Before you start

If you are working with a new dataset, pick an appropriate deployment id for your dataset [Note]It is a good idea to keep to the naming convention defined here because it will help you avoid naming your data the same as a dataset from another researcher. It will also make it easier to search for the data in archives. Unfortunately, we have not been very strict in the past about whether the species initials are taken from the Latin binomial (which is preferred) or the common name. So, there is DTAG data from sperm whales that is labelled 'pm' and 'sw'. Please use the Latin binomial unless there is a compelling reason not to.. Typically, you should follow the standard DTAG protocol of 2-letter Latin or common species initials, 2-digit year, underscore, 3-digit Julian day of year, 1-letter animal of the day, e.g.:

depid = 'mn17_283b';

To find out the Julian day for a given date, use:

julian_day([2018,7,5]) % find out julian day number of 5th July 2018

Download the latest Matlab/Octave tools for the tags from the D4 Google Drive. You need both animaltags.zip and d3matlab.zip [Note]The DTAG 4 uses the same tools as the DTAG 3 except in a few cases. All of the tools for both versions of the tag are in d3matlab.zip. These tools should work equally well in Octave (if you discover any that do not, please email us with details)..

Unzip these files and add the resulting directories (with subfolders) to the Matlab/Octave path. You can do this with a pull-down menu option, or you can enter pathtool in the command window to access the same dialog box. Remember to save the path (with the button at the bottom of the dialog box) once you have added the tag tools directories.
