title: Data Sharing of the Phase II from the DIRECT Consortium

description: Background and RationaleMajor depressive disorder (MDD) is among the top global contributors to disability and disease burden. Despite rapid advances in brain imaging, the translation of neuroimaging biomarkers into clinical psychiatry has been limited—primarily due to inconsistent findings, small sample sizes, and analytic heterogeneity. To address these critical barriers, the Depression Imaging REsearch ConsorTium (DIRECT) was launched in 2017, aiming to build large-scale, harmonized datasets for the scientific community.The first phase of DIRECT—the REST-meta-MDD Project—aggregated resting-state fMRI data from 1,300 MDD patients and 1,128 healthy controls across 25 cohorts, using a standardized preprocessing pipeline (DPARSF). These data were openly shared (https://rfmri.org/REST-meta-MDD) and have already enabled influential discoveries (see Yan et al., PNAS 2019; Chen et al., Psychoradiology 2022). However, REST-meta-MDD Phase I was limited to region-of-interest (ROI) level indices.What’s New in DIRECT Phase IIBuilding on the success and collaborative infrastructure of REST-meta-MDD, DIRECT Phase II has now assembled and harmonized a dramatically expanded dataset—comprising voxel- and vertex-level BOLD time series and T1-weighted structural MRI from 1,660 MDD patients and 1,341 healthy controls across 23 cohorts. All participating sites used the advanced DPABISurf pipeline (see Yan et al., Science Bulletin 2021), and all researchers completed dedicated training to ensure maximal harmonization and quality control.This resource represents the largest, most detailed open neuroimaging dataset for MDD to date, providing unprecedented opportunities for reproducible, high-powered investigation of functional connectivity (FC) alterations in depression, biomarker discovery, and translational research—from basic mechanisms to individualized intervention strategies (Chen et al., Science Bulletin 2025).Key FeaturesScale: 1,660 MDD patients + 1,341 healthy controls; 23 cohorts; harmonized protocolData: Voxel/vertex-level resting-state fMRI time series, T1 structural images, standardized phenotypic dataPipeline: Unified preprocessing (DPABISurf); all sites trained for consistent data handlingCommunity Impact: Enables cross-site reproducibility, large-scale data-driven biomarker discovery, and benchmarking of new analytic methodsDetailed information about each site and imaging parameters can be found in the Supplementary Information of Chen et al. (2025, Science Bulletin).Data Sharing Process and RequirementsFollowing the successful data-sharing model established in REST-meta-MDD, DIRECT Phase II data will be shared in two phases:1.Coordinated Sharing (from publication until Jan 1, 2026):Interested researchers submit a brief letter of intent to rfmrilab@gmail.com.Proposals are reviewed for potential overlap. Approved proposals are notified of ongoing projects, helping researchers avoid duplication and fostering collaboration.We welcome new, innovative proposals—especially those that expand the field or apply novel analytic methods.2.Unrestricted Sharing (from Jan 1, 2026):Full open access to all qualified researchers.Analyses and applications are welcomed, provided that standard citation guidelines and ethical requirements are followed.Citation and Acknowledgement RequirementsAll users must cite the Data Announcing Science Bulletin paper describing the DIRECT Phase II dataset:Chen X, Lu B, Wang Y-W, et al.
