What are epochs in MNE?
The mne.
Epochs objects are a way of representing continuous data as a collection of time-locked trials, stored in an array of shape (n_events, n_channels, n_times) .
How do you plot epochs?
Plotting Epochs as an image map
A convenient way to visualize many epochs simultaneously is to plot them as an image map, with each row of pixels in the image representing a single epoch, the horizontal axis representing time, and each pixel's color representing the signal value at that time sample for that epoch.
What is an epoch in EEG?
EEG epoching is a procedure in which specific time-windows are extracted from the continuous EEG signal. These time windows are called “epochs”, and usually are time-locked with respect an event e.g. a visual stimulus.
How to use MNE in Python?
If you only need 2D plotting capabilities with MNE-Python (i.e., most EEG/ERP or other sensor-level analyses), you can install all you need by running pip install mne in a terminal window (on Windows, use the “Anaconda Prompt” from the Start menu, or the “CMD.exe prompt” from within the Anaconda Navigator GUI).
