About CMPR
CMPR is a free multipurpose program for powder diffraction data.
11-BM staff routinely use it to examine & compare (CoMPaRe) powder XRD data at the beamline. It is a great too for manipulating and converting multiple datasets, and can also be used to fit or index diffraction peaks.
The program works well with 11-BM's .fxye GSAS format, but can be used with nearly any powder XRD data.
See the CMPR subversion page for download links, installation notes, and full documentation. ( https://subversion.xor.aps.anl.gov/trac/CMPR/wiki)
Getting Started
CMPR Windows
CMPR launches 2 windows: the main GUI Control window and the Plotting window.
Functions on the Control window are organized into multiple menu tabs. The Read file tab is highlighted below. You may need to expand the GUI window to see all tabs at once.
Left-click with a mouse in the Plot window to define a zoom window, right-click to un-zoom. The key "L" shows/hides a cursor mode to read values from the plot window.
Opening files
On the Read tab, first select the file format to be read (1). More formats can be found by scrolling down (red arrow). Navigate to the desired folder or directory (2). Select (hightlight) the file or files to be read (3). Click READ (4) to open the file(s).
Successfully opened files will be listed in the "Datasets Read" panel (1) and will appear in the plot window (2).
