This will provide your with a 3D numpy array of shape (n_epochs, n_channels, n_times). To get your events data, you can use the find_events function, which will return events: Returns: events : array, shape = (n_events, 3) All events that were found.

Weblabel starts with a known type (such as 'EEG') followed by a space and a name (such as 'Fp1'), the channel type will be set accordingly, and the channel will be renamed to the original label without the prefix. For unknown prefixes, the type will be 'EEG' and the name will not be modified. If False, do not infer types and assume all channels are of WebMy logic for parsing the data is as follows.. Each packet starts with the 2 byte sync sequence 165, 90. Followed by version number byte, then packet number byte and then the 6 channels of raw EEG data (2 bytes each) and finally 1 byte of button state. Which gives 17 bytes per packet.
