If your data conforms to the directory naming convention for the instrument, setting up the pipeline is fairly trivial.
Select your instrument from the list box to the left hand side of the application main window and then enter the UT date of the observations you are reducing into the entry field in the center of the main window. The raw and reduced data paths should now be set correctly. Enter the range of frame numbers that you are interested in into the List text entry and push the Start ORAC-DR button. The pipeline should initalise and start processing you data immediately.
A more detailed description of the Xoracdr user interface follows for
those people who need to do something slightly out of the ordinary,
although the interface itself should be fairly self explanatory for
those people used to the oracdr command line interface.
