This repository contains code for maintenance of a dataset containing research quality T1 MRI images (e.g., resolution of 1mm isotropic or below) of healthy controls (no history of neurological disorder) scanned at the University of Pennsylvania (N=868).
The impetus of this project was to create a cortical thickness template including subjects across the entire age spectrum for calculating "neuroprint" heatmaps that illustrate an individual's age-adjusted atrophy. The repository for that initiative can be found here.
The data were gathered into a Flywheel Collection and visually inspected for motion and other artifacts.
