# parcellate

`parcellate` is a BIDS App for extracting regional statistics from scalar neuroimaging maps using atlas-based parcellation. It integrates with **CAT12** (VBM) and **QSIRecon** (dMRI) preprocessing pipelines and produces tidy TSV tables suitable for downstream analysis and quality control.
