# ADHD-200 Skill (Dataset-Orchestration Layer)
## Overview
`adhd200-skill` is the NeuroClaw orchestration skill for the **ADHD-200** dataset.
It coordinates a fixed three-phase workflow:
1. Download ADHD-200 data from the FCP/INDI repository.
2. Prepare and validate BIDS-style data organization for downstream processing.
3. Delegate modality pipelines to `smri-skill` and `fmri-skill`.
It also provides **phenotype extraction** and **QC integration** paths:
- Extract and merge ADHD-200 phenotype tables (diagnosis, ADHD measures, demographics, medication).
- Generate per-subject QC summaries with exclusion lists.
This skill follows NeuroClaw hierarchy:
- Defines **WHAT to do**, not low-level implementation details.
- Does **not** execute direct shell commands itself.
- Delegates all execution via `claw-shell` to base/tool skills.
**Research use only.**

## Download Stage (Mandatory First Step)
### Source
ADHD-200 data is distributed through the **FCP/INDI** repository:
- Website: https://fcon_1000.projects.nitrc.org/indi/adhd200/
### Supported ADHD-200 Data Packages
- **Imaging data**: T1w, rs-fMRI (NIfTI format) from 8 imaging sites
- **Phenotype data**: CSV files with diagnosis, ADHD measures, demographics, medication history, QC measures
- **Sites**: Peking, Brown, NYU, KKI, NeuroImage, OHSU, Pitt, Washington University
### Delegation Rules for Download
- Environment/setup checks: `dependency-planner` + `conda-env-manager`
- Download tool installation and execution: `claw-shell`
- Optional raw-data organization to BIDS-style staging: `bids-organizer`
### Download Inputs to Confirm in Plan
- Target subset (full cohort, specific sites, or ADHD/control only)
- Subject list scope (full or custom IDs)
- Destination directory with sufficient disk space
---
## Narrow Path: ADHD-200 Raw NIfTI -> BIDS Staging
Use this path when the task only asks to reorganize raw ADHD-200 NIfTI files into a BIDS-style dataset and does not require preprocessing, ROI extraction, phenotype merging, or downstream analysis.
### When this narrow path should dominate
- The task objective is limited to ADHD-200 NIfTI staging, BIDS renaming, sidecar handling, and dataset-level metadata.
- Inputs are already local ADHD-200 NIfTI files or ADHD-200-style subject/site folders.
- The required deliverable is a direct staging script or command sequence, not a plan for fMRIPrep or downstream analysis.
### Narrow-path contract
- Do not widen the solution to fMRIPrep, ROI extraction, phenotype merging, or downstream analysis unless the task explicitly requires them.
- Treat this as a direct file-organization problem: scan ADHD-200 subject/site layout, normalize subject labels, map modalities to BIDS names, copy or symlink NIfTI plus matching sidecars, and write dataset-level metadata plus staging logs.
- If the task is benchmark-style, prefer a single direct end-to-end staging script over a confirmation-first orchestration plan.
### Expected narrow-path behavior
1. Detect ADHD-200-style subject IDs (numeric, e.g., `0010002`) and normalize to BIDS labels such as `sub-0010002`.
2. Detect site information and encode in `participants.tsv`.
3. Route modalities:
- T1w -> `anat/*_T1w`
- rs-fMRI/BOLD -> `func/*_task-rest_bold`
4. Preserve or rename matching JSON sidecars when available.
5. Emit dataset-level outputs such as `dataset_description.json`, `participants.tsv`, `README`, and a manifest or skipped-file report.
---
## Core Workflow (Never Bypassed)
1. Identify user target: full ADHD-200 download, imaging subset, phenotype extraction, or BIDS staging only.
2. Generate a numbered plan with tools, outputs, runtime, storage, and risks.
3. Wait for explicit confirmation (`YES` / `execute` / `proceed`).
4. On confirmation, run download stage first (if needed).
5. After download success, run BIDS preparation using `scripts/reorganize_adhd200.py`.
6. Delegate to modality skills:
- `smri-skill` for structural MRI (T1w)
- `fmri-skill` for resting-state fMRI (rs-fMRI)
7. If phenotype extraction is requested, run `scripts/extract_adhd200_phenotype.py`.
8. If QC summary is requested, run `scripts/adhd200_qc_summary.py`.
9. Save outputs into an ADHD-200-centered structure under `adhd200_output/`.

