Direct Access to ADCP data
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


The following mechanisms exist for directly accessing data (into a program)

- **CODAS database** can only be directly accessed with Python.
  For Matlab access, one must `extract <../EXTRACTING/index.html>`_
  files to the disk, and then `read <../READING/index.html>`_
  the files.

- **raw ADCP data** can be accessed by both Matlab and Python.
