   ==== UHDAS processing from scratch, using python ==============

(1) run

      adcptree.py  os75nb --datatype uhdas --cruisename at20


(2) change directories to ADCP processing directory just created

    cd  os75nb

(3)

   see "setup.txt" -- need to have a directory called "config"
   with a file called "at20_proc.py", tailored for this cruise.


(4) create a quick_adcp.py control file

    unix: this example  is written as a bash "heredoc" for
          cut-and-past ease, but you can create q_py.cnt with
          an editor to have the parts between (or including)
          the comments

cat << EOF > q_py.cnt

    ####----- begin q_py.cnt------------
    ## all lines after the first "#" sign are ignored
      --yearbase    2012
      --cruisename  at20   # used to identify configuration files
                              #  *must* match prefix of files in config dir

#      --update_gbin  ## NOTE: You must remake gbins for python processing if
                      ## - you are not sure
                      ## - if parameters for averaging changed
                      ## - various other reasons.
                      ## ==> just do it, and put them somewhere else
                      ##     (see next argument)

      --configtype python  ## python processing can read either type

      --use_uvship

      --sonar       os75nb
      --dbname      aship
      --datatype    uhdas
      --ens_len     300

      --ping_headcorr        ## applies heading correction.
                             ##     settings found in config files
      --proc_engine python   ## use python to do calculations

      --max_search_depth 1500    ## do not look for the bottom in open ocean

EOF


----------
(5) run quick_adcp.py:

        quick_adcp.py --cntfile q_py.cnt --auto

===================================================================
----------
(6) (a) check calibration:heading correction device:



    figview.py cal/rotate/*png

    conclude: no action needed


 (b) check calibration:

-------------------
(7)  edit "gautoedit" (go to "edit" directory with command line,
    type "gautoedit.py"

    # apply editing:


      cd ..
      quick_adcp.py --steps2rerun apply_edit:navsteps:calib --auto

    # check editing -- looks OK

          dataviewer.py


    - check calibrations again

==================================================================

    quick_adcp.py --steps2rerun rotate:apply_edit:navsteps:calib --rotate_amplitude 1.002 --rotate_angle 0.06 --auto
