DNS Reduction - Paths Tab

In this tab, a user sets the path to the data files for processing, as well as to the locations where the output files will be stored. The Data Directory field is mandatory, and the user should browse to the location where the data files are located. If Automatically Set Other Directories checkbox is selected, the paths for PSD and Standard Files directories will be automatically set to default values. The folders for the processed files and generated reduction scripts will be set to default values, as well. Once a DNS data file is found in the Data Directory, the proposal number and username will be automatically displayed (if available) in the corresponding fields.

If the GUI is called from command line, the current working directory is automatically chosen as the Data Directory.

Main Controls Summary

Data Directory	Path to DNS .d_dat files
PSD Directory	Path to the position sensitive detector event list mode (.mdat files, not used at the moment)
Script Directory	Path to the directory in which python reduction scripts will be saved
Standard Files Directory	Path to the DNS calibration files (normally Vanadium, NiCr and Empty)
Export Directory	Path to the directory in which the processed data are saved (in the chosen formats)

In order to speed up the performance of data processing, the list of files that are contained in the Data Directory is cached to the file named last_filelist.txt. In order to clean up the cache, click on the Clear Cached button.

Whenever the user operates regularly with the same set of input/output directories, it might be convenient to save the corresponding configuration of input/output folders to an .xml file. This can be done by clicking on the “File” → “Save As” buttons in the top left corner of the GUI. After the configuration has been saved, it can simply be loaded by chosing “File” → “Open” → config_filename.xml.
