### POST-PROCESSING -----------------------------------------------------------------------------


  cd os75nb
  plot_nav.py nav/a_fk.gps

Just two small segments (the first with half day of duration and the second with one day) of data in a cruise from Apia, Samoa to Honolulu, HI.


(1) review the data


    (a) check calibration:heading correction device:

             figview.py cal/rotate/*png

              conclude: no action needed

        figview.py .

    (b) check calibration:

# No calibration available for this cruise.


   (c) look at the data:

              dataviewer.py


(2)  edit "gautoedit"

    cd edit
    gautoedit.py -n5


    # apply editing:


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

    # check editing -- looks OK

          dataviewer.py



figview.py  cal/watertrk/wtcal1.png

(3) make web plots

       quick_web.py --interactive

 - view with a browser, look at webpy/index.html


(4) Extract data:

   quick_adcp.py --steps2rerun matfiles --auto

 You can extract NetCDF files as well.

   adcp_nc.py         adcpdb  contour/os75nb_short FK171224 os75nb
   adcp_nc.py  --long adcpdb  contour/os75nb_long  FK171224 os75nb

 To check netcdf file:

   ncdump -h contour/os75nb_short.nc
