ADCP Tools Version 4.0 - Frequently Asked Questions

Topics

Where can I find the old ADCP tools for MATLAB 4.0? 
Rdi2cdf doesn't work. 
Will rdi2cdf.m work on my narrowband data? 
Beam to earth conversions do not exactly match BBLIST output. 
Where is my bottom ping data?
How accurate is the Beam to Earth rotation?
What versions of MATLAB will the ADCP Toolbox work with?

Are you on a Sun workstation?  Rodolphe Rousselet (rous@shom.fr) of EPSHOM - France has contributed a patch that should eliminate fread problems on Sun workstations, download my_fread.m, a new version of fread.m. 

No. However, there are enough narrowband users out there who seem to like this concept that I have already heard from some folks interested in porting the code. Let me know if you want to help, and can put everyone in touch with one another.

For data recorded in beam format: The beam2earth function does not yet include transducer and compass calibration adjustments. The conversion from beam to earth agrees within 1.18 mm/s with BBLIST output.

If your data was recorded in earth coordinates, you have nothing to worry about (if the compass and tilt sensors did their jobs well).

Since this code is written for bottom mounted, long term, time-series measurements, bottom ping data is ignored. The code doesn't seem to choke on data with bottom pings, but since my work is always self contained, I can't be sure. Perhaps someone can help out with this?

Accurate enough to provide a general idea if the instrument is working correctly.  I would not recommend using it for scientific analysis at this time because it does not use beam mapping and does not make use of the transducer calibration matrix.

The ADCP Toolbox does not work well with MATLAB version 5.1 or 5.0. The problem appears to be with the batch.m command. If the batch.m command was removed from the code, it may work, but we do not support it.

The good news is that the ADCP Toolbox does work with the newest release of MATLAB version 6.0.
