trackpy (Claude Skill)

Python library for single-particle tracking (SPT) in video microscopy via the Crocker-Grier algorithm.


Type	Claude Skill
Supplier	jaechang-hits (community OSS, CC BY 4.0)
Availability	GA — part of the BixBench-evaluated SciAgent-Skills collection
Pricing	Free / OSS (BSD-3-Clause)
Capabilities	Read/Write — Claude runs the skill’s Python locally (Bash), not as an MCP tool

How to install

SciAgent-Skills is not an npm package — skills are plain markdown read directly by the agent (no npx/npm).

Claude Code — clone and load as a plugin:
```
git clone https://github.com/jaechang-hits/SciAgent-Skills
```
Then inside Claude Code run /plugin install sciagent-skills (verify it appears under /plugin → Installed). Clone into your project directory so Claude Code picks the skills up via CLAUDE.md.
Manual / other agents — point the agent at the skill file directly:
```
cp -r SciAgent-Skills/skills/cell-biology/trackpy-particle-tracking ~/.claude/skills/
```
The skill declares its own Python dependencies in its SKILL.md; install them when prompted on first use.

What it does

Python library for single-particle tracking (SPT) in video microscopy via the Crocker-Grier algorithm. Locate particles (fluorescent spots, colloids, vesicles, cells) per frame, link into trajectories, filter short tracks, and compute MSD for diffusion analysis. 2D/3D with subpixel accuracy; reads TIF stacks, AVI, image series via pims. Use for quantitative SPT and diffusion coefficient extraction from fluorescence or brightfield video.

Primary use cases: quantitative SPT and diffusion coefficient extraction from fluorescence or brightfield video.

Notes

Distributed as a SKILL.md (plus code examples) in the SciAgent-Skills collection — Claude executes it locally via Bash/Python rather than as an MCP server. Upstream license: BSD-3-Clause. The skill directory upstream is skills/cell-biology/trackpy-particle-tracking.
