+# Reach-to-Grasp Multi-electrode Array Recordings (BEP032 Example)
+
+Example dataset demonstrating the **BIDS Extension Proposal for Microelectrode Electrophysiology (BEP032)** format for multi-electrode array recordings from non-human primates.
+
+## Source
+
+Converted from the Reach-to-Grasp dataset: https://gin.g-node.org/INT/multielectrode_grasp
+DOI: [10.12751/g-node.f83565](https://doi.org/10.12751/g-node.f83565)
+
+## Electrode Configuration Notes
+
+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).
