The goal of CoRR was to create an open science resource for the imaging community that facilitates the assessment of test-retest reliability and reproducibility for functional and structural connectomics. In order to accomplish this, we have aggregated resting state fMRI (R-fMRI) and diffusion imaging data from laboratories around the world, and are sharing the data via the International Neuroimaging Data-sharing Initiative (INDI). http://fcon_1000.projects.nitrc.org/indi/CoRR/html/index.html
