    (for example, no frills)
    WARNINGS:
      - You must have gyro heading coming directly into your deck unit
              or this won't work.  Advise using ENX data instead
      - This is essentially the same as ENX except that
              (1) it uses the gyro heading
              (2) you must know the heading alignment of the transducer
              (3) you must know the transducer depth
      - Find the transducer depth and the transducer angle (use
              'read' in matlab to find them from the LTA or STA data)

    To process ENS (single-ping, beam coordinates) data with 300-second
    averages,  Ocean Surveyor data, "nb" pings

    (1) run
             adcptree.py vg0404 --datatype ens

    (2) change directories to vg0404/ping and link or copy the LTA files here
    (3) then "cd .." to get back to  the cruise directory.
    (4) Now: (note that the averaging step ('load') may take several hours..)

    quick_adcp.py --yearbase 2004  --dbname a0404  \
    --ducer_depth 7  --ens_halign 45 \
    --datatype ens --instclass os --pingtype nb  --datafile_glob "*.ENS"

    and to recalibrate: (example with angle correction 1.3)

    quick_adcp.py --yearbase 2003  --rotate_angle 1.3  \
    --steps2rerun rotate:navsteps:calib

    and after editing,

    quick_adcp.py --yearbase 2003 --instname os38 \
    --steps2rerun apply_edit:navsteps:calib:matfiles --auto




 NOTE to Windows users:
         make sure your PATH includes the location of quick_adcp.py
         make sure your PYTHONPATH is set correctly
         make sure you associate *.py extensions with the python program
