how do i change the amplitude of my raw data signal?
I’m having great difficulty! My signal is clipping because amplitude is too high but I can’t find instructions on the website to do this.
Raw.plot() accepts a
scalings parameter. According to the documentation, this value defaults to:
dict(mag=1e-12, grad=4e-11, eeg=20e-6, eog=150e-6, ecg=5e-4, emg=1e-3, ref_meg=1e-12, misc=1e-3, stim=1, resp=1, chpi=1e-4, whitened=1e2)
You can pass your own values here instead.
thanks for the feedback! how to reduce this amplitude using the annotations function?
I’m not sure what you mean? Annotations have nothing to do with signal amplitude…
Yes I know. I want to reduce amplitude to better visualize my tags.
can you show me an example of how I can reduce the amplitude applied to the plot? Because I really don’t understand how! I’m a beginner and I get very confused!
And I don’t find didactic information for those starting from scratch.
And in this role?
Like I said, pass
to accommodate for signal amplitudes of up to 500 µV.
Also note that you can change the scaling in an already-opened plotting window by pressing the + and - keys. Click on the Help button to see the available keyboard shortcuts.
