How to solve this error?? #110

Open vitarfast opened 4 years ago

vitarfast commented 4 years ago

hi, i'm planning to use a neurokit example. But I am not able to follow the example due to an error. How can I fix it? I changed the scikit-learn version 0.23.2 to 0.20.1 to fix the error, but error was still existed.

Please look at below code and error message.

Import packages

import neurokit as nk import pandas as pd import numpy as np import seaborn as sns

Download data

df = pd.read_csv("https://raw.githubusercontent.com/neuropsychology/NeuroKit.py/master/examples/Bio/bio_100Hz.csv")

Plot it

df.plot()

Process the signals

bio = nk.bio_process(ecg=df['ECG'], rsp=df['RSP'], eda=df['EDA'], add=df['Photosensor'], sampling_rate=100)

bio = nk.bio_process(df["ECG"], df["RSP"], df["EDA"], df["Photosensor"], sampling_rate=100)

Plot the processed dataframe, normalizing all variables for viewing purpose

nk.z_score[bio['df']].plot()

ValueError: Digital filter critical frequencies must be 0 < Wn < 1

Hi @vitarfast, I'd suggest using NeuroKit2 as this one is not maintained anymore. Find more info at https://github.com/neuropsychology/NeuroKit
