Example dataset demonstrating the BIDS Extension Proposal for Microelectrode Electrophysiology (BEP032) format for multi-electrode array recordings from non-human primates.

The Utah arrays have two Pt/Au reference wires physically separate from the 96 recording electrodes, placed under the dura rather than at grid positions.
- sub-i: Standard configuration with corners (1, 10, 91, 100) unconnected. Reference wires assigned to corners 1 and 100.
- sub-l: Custom configuration with all corners connected. Unconnected positions at 80, 90, 93, 95. Reference wire coordinates set to n/a (no available grid positions).
