“The Adolescent Brain Cognitive Development Brain Imaging Data Structure Community Collection (ABCC): A Community Share for the ABCD Neuroimaging Data”
Abstract: The Adolescent Brain Cognitive Development Study (ABCD), a 10 year longitudinal neuroimaging study of a population based and demographically distributed cohort of 9-10 year olds (N=11,877), was designed to overcome reproducibility limitations of prior child mental health studies. Besides numerous novel research opportunities, the extremely large size of the ABCD data set also creates novel data storage, processing, and analysis challenges for researchers. To ensure data privacy and safety, researchers are not currently able to share neuroimaging data derivatives through the central repository at the National Data Archive (NDA). However, sharing derived data amongst researchers laterally can powerfully accelerate scientific progress and ensure that the maximum public benefit is derived from the ABCD study. To simultaneously promote collaboration and data safety, we developed the ABCD-BIDS Community Collection (ABCC), which includes both curated, processed data and software utilities for further analyses. The ABCC also enables researchers to upload their own custom-processed versions of ABCD data and derivatives for sharing with the research community. This presentation highlights what’s in the ABCC, how to access the ABCC, and ABCC utilities that help researchers access, share, and analyze ABCD data, while we conclude with reproducibility analyses using ABCC utilities and data that highlight the need for larger sample sizes.
The presentation is based on a paper available on biorxiv.
All are welcome.
