Error

[ghost]

Hi, I installed waipy from github, exactly the way you have described. (NO PIP)
So I execute
result = waipy.cwt(data_norm, 1, 1, 0.25, 2, 4/0.25, alpha, 6, mother='Morlet')
and i get following error

IndexError Traceback (most recent call last)

I did as the suggestion, but it still did't work and got the wrong info! what should I do ?

I modify the "axis=1" with "axis=0" ( lib_wavelet.py and wavetest.py), just get the following warning. Besides, I can run the example(https://wavelet-analysis.readthedocs.io/en/latest/cookbook.html) successfully, and plot the data nino3. (the graph attachment https://www.dropbox.com/s/o861f36bxi67306/figure_1.png?dl=0 )

Hi Gavin

Did you try the example1?

open a terminal:

git clone https://github.com/mabelcalim/waipy.git

cd waipy/

sudo python setup.py install

python

import waipy

import numpy as np

import matplotlib.pyplot as pet

import pylab

z = np.linspace(0,2048,2048)

x = np.sin(50_np.pi_z)

y = np.cos(50_np.pi_z)

data_norm = waipy.normalize(x)

result = waipy.cwt(data_norm, 1, 1, 0.125, 2, 4/0.125, 0.72,
6,mother='Morlet',name='x')

waipy.wavelet_plot('Sine', z, data_norm, 0.03125, result)

pylab.show()

data_norm1 = waipy.normalize(y)

result1 = waipy.cwt(data_norm1, 1, 1, 0.125, 2, 4/0.125, 0.72, 6,

... mother='Morlet',name='y')

waipy.wavelet_plot('Cosine', z, data_norm1, 0.03125, result1)

pylab.show()

cross_power, coherence, phase_angle = waipy.cross_wavelet(result['wa
ve'],

...
result1['wave'])

waipy.plot_cross('Crosspower sine and cosine', cross_power, phase_angle,

... z, result, result1)

pylab.show()

I didn't have time to fix all the examples in github.

Please, check if the example n.1 it's working on your machine.

regards
Mabel

Hi Gavin,

Can you explain better which axis did you modified?
In wavetest.py you do not suppose to change the axis :

global_ws = variance * (np.sum(power.conj().transpose(), axis=0) / n)
this means that the conjugate power is transpose in the first dimension =
axis =0

joint_wavelet = np.concatenate((np.fft.ifft(ondaleta)[np.ceil( n / 2.):],
np.fft.ifft(ondaleta)[np.ceil(n / 2.):][::-1]), axis=1)
this means that I need to concatenate the significant values in the second
dimension = axis =1

Regards
Mabel

Hi!
Yesterday I converted waipy to python3.6. Now it's waipy0.0.1.0!
Try to check the example_python3.6 on my github (https://github.com/mabelcalim/waipy)

I hardly recommend to install from github:
in your path:
git clone https://github.com/mabelcalim/waipy.git
cd waipy
python3 setup.py install

And try to use the example ;)
If you have some problem to install, please let me know!

Thanks for choosing waipy!
Best regards
Mabel

Hi,am running this code:
result = waipy.cwt(data_norm, 1, 1, 0.125, 2, 4/0.125, 0.72,
6,mother='Morlet',name='x')
and getting the AxisError below:

AxisError: axis 1 is out of bounds for array of dimension 1

Kindly help to solve it
