dipy-tool SKILL.md skillA

dipy-tool from cuhk-aim-group/neurodiscovery is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add cuhk-aim-group/neurodiscovery/dipy-tool@git:20260506.86420c0

Pins git:20260506.86420c0 in mdr.lock. Pin the fingerprint instead.

Use this skill whenever any NeuroClaw diffusion MRI / DWI modality skill needs to execute concrete DIPY operations: load DWI (NIfTI+bvals+bvecs), optional masking, DTI fitting, compute FA/MD/AD/RD, and extract ROI statistics. This is the dedicated base/tool skill that contains all specific DIPY code and usage patterns. Never called directly by the user.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# DIPY Tool (Base/Tool Layer)

## Overview
`dipy-tool` is the **NeuroClaw base/tool skill** that provides the concrete **DIPY** implementation for diffusion MRI (DWI/DTI) processing and feature extraction.

It is **never called directly by the user**. It is delegated to by a diffusion modality-layer skill (e.g., future `dwi-skill` / `dmri-skill`) and executed via `claw-shell` for safety, logging, and long-running stability.

This skill provides:
- Robust loading of **DWI NIfTI + bvals + bvecs** with sanity checks.
- Brain mask generation (`median_otsu`) or use of a provided mask.
- **DTI fitting** (optionally selecting a b-value range) and metric export:
  - **FA / MD / AD / RD** as NIfTI maps
- **ROI / atlas statistics** extraction (CSV summaries).

**Research use only** — not for clinical diagnosis.

## Agent Reference Rule

When the agent needs DIPY-based implementation code, it should first consult the curated snippets in `skills/dipy-tool/scripts/` instead of copying the large embedded wrapper or unrelated tutorial files with hard-coded paths.

How to install

The exact contents, by fingerprint

mdr add cuhk-aim-group/neurodiscovery/dipy-tool@sha256:5f31f6e2f44f0ffa

The line at the top of this page pins the label git:20260506.86420c0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
