!! File structure
My file structure for reducing MIDI files is:
* [@/disk1/burtscher/MIDIDATA/YYYY-MM-DD/@]: This is the place for all raw files at YYYY-MM-DD. Note that it is handy if you are able to write in this directory as you can then use [@midiguis()@] that writes an index of all files in the directory and is much faster than [@midigui()@] that doesn't need write permission in the midi raw files directory.
* [@/disk1/burtscher/reduceddata/YYYY-MM-DD/yyyy-mm-dd/@]: This is the place where I save all data I reduced on yyyy-mm-dd for the observation that took place on YYYY-MM-DD. Within this directory I use tags such as [@1365sci@], [@1365cal@] etc.

!! Typical data reduction process (verbose comments!)
