The HCP consortium is pleased to announce the release of fully reprocessed 7T fMRI data for 184 HCP-Young Adult (HCP-YA) subjects for download on ConnectomeDB. The rerelease corrects the error in the 7T preprocessed fMRI data for all subjects and includes other updates, plus the addition of multirun ICA FIX-cleaned 7T retinotopy data.
Why was the reprocessing necessary?
In the previously released 7T preprocessed fMRI data (available March-July, 2017), all 7T fMRI scans with anterior-to-posterior, A->P phase-encoding (labeled *_AP) were unwarped using the incorrect direction in the fMRIVolume pipeline, causing the voxels in these scans to be spatially misplaced. Since the issue occurred in the early stages of preprocessing, we have fully reprocessed all the 7T fMRI data which is now available for download on ConnectomeDB.
This release includes:
In addition, the HCP S1200 Reference Manual has been fully updated with new information regarding 7T data collection and protocol details and other fixes since the S1200 release.
A manuscript (Benson et al. 2018) presenting results of an analysis of the HCP retinotopy data is soon to be released, along with retinotopy analysis data and Connectome Workbench scenes to be released on the Open Science Framework and in the BALSA database. When these resources are available, we will announce the release on the HCP-Users email forum (sign up here).
Along with the release, we also fixed a bug in the Amazon Web Services (AWS) access key regeneration function on ConnectomeDB. Let us know if you have any issues regenerating your keys.
Other changes are happening behind-the-scenes at the AWS Public Data Sets program. These changes should not affect users of the HCP data on AWS, but they are delaying our upload of the reprocessed 7T data to our AWS S3 bucket (currently only 3T and Retest HCP data are available on S3). Stay tuned for an announcement when 7T data is available.
In case you missed it.... as of March 2, 2018, all SNP Genotypes collected for HCP-Young Adult (HCP-YA) subjects have been released on dbGaP.
