed that caused a problem in background calculation if the maximum intensity value of the profile data was below 5.0.
    • Some minor bugs have been fixed as well.

Enhancements in version 3.0.1

  • An import interpreter for TXRD export text files has been implemented.
  • The direction of the mouse wheel zoom has been reversed.
  • Several bugs have been fixed:
    • If a "mixed" wavelength like Cu K-alpha was used, the Miller indices (hkl) were not displayed in the pattern graphics.
    • A bug causing the default wavelength not to be applied when Match! has just been started has been fixed.
    • Peak correlations in the pattern graphics could be mixed up due to a correponding bug.
    • A bug in the peak searching code sometimes causing peaks to be not detected has been fixed.
    • A bug preventing Match! batch script files (*.mbf) from being run has been fixed.
    • The value of the FullProf parameter Cthm (monochromator polarisation correction) has been corrected.
    • Some library files were missing in the Linux installers.
    • Some minor bugs have been fixed.

Enhancements in version 3.0.0

  • New entries can now be added to the reference database straight away, without using the User Database Manager or the need to create new index files in the Reference Database Library. The new entry data can be imported from a cif-file and/or edited manually.
  • User-configurable automatic Rietveld refinement: Parameter sequence sets for up to 10 subsequent refinements can easily be created, stored and recalled later on.
  • New user level "Rietveld" that runs all steps automatically, incl. identification of the matching phases and Rietveld refinement. All the user has to do is to select the raw diffraction data file to be analyzed and wait a few seconds until the phase analysis report is displayed.
  • New specimen-displacement correction for asymmetric geometry
  • New toolbar button for "Batch" processing options
  • Order of buttons in the "Search-Match/Select entries/FullProf" toolbar has been rearranged so that it is now more logical from left to right.
