Probe Library

This tool uses probeinterface to generate CSV and OBJ files for neural probes that are compatible with Pinpoint.

Files Generated

For each probe, the tool generates:

1. CSV file - Electrode positions and dimensions (probe_name.csv)
2. OBJ file - 3D geometry of the probe (probe_name.obj)
3. Metadata JSON - Probe specifications (probe_name_metadata.json)

CSV Format

The CSV file contains electrode information with these columns:

• electrode_number: 1-based electrode number
• x, y, z: Electrode position relative to probe tip (micrometers)
• width, height, depth: Electrode dimensions (micrometers)

Installation

Make sure you have the virtual environment set up:

# Activate the virtual environment
source .venv/bin/activate

# Install required packages (already done)
pip install probeinterface numpy

Usage

Process All Available Probes

python src/probe_library/probe_generator.py

This will:

• Try to load all known probes from the probeinterface library
• Generate demo probes (linear, multi-column, dummy)
• Save all files to probe_outputs/<manufacturer>/<probe_name> directory

Notes

• Coordinates are in micrometers
• The origin (0,0,0) is the bottom/left corner of the bottom/left-most electrode
