What problem does it solve? Working with the NACC SCAN Alzheimer's imaging cohort requires navigating access approvals, DICOM/NIfTI staging, BIDS organization, phenotype linkage, and modality-specific processing while respecting strict privacy and data-use rules. This Skill orchestrates that entire pipeline so an approved local export becomes an auditable, analysis-ready dataset. ## Core Features & Use Cases - Access-Gated Intake: Enforces the NACC Quick Access approval workflow and builds a checksummed manifest of the approved export before any processing begins. - BIDS Staging and Modality Delegation: Converts DICOM via dcm2nii, organizes data with bids-organizer, and delegates MRI, fMRI, DWI, ASL, and PET processing to dedicated modality skills. - Phenotype Linkage with Privacy Controls: Joins NACC clinical/UDS tables to imaging records using documented keys, keeps identifiers in a restricted crosswalk, and reports unmatched or duplicated records. - Use Case: A researcher receives an approved SCAN export containing DICOM MRI and amyloid PET scans plus NACC clinical tables, and uses this Skill to produce a validated BIDS dataset, SUVR derivatives, QC reports, and a keyed phenotype analysis table. ## Quick Start Use the scan-skill to inventory, convert, and BIDS-organize my approved SCAN export located in the local export folder, then process the available MRI and PET modalities.
