UTide

Python re-implementation of the Matlab package UTide.

Still in heavy development--everything is subject to change!

Note: the user interface differs from the Matlab version, so consult the Python function docstrings to see how to specify parameters. Some functionality from the Matlab version is not yet available.

Installation

Download the zip file and unzip it; or, much better, clone the git repository. In either case, change your directory to the newly-created utide distribution directory.

python setup.py install

or

python setup.py install --user

if you don't want a system-wide installation.

If you want to work on developing the package, then

python setup.py develop

will allow you to test without reinstalling after making a modification.

Another option is to use

pip install .

If you are using conda and will not be developing the code, you can install from the IOOS channel. See https://github.com/ioos/conda-recipes/wiki.

The public functions can be imported using

from utide import solve, reconstruct

To test and make sure that the package has been installed and imported correctly, run:

from utide.tests.test_solve import test_roundtrip
test_roundtrip()

If you have the pytest package installed, you can execute python setup.py test from within the source directory to run all tests.

A sample call would be

from utide import solve

coef = solve(time, time_series_u, time_series_v,
             lat=30,
             nodal=False,
             trend=False,
             method='ols',
             conf_int='linear',
             Rayleigh_min=0.95,)
