function 't_get18consts' not defined

[carocamargo]

I'm trying to use ttide, and I have a time series that is longer than a year. I then get this error:

---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)

---> 56     const, sat, cshallow = t_get18consts(centraltime)
     58     ju = np.array([range(2,
     59                          (max(const['freq'].shape) + 1))]).reshape(1, -1).T
     60     # Skip Z0

NameError: name 't_get18consts' is not defined

If I slice the time series in yearly periods, I have no issue.

The same problem, is there a solution?

[carocamargo]

I changed packages instead of trying to find a solution...utide works fine with long records (https://github.com/wesleybowman/UTide)

Thanks, I'll try it!

Do you have matlab code
