+# Probe Library Generator
+
+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:
+
+```bash
+# Activate the virtual environment
+source .venv/bin/activate
+
+# Install required packages (already done)
+pip install probeinterface numpy
+```
+
+## Usage
+
+### Process All Available Probes
+
+```bash
+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/` directory
+
+### Process Single Probe
+
+```bash
+python process_single_probe.py manufacturer probe_name
+```
+
+Examples:
+```bash
+python process_single_probe.py neuronexus A1x32-Poly3-10mm-50-177
+python process_single_probe.py cambridgeneurotech ASSY-37-E-1
+```
+
+### Discover Available Probes
+
+```bash
+python src/probe_library/discover_probes.py
+```
+
+This will test which probes are actually available in the probeinterface library.
+
+## Currently Available Probes
+
+Based on testing, these probes are available:
+
+- **neuronexus/A1x32-Poly3-10mm-50-177** - 32 contacts, 1 shank
+- **cambridgeneurotech/ASSY-37-E-1** - 32 contacts, 2 shanks
+- **cambridgeneurotech/ASSY-77-E-1** - 64 contacts, 4 shanks
+- **cambridgeneurotech/ASSY-156-P-1** - 64 contacts, 4 shanks
+- **cambridgeneurotech/ASSY-116-P-1** - 32 contacts, 2 shanks
+
+## Output Files
+
+All generated files are saved to the `probe_outputs/` directory:
+
+```
+probe_outputs/
+├── neuronexus_A1x32-Poly3-10mm-50-177.csv
+├── neuronexus_A1x32-Poly3-10mm-50-177.obj

+
+## Example Output
+
+### CSV File
+```csv
+electrode_number,x,y,z,width,height,depth
+1,0,450,0.0,20,20,20
+2,0,500,0.0,20,20,20
+3,0,400,0.0,20,20,20
+...
+```
+
+### Metadata JSON
+```json
+{
+  "name": "Neuronexus A1X32-Poly3-10Mm-50-177",
+  "type": 1,
+  "producer": "neuronexus",
+  "sites": 32,
+  "shanks": 1,
+  "references": "Generated using probeinterface library",
+  "spec": "https://probeinterface.readthedocs.io/"
+}
+```
+
+## Notes
+
+- Coordinates are in micrometers
+- The probe tip is at the origin (0,0,0)
+- OBJ files include both the probe shank and electrode contact geometry
+- The tool automatically handles 2D to 3D conversion for probes
+- SSL certificate verification is disabled to handle library download issues
+
+## Troubleshooting
+
+If you get SSL certificate errors, the scripts automatically handle this by disabling certificate verification for the probeinterface library downloads.
+
+If a specific probe isn't available, check the available probe list using the discovery script.
