Improve PSD

2

Why this so nice: ```python import neurokit2 as nk import mne raw.plot_psd(fmin=0, fmax=40., picks=["EEG 050"]) ```  And ours so ugly 🥲 ```python channel = nk.mne_channel_extract(raw, what=["EEG 050"]).values psd =...

'No R-peak detected' is not handled in ecg_quality

5

### Description of the bug Using ecg.ecg_quality, the function `ecg.ecg_findpeaks` is used. It works well for all signals but for a really noisy signal (hand-crafted signal using ecg.ecg_simulate, with artificial...

Strategies for denoising ECG signal recorded in MRI settings

1

### After several exchanges between well-minded researchers working with biosignals, I come with a concrete suggestion to merge forces Since I started my master's, I've been wanting to increase accessibility...

nk.ecg_quality loop #ECG

6

**Question and context** I have 48 hours ECG data; there are many motion artifacts. I planned nk.ecg_quality loop, long term calculation can not detect motion artifact. So I tried to...

Allow linear_drift to undulate (or at least not always be upwards)

1

**Describe the solution you'd like** The `signal_distort` function is great. One limitation is that the `linear_drift` option will only ever cause the signal amplitude to [go upwards over time](https://github.com/neuropsychology/NeuroKit/blob/c1104386655724a5c624e740abf651c939fc5e48/neurokit2/signal/signal_distort.py#L143). **How...

Breathmetrics breath simulation is for flow not for belt/RIP signal and make function accessible

1

Two issues (first more of a feature suggestion, second more a problem) ### 1. Currently this function: https://neurokit2.readthedocs.io/en/latest/_modules/neurokit2/rsp/rsp_simulate.html#rsp_simulate Has a method called "breathmetrics" which calls a function with particular parameters....
