What problem does it solve? Working with the IXI (Information eXtraction from Images) dataset requires coordinating multiple steps: downloading ~600 subjects from three London hospital sites, converting the native directory layout to BIDS, and processing T1w, T2w, and MRA modalities. This Skill orchestrates that entire pipeline by delegating each stage to the appropriate tool skill, so you get a reproducible end-to-end workflow instead of ad-hoc scripts. ## Core Features & Use Cases - BIDS Staging: Converts IXI native layout (e.g., IXI002-T1.nii.gz) into BIDS-compliant structure with dataset_description.json, participants.tsv, and site-specific scanner metadata via scripts/reorganize_ixi.py. - Multi-Site Awareness: Automatically detects acquisition site (Hammersmith 3T Philips, Guy's 1.5T Philips, IOP 1.5T GE) from subject ID prefixes and records scanner details for site-effect analysis. - Modality Delegation: Routes T1w/T2w structural processing to smri-skill and MRA vessel analysis to nibabel-skill, with per-subject QC summaries via scripts/ixi_qc_summary.py. - Use Case: You need to run a multi-site structural MRI study on IXI. The Skill generates a numbered execution plan, waits for your confirmation, then stages the data to BIDS, runs brain extraction and tissue segmentation, and produces QC summaries with exclusion lists in a clean ixi_output/ directory. ## Quick Start Ask the agent to download the IXI dataset, stage it to BIDS, and run structural MRI processing on the T1w images with a QC summary.
