What problem does it solve? Processing the OASIS (Open Access Series of Imaging Studies) dataset for aging and Alzheimer's disease research requires coordinating BIDS validation, structural MRI preprocessing, and clinical phenotype extraction across multiple tools, which is error-prone when done manually. ## Core Features & Use Cases - BIDS Validation: Validates OASIS-1, OASIS-2, and OASIS-3 directory structures, detects dataset version, and reports modality completeness per subject. - Phenotype Extraction: Merges CDR, MMSE, demographic, and clinical data from multiple files into a single subject-aligned CSV table. - QC Summaries: Generates per-subject quality control reports with framewise displacement thresholds and exclusion lists, annotated with CDR/MMSE group info. - Use Case: A researcher downloads OASIS-3 data and needs to validate its BIDS structure, run cortical thickness analysis via sMRI processing, and merge CDR scores with imaging subject IDs before statistical analysis. ## Quick Start Ask the agent to validate the BIDS structure of your local OASIS dataset and extract the phenotype table with CDR and MMSE scores into a merged CSV.
