dipy-tool skillA

dipy-tool is agent-read markdown (skill) from cuhk-aim-group/neurodiscovery: 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..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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

Latest version
mdr add cuhk-aim-group/neurodiscovery/dipy-tool@git:20260506.86420c0
Exact content
mdr add cuhk-aim-group/neurodiscovery/dipy-tool@sha256:5f31f6e2f44f0ffa

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
