What is neuropixels-analysis?

A workflow for analysing Neuropixels recordings, which are high-density measurements of electrical activity from many neurons. It uses SpikeInterface to load, clean, sort, measure, and curate neural recording data.

Use it with SpikeGLX, Open Ephys, or NWB recordings to filter data, correct drift, detect spikes, calculate quality metrics, and review sorted units.

It brings the stages from raw recordings to reviewed neuron units into one repeatable process. This reduces the need to assemble separate tools for preprocessing, spike sorting, and quality checks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00098	$0.04049
Opus 5	$0.00049	$0.02024
Sonnet 5	$0.00020	$0.00810
Haiku 4.5	$0.00010	$0.00405

Security

Grade A, and why

neuropixels-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 7 executable files (assets/analysis_template.py, scripts/compute_metrics.py, scripts/explore_recording.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Neuropixels Data Analysis

Overview

Toolkit for analyzing Neuropixels high-density neural recordings using current best practices from SpikeInterface, the Allen Institute, and the International Brain Laboratory (IBL). It covers the full workflow from raw data to publication-ready curated units.

All examples use the real SpikeInterface API (spikeinterface.full as si) plus the companion curation module (spikeinterface.curation as sc). The skill ships runnable scripts in scripts/ and a copy-and-edit template in assets/ that implement this workflow directly on top of SpikeInterface — there is no separate package to install beyond the dependencies listed under Installation.

When to Use This Skill

This skill should be used when:

Working with Neuropixels recordings (.ap.bin, .lf.bin, .meta files)
Loading data from SpikeGLX, Open Ephys, or NWB formats
Preprocessing neural recordings (filtering, common reference, bad-channel detection)
Detecting and correcting motion/drift
Running spike sorting (Kilosort4, SpykingCircus2, Mountainsort5, Tridesclous2)
Computing quality metrics (SNR, ISI violations, presence ratio, amplitude cutoff)
Curating units (threshold-based, model-based, or AI-assisted)
Creating visualizations and exporting to Phy or NWB

Supported Hardware & Formats

Probe	Electrodes	Channels	Notes
Neuropixels 1.0	960	384	Use `phase_shift` for ADC correction
Neuropixels 2.0 (single)	1280	384	Denser geometry
Neuropixels 2.0 (4-shank)	5120	384	Multi-region recording

Format	Extension	Reader
SpikeGLX	`.ap.bin`, `.lf.bin`, `.meta`	`si.read_spikeglx()`
Open Ephys	`.continuous`, `.oebin`	`si.read_openephys()`
NWB	`.nwb`	`si.read_nwb()`

Quick Start

Import and configure parallel processing

import spikeinterface.full as si

# Global job kwargs are reused by all parallelizable steps
si.set_global_job_kwargs(n_jobs=-1, chunk_duration="1s", progress_bar=True)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
