SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pandas, and includes scripts (resource) components.

What problem does it solve? Processing the HCP Development (HCP-D) dataset requires coordinating ConnectomeDB downloads, BIDS reorganization, and separate sMRI, fMRI, and dMRI pipelines, which is error-prone when done manually across hundreds of pediatric subjects. ## Core Features & Use Cases - End-to-End Orchestration: Plans and delegates the full HCP-D workflow from ConnectomeDB download through BIDS staging to modality-specific processing via dedicated skills. - BIDS Reorganization: Converts HCP-D native directory layouts into BIDS-compliant datasets with task mapping, sidecar metadata, and dataset_description.json generation. - Phenotype Extraction and QC: Merges developmental, cognitive, and behavioral phenotype tables and generates per-subject QC summaries with pediatric-adjusted motion thresholds. - Use Case: A researcher downloads 200 HCP-D subjects, stages them into BIDS format, runs structural and functional MRI preprocessing, and produces a merged phenotype CSV plus an exclusion list of high-motion subjects. ## Quick Start Ask the agent to download the HCP Development dataset from ConnectomeDB, convert it to BIDS format, and run the full sMRI, fMRI, and dMRI processing pipeline.

FAQPage Schema
How do I process the HCP Development dataset end to end?

Use this skill to generate a numbered execution plan covering ConnectomeDB download, BIDS staging, and sMRI/fMRI/dMRI processing. After you confirm the plan, each step is delegated to the appropriate modality skill and outputs are saved under hcpd_output/.

How to convert HCP-D native data to BIDS format?

Run the reorganize_hcpd.py script with --input pointing to raw HCP-D data and --output for the BIDS target. It normalizes subject IDs, maps task fMRI runs to BIDS labels, and generates dataset_description.json, with a --dry-run mode for previewing.

What modalities does HCP Development data include?

HCP-D includes T1w and T2w structural MRI, diffusion MRI, resting-state fMRI, and seven task fMRI paradigms such as MOTOR, EMOTION, GAMBLING, and working memory. The cohort covers roughly 600 participants aged 5 to 21 years.

Does HCP-D processing require special QC thresholds for children?

Yes, pediatric populations show higher head motion, so the QC script uses a default framewise displacement threshold of 0.4 mm rather than stricter adult values. Age-appropriate templates and atlases may also be needed for structural processing.

Can I skip the download stage if HCP-D data is already local?

Yes, when raw HCP-D data already exists on disk, the skill supports a narrow path of local discovery, BIDS staging, minimal metadata generation, and validation without the mandatory download step.
