UHDAS raw (logged) data:
------------------------

For a ship with an NB150 and an OS38 (for example) 
in the **raw** subdirectory, 


ADCP data
~~~~~~~~~~

Directories with instrument names (such as nb150 or os38) contain:
    
    - \*.raw (binary files with ADCP data) 
    - \*.log (ascii file with time stamps that match each ping)
 
The raw instrument files are ready to be loaded into Matlab using an
overloaded methods read function in your path if you run **radcppath.m**
(must specify instrument and logging program).  Type **help read** in Matlab
for more info.

Serial ascii data:
~~~~~~~~~~~~~~~~~~
For example gpsnav, gyro, posmv, ashtech, soundspeed.

All files are ascii, and contain alternating time stamps and messages:

::

    $UNIXD, (time stamps)
    $NMEA,ascii NMEA message


For instruments that send multiple messages, there should be a Unix
time stamp for every message, e.g., for the Ashtech there should be:

- $UNIXD ...
- $PASHR,ATT ...
- $UNIXD  ...
- $GPGGA ...
