Human Connectome Project (HCP) Releases First Quarter of Data
March 5, 2013 The Human Connectome Project (HCP) WU-Minn consortium is pleased to announce the HCP Q1 Release, our first quarterly release of HCP image and behavioral data. Should I be interested in the HCP Q1 data release? The HCP aims to study 400 subjects per year, with a target of 1,200 subjects studied before the grant ends in 2015. Subjects from families with twins and non-twin siblings are being scanned on the same scanner using the same protocol for every subject. Data will be released quarterly, starting with the current Q1 release. The Q1 data release is limited in terms of the number of subjects extensively scanned (68 vs the eventual target of 1,200 subjects), the amount of highly processed data that is available, and the data mining capabilities currently implemented. Consequently, we anticipate that the Q1 data release will be of particular interest to investigators who are prepared to apply their own neuroimaging analysis tools to this 'starter kit' of imaging data - especially by using the 'minimally preprocessed' datasets described below. Investigators interested in extensively processed data can access a 20-subject group-average dataset that includes multiple modalities. What's in the HCP Q1 data release? The Q1 data include high-resolution MR scans from 68 healthy adults and four imaging modalities: structural images (T1w and T2w), resting-state fMRI (rfMRI), task-fMRI (tfMRI), and high angular resolution diffusion imaging (dMRI). Some of the behavioral data acquired from each subject is also available. Family status and other potentially sensitive information are part of the Restricted Access data is available only to qualified investigators (see below). To enable investigators to analyze data without being concerned about family structure issues, we have prepackaged groups of 5 and of 20 unrelated subjects for download. Multiple levels of data processing. The Q1 imaging data includes "unprocessed" data (in NIFTI format) plus "minimally preprocessed" datasets. We encourage investigators to use the preprocessed datasets, in which spatial distortions have been minimized and data have been aligned across modalities and across subjects. The methods used for this preprocessing were implemented by the HCP consortium through an intensive two-year refinement and optimization process. If your specific research interests make it important to use the unprocessed data, it is critical to be aware of that the HCP unprocessed images for ALL modalities contain unusually large gradient and it is important to correct for the spatial distortions they cause (see details in the HCP Q1 Data Release Reference Manual <http://humanconnectome.org/documentation/Q1/> ). The preprocessed structural datasets include cortical surfaces, myelin maps, and other data that are suitable for a variety of morphometric analyses. In addition, the HCP has analyzed resting-state fMRI and task-fMRI data on the group of 20 unrelated Q1 subjects. The Q1 data release includes demonstration datasets based on group-average functional connectivity and task-fMRI. The extensively processed data for the individual subjects used in this analysis are not being released at this time because key methods are still being evaluated and refined (e.g., temporal preprocessing, denoising, and correcting for residual motion artifacts). Access Q1 data on the HCP website. Explore, download, or order the entire HCP Q1 dataset <http://humanconnectome.org/data/> (~2TB of data!) via the ConnectomeDB database. Most HCP image and behavioral data is open access to investigators worldwide who register and accept a limited set of Open Access Data Use Terms <http://humanconnectome.org/documentation/data-release/DataUseTerms-HCP-Open -Access-15Feb2013.pdf> . Sensitive behavioral, demographic, and family structure data is available to qualified researchers who apply for Restricted Data Access <http://humanconnectome.org/documentation/connectomeDB/access/restricted-acc ess-data.html> . Want more information? The HCP Q1 Data Release Reference Manual <http://humanconnectome.org/documentation/Q1/> provides comprehensive information that includes details on imaging protocols, behavioral measures, and information that will help users obtain and analyze the Q1 data.
