fsl-tool SKILL.md skillA

fsl-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/fsl-tool@git:20261014.f405841

Pins git:20261014.f405841 in mdr.lock. Pin the fingerprint instead.

Plan or run FSL structural, functional and diffusion MRI commands. Choose the requested analysis stage from the available inputs, including tracking from existing bedpostx results.

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

# FSL Tool

Use FSL for the requested analysis stage. Existing processed inputs do not
imply that preprocessing should be repeated. Keep the user's output location.
Loading this document provides method guidance; it does not install FSL,
execute commands, launch a delegate, or verify images.

## Select the stage

| Supplied input / requested result | Relevant command |
|---|---|
| T1w / structural preprocessing | `fsl_anat` |
| Brain extraction only | `bet` |
| Tissue segmentation of extracted anatomy | `fast` |
| fMRI motion correction | `mcflirt` |
| Task GLM with an actual design file | `feat design.fsf` |
| Resting-state ICA | `melodic` |
| Raw diffusion with acquisition metadata | `topup` / `eddy` as applicable |
| Corrected diffusion / tensor maps | `dtifit` |
| Corrected diffusion / crossing-fibre model | `bedpostx` |
| Existing bedpostx samples / probabilistic tracking | `probtrackx2` |
| Requested atlas-protocol tract extraction with registration | `xtract` |

Parameters such as BET fraction, ICA dimension and streamline count are
analysis choices, not defaults that apply to every dataset. Check the installed

How to install

The exact contents, by fingerprint

mdr add cuhk-aim-group/neurodiscovery/fsl-tool@sha256:ea006bb36cb3d673

The line at the top of this page pins the label git:20261014.f405841, 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.
