###

Display SPEC data

PyMCA can display SPEC shared memory arrays.
Just select File-Open-SPS and select the name of the SPEC session you're interested on. Then select the array to display and the columns or rows to be displayed. You can also do that selecting the SPS tab of the source selection widget.

###

Display Specfile format data

Select File-Open-Specfile (or select the Specfile tab of the source selection widget) and browse your directories for the desired file. A list of scans will be presented showing the number of points and the number of MCAs in each of them. To select a scan just click on it. If it contains just one MCA you can then click the ADD button to add that MCA to the MCA graphics window. If it contains several MCA you will have to select the MCA tab and select the different MCAs to be plotted (click, CTRL-Click and Shift-Click supported) then click on ADD, REMOVE, REPLACE depending on the desired operation. Specfile SCAN data can be shown on the SCAN window. To do so, select the SCAN tab, select the x counter, the y(s) counters and click ADD.

###

Display ESRF Data Format (EDF) Files

Select File-Open-Edffile (or select the Edffile tab of the source selection widget) and browse your directories for the desired file. The first image of the file will be presented. Horizontal or Vertical selections can be made either a) clicking on the image or b) selecting the appropriate row or column on the bottom combo selection boxes and clicking the ADD, REMOVE, REPLACE buttons.

Multiple image EDF files are supported. Just select the appropriate image in the combo box.

Display Raw ASCII data

Single MCA raw ASCII data are handled in the same way as Specfile format files. Please refer to the Display Specfile information.
