Software: Chooch
Home › Facilities › Computer Resources › Software › Chooch
The chooch software package is available to calculate the inflection and peak energies from a fluorescence scan on BMD or IDB. Before this can be done, the raw data file (kbscan_0102* type of file) for the energy scan needs to be accessible from any of the SGI or Linux computers. This file is stored in the Linux control computer's home directory. The most convenient way of running Chooch is to open a new xterm on the Linux control computer (bm14d4 or id14b4) and run "kb2ch". The kb2ch program will prompt you for the input and output file names and should generate an output file which is suitable for Chooch. A Chooch manual (PDF) is also available.
Chooch can be started from the command line by typing:
chooch <element> <edge> <filenameroot>
• element - two letter atomic symbol (case insensitive)
• edge - absorption edge ( K | L1 | L2 | L3 | M )
• filenameroot - trunk of raw data file e.g. for a raw datafile called SeMet.raw use SeMet
The data files that get generated can be copied to your directory on /data when you are finished.
A few example files were provided with the program:
Cutest.raw | PtL2.raw | Pttest.raw | SeFoil.raw | SeMet.raw
The data can either be cut from these web pages and pasted into a new file or they can be found on the SGI's in the /usr/local/Chooch-4.01/examples directory.
Please contact the staff if you have any questions.
