ABIDE I and II

Autism Brain Imaging Data Exchange (ABIDE)

Description:

ABIDE is a collaboration of 16 international imaging sites that have aggregated and are openly sharing neuroimaging data from 539 individuals suffering from ASD and 573 typical controls. These 1112 datasets are composed of structural and resting state functional MRI data along with an extensive array of phenotypic information.

ABIDE II established to further promote discovery science on the brain connectome in ASD. To date, ABIDE II has aggregated over 1000 additional datasets with greater phenotypic characterization, particularly in regard to measures of core ASD and associated symptoms. In addition, two collections include longitudinal samples of data collected from 38 individuals at two time points (1-4 year interval). To date, ABIDE II involves 19 sites - ten charter institutions and seven new members - overall donating 1114 datasets from 521 individuals with ASD and 593 controls (age range: 5-64 years).