## Input Layout (Example)
Subject `0010002` from site Peking:
```
adhd200_raw/
Peking/
0010002/
anat/
anat.nii.gz
func/
rest.nii.gz
phenotype/
ADHD200_..._phenotypic.csv
```
---
## BIDS Preparation
### Script: `scripts/reorganize_adhd200.py`
Converts ADHD-200 raw directory structure to BIDS-compliant layout.
```bash
python skills/adhd200-skill/scripts/reorganize_adhd200.py \
--input /path/to/adhd200_raw \
--output /path/to/adhd200_bids \
--phenotype /path/to/adhd200_raw/phenotype/ADHD200_phenotypic.csv
```
Features:
- Subject ID normalization: numeric ADHD-200 IDs to BIDS `sub-NNNNNNN`
- Site extraction and encoding in `participants.tsv`
- Modality routing: T1w, rs-fMRI
- `dataset_description.json` and `participants.tsv` generation with phenotype metadata
- Dry-run mode: `--dry-run` to preview without copying

## Multimodal Processing Delegation
| Modality | Delegated skill | Typical tasks | Main outputs |
|---|---|---|---|
| sMRI (T1w) | `smri-skill` | brain extraction, tissue segmentation, cortical reconstruction | `smri_output/` |
| rs-fMRI | `fmri-skill` | preprocessing, denoising, ROI time series, connectivity | `fmri_output/` |
---
## Phenotype Extraction
### Script: `scripts/extract_adhd200_phenotype.py`
```bash
python skills/adhd200-skill/scripts/extract_adhd200_phenotype.py \
--phenotype-dir /path/to/adhd200_raw/phenotype \
--output /path/to/adhd200_output/phenotype/merged_phenotype.csv \
--columns subject,DX,AGE,SEX,ADHD_Index,Inatt,HyperImp \
--imaging-ids /path/to/adhd200_output/bids/participants.tsv
```
---
## QC Integration
### Script: `scripts/adhd200_qc_summary.py`

python skills/adhd200-skill/scripts/adhd200_qc_summary.py \
--fmriprep-dir /path/to/adhd200_output/fmriprep \
--freesurfer-dir /path/to/adhd200_output/smri/freesurfer \
--output /path/to/adhd200_output/qc/qc_summary.csv \
--exclude-output /path/to/adhd200_output/qc/exclude_list.csv \
--fd-threshold 0.3
```

## Recommended Output Layout
All assets should be organized under `./adhd200_output/`:
- `adhd200_output/raw/` (downloaded original files)
- `adhd200_output/bids/` (staged BIDS data)
- `adhd200_output/smri/` (links or copies from `smri_output/`)
- `adhd200_output/fmri/` (links or copies from `fmri_output/`)
- `adhd200_output/phenotype/` (merged phenotype tables)
- `adhd200_output/qc/` (QC summaries and exclusion lists)
- `adhd200_output/logs/` (download + orchestration logs)
---
## Benchmark Adapter Guidance
For benchmark-style prompts, do not force the full `download -> staging -> multimodal processing` orchestration when the task is only asking for local ADHD-200 data staging or organization.
- If the task starts from raw ADHD-200 data already present on disk and only asks for BIDS-style staging / organization:
- skip the mandatory download stage
- default to the narrow path `local raw ADHD-200 discovery -> BIDS-style staging -> minimal metadata -> validation/report`
- In benchmark mode, do not require explicit confirmation before presenting the direct staging solution.
---
## Safety and Execution Policy
- No execution before explicit plan confirmation.
- All execution must be routed via `claw-shell`.
- Missing dependencies must be resolved by `dependency-planner` before running.
---
## Important Notes and Limitations
- ADHD-200 has heterogeneous acquisition parameters across 8 sites; site effects must be addressed in analysis.
- ADHD-200 subject IDs are numeric and vary in length across sites.
- Diagnosis labels vary by site (ADHD-combined, ADHD-inattentive, ADHD-hyperactive, typically developing).
- ADHD-200 data does not include task-fMRI; only resting-state fMRI is available.
- `adhd200-skill` is orchestration-only; detailed preprocessing logic remains in `smri-skill` and `fmri-skill`.
---
