Spike groups

Spike groups are typically defined by the group of channels within shanks. Channels are listed and comma-separated and labels can further be assigned to each group. Channels are 0-indexed.

Group	Channels	Label
1	51, 58, 52, 57, 49, 60, 50, 59, 54, 55, 53, 56
2	63, 38, 64, 39, 61, 41, 62, 42, 33, 37, 34, 35
3	47, 17, 46, 20, 45, 19, 43, 21, 48, 18, 44, 22
4	28, 1, 25, 2, 23, 3, 24, 4, 27, 31, 29, 32
5	8, 13, 7, 14, 6, 15, 5, 16, 9, 12, 10, 11
6	30, 36, 26, 40

This section is dedicated to extra inputs besides the primary recording channels. For extracellular recordings this includes any extra analog and digital channels. Further it can be inputs saved with an Arduino or Raspberry pi or an entirely different hardware solution.

Brain regions are defined according to the Allen Institute Atlas. A brain region can be assigned to a list of channels or spike groups.
