To feed the data to our models the way the data is handled has to change, since we need to separate it in the chunks of data containing the stimuli. Further looking into how the data is captured has to be done. See C. Guger et al., How many people are able to control a P300-based brain–computer interface (BCI)?, Neuroscience Letters 462 (2009) 94–98

Apparently the paper refers to channel 10 being the number of row/column flashing (from 1 to 12 since there are 6 rows and 6 columns) but I have found numbers going up to 30 or more on that channel.

The two first subjects could be using the Single Character paradigm, giving that labels from 1 to 36. I have taken those subjects out of the data we use.
