How do I get set up?

To avoid problems with installation, use of the virtualenv Python virtual environment is recommended.

Then use pip to install all dependencies (numpy, scipy, matplotlib, netCDF4, pyproj, ...), e.g.:

pip install numpy scipy netCDF4 matplotlib opencv-python pyyaml pyproj pint polygon3

Then run the following to install the eddy tracker:

python setup.py install

Two executables are now available in your PATH: EddyIdentification and EddyTracking

Edit the corresponding yaml files and then run the code, e.g.:

EddyId share/nrt_global_allsat_phy_l4_20190223_20190226.nc 20190223 adt ugos vgos longitude latitude ./ -v INFO

for identification, followed by:

EddyTracking tracking.yaml

for tracking.
