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 epochs 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).
