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.","version":1,"lift":{"pass_rate_delta_pts":9.09,"pass_rate_pct":90.9,"total_cases":22,"passed_cases":20,"tokens_delta_pct":558.8,"turns_delta_pct":0,"verdict":"mixed","benchmark_model":"gemini-3.6-flash","grading_method":"judged","completed_at":"2026-08-24T11:17:01.102362+00:00"},"skill_score":0.9091,"benchmark_models":[{"model":"gemini-3.6-flash","headline":true,"delta_pts":9.09,"with_pass_pct":90.9,"without_pass_pct":81.8,"tokens_delta_pct":558.8,"turns_delta_pct":0,"total_cases":22,"cases_aggregated":22,"verdict":"mixed","never_hurt":true,"completed_at":"2026-08-24T11:17:01.102362+00:00","run_id":"513e2a1e-ef20-4dbe-8e54-d5f74c4a1c14","version_number":1,"is_latest_version":true,"gate":null}],"trust":{"skill_safety":"passed","safety_status":"clean","intent_verdict":"safe","content_status":"clean","indexable":true},"license":"BSD-3-Clause","install_count":0,"manifest_hash":"9af54c447c6e5708a40f0bbe063dd174595827a60323e11d359c57f70df3cee5","raw_url":"https://app.decimal.ai/s/jaechang-hits-trackpy-particle-tracking/SKILL.md","scorecard_url":"https://app.decimal.ai/skills/jaechang-hits-trackpy-particle-tracking"}
