Abstract

The Adolescent Brain Cognitive Development Study (ABCD), a 10 year longitudinal neuroimaging study of the largest 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 the fantastic wealth of research opportunities, the extremely large size of the ABCD data set also creates enormous 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, to ensure 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 NeuroResource is meant to serve as the companion guide for the ABCC. In section we describe the ABCC. Section II highlights ABCC utilities that help researchers access, share, and analyze ABCD data, while section III provides two exemplar reproducibility analyses using ABCC utilities. We hope that adoption of the ABCCs data-safe, open-science framework will boost access and reproducibility, thus facilitating progress in child and adolescent mental health research.

A curated collection of processed ABCD neuroimaging derivatives plus utilities for access, sharing and analysis, letting researchers exchange derivatives they cannot share through the central archive.

ABCD imaging data are large enough that storage, processing and analysis are a barrier on their own, and privacy and safety rules stop researchers sharing neuroimaging derivatives through the central National Data Archive, even though lateral sharing of derived data could accelerate progress. The ABCD-BIDS Community Collection offers curated processed data, utilities and a route for researchers to post their own processed versions, framed by the authors as a data-safe way to share derivatives laterally.

Key results

  1. ClaimedThe ABCD-BIDS Community Collection packages curated processed imaging data together with software utilities for access, sharing and analysis, and accepts custom-processed versions contributed by other researchers.

    Described in the abstract as the design and purpose of the resource, motivated by the central repository's inability to redistribute derivatives. No counts of participants, derivatives, pipelines or utilities are given, and no usage or performance figures appear. · Abstract

  2. ClaimedThe manuscript is structured as a companion guide: a description of the collection, a walkthrough of its utilities, and two worked reproducibility analyses built on them.

    The abstract names the three sections but reports no outcome, metric or dataset for the two exemplar reproducibility analyses, so nothing about their results can be assessed from this text. · Abstract

Methods, data and reproducibility

A curated collection of processed Adolescent Brain Cognitive Development (ABCD) neuroimaging derivatives released alongside software utilities for access, sharing and analysis, plus a route for researchers to contribute their own processed versions. The abstract does not describe the processing pipelines, file formats or access controls.

  • Adolescent Brain Cognitive Development (ABCD) study: 10-year longitudinal neuroimaging of a population-based, demographically distributed cohort recruited at ages 9-10 · human · n = N=11,877
Methods & tools
ABCD-BIDS Community Collection (ABCC), National Data Archive (NDA)
Reproducibility gaps
Abstract only: no repository, download location or access procedure appears in the text, and the National Data Archive is described as unable to redistribute neuroimaging derivatives.
Limitations (3)
  • Neuroimaging derivatives cannot be shared through the central National Data Archive repository, the restriction this collection is built to work around. · stated by the authors
  • Abstract only, so the collection's contents, processing pipelines, access terms and the outcome of the two reproducibility analyses cannot be judged from this text. · noted in this summary
  • Part of the value depends on researchers uploading their own processed versions, and no quality or provenance controls for those contributions are described here. · noted in this summary

Read this if you work with ABCD neuroimaging data and would rather start from a shared collection of processed derivatives and utilities than reprocess the cohort yourself.
