Tool/Resource: 1000 Functional Connectomes Project

Open science initiatives are transforming the neuroimaging community. Researchers who once struggled to obtain 20-30 datasets now have unrestricted access to thousands of scans, including data obtained from developing, aging and clinical populations. Equally important, the sharing of data analysis scripts and code is becoming increasingly common, thereby enhancing the dissemination of knowledge and capabilities among laboratories – as well as facilitating replication efforts. Although exciting, we are only at the beginning. The success of open science initiatives remains dependent upon continued community participation.

Against this background, the International Neuroimaging Data-sharing Initiative (INDI) is pleased to announce the launch of its 2012 Summer of Sharing – an effort dedicated to the sustenance and acceleration of data and analytic resource sharing among imaging community members. In order to accomplish its goal the INDI Summer of Sharing initiative is requesting pledges for the contribution of:

1) DATA: Resting state fMRI and/or diffusion data employed in published studies, along with any available meta-data you’d like to share (See INDI Retro for previously shared datasets; examples include Kelly C. et al., 2011 Bio Psych, Keller C. et al., 2011 PNAS, and Power J. et al., 2012 Neuroimage).
2) ANALYTIC RESOURCES: Python, Matlab, BASH, C/C++ - we’re not choosy! INDI is actively promoting the sharing of analytic scripts and codes employed in published and/or ongoing studies through NITRC and GitHub – if you post them, we’ll help to make sure you’re recognized for it.
3) OPEN SCIENCE EVENTS: Just provide us the information and we’ll help to get the word out!
4) MISCELLANEOUS RESOURCES: Atlases, parcellation schemes, reference resources, etc. – everyone can benefit from them.

We are actively asking investigators around the world to get involved in the sharing process. Already, the following resources are scheduled for sharing this summer:
1) The Autism Brain Imaging Data Exchange (ABIDE): a global, multisite consortium of laboratories dedicated to the study of autism that will release an aggregate dataset that is expected to consist of nearly 500 individuals with autism, and their matched typically developing controls.
2) The Enhanced NKI Rockland Sample: a recently launched large-scale, R-fMRI and DTI cross-sectional, community ascertained sample of individuals between 6 and 85 years of age, accompanied by a deep phenotypic protocol that broadly samples psychiatrically relevant behavioral domains.
3) Brainhack: a Neuro-Bureau resource ( that points to collaborative projects in the field; the resource will be complemented by the Brainhack 2012 Unconference – a workshop that will blend the “unconference” and “hackathon” concepts to create a unique collaborative experience for participants interested in advancing analytic techniques and resources for functional and structural imaging.
4) The Configurable Pipeline for the Analysis of Connectomes (C-PAC): Building on the success of the release of the 1000 Functional Connectomes Project analysis scripts, the INDI team will be releasing a plug-and-play Nipype-based pipeline package that is easily configurable to accomplish a broad array of resting-state fMRI analyses.
5) DPARSF and REST: With the new releases of MATLAB-based user-friendly pipelines of Data Processing Assistant for Resting-State fMRI (DPARSF 2.2) and Resting-State fMRI Data Analysis Toolkit (REST 1.8) (, users can acquire resting-state fMRI measures efficiently (by parallel computing) and conveniently (by GUI or command line).
6) Power et al. 2011 (Neuron): The authors are now sharing the summary community assignments from their work on fcMRI networks (, and will release a suite of scripts through NITRC this summer, so that others can replicate these analyses and carry out related work. Additionally, later this summer, the dataset used for this work will be released through INDI.
7) The Child Mind Institute (CMI) Librarian Initiative: Comprehensive hand-vetted and sorted reference libraries for various literatures, including Resting State fMRI and Diffusion Tensor Imaging are now available via Mendeley, with monthly updates scheduled (

It is our hope that this list is just the beginning. We will follow with updates throughout the summer months. The success of open science depends on all of us – so get involved, and Share That Brain!
