You must first define the prefix for the output files in this data reduction session.

All files created during this session, including intermediate and final data files, plus a log file and various utility files, will have the same prefix.

You may choose your own prefix or use the default prefix.

Note that at this stage you may not change your output (''Working'') or your input ("raw data") directories. If you want to change the working directory you should click "Cancel'' to return to the main DAVE menu, and then select "File|Working directory".
Similarly select ''File|Raw data directory'' to change the raw data directory.
