HCP Young Adult

HCP-Young Adult 2025 Release

Release Date: Aug 11, 2025
Type: Data Release

The HCP-Young Adult 2025 Release is available on a new platform, "ConnectomeDB powered by BALSA". 

HCP-YA 2025 Highlights:

  • Updated processing on previously released 3T, 7T, and Retest subjects to include:

    • Spin-echo based ("SEBASED") intensity bias field correction of all the fMRI data, 

    • Elimination of the regression of movement regressors as a step in the fMRI data cleaning (see Glasser et al., 2019 Neuroimage), 

    • Addition of multi-run FIX for the 3T task fMRI data, and 

    • Addition of Reclean (improvements to spatial ICA) and Temporal ICA pipelines and processed output for all 3T and 7T fMRI data. 

    • Due to these updates, data from this 2025 Release should not be mixed with the previous "S1200" Release (from 2017).

  • Data are processed and repackaged to match packages released for the HCP Lifespan projects. The new packages are significantly different than the ones currently available on ConnectomeDB that will be retired soon.

  • Processed data are available for 1071 subjects (45 retest subjects) without processing errors and with at least one rfMRI run to enable MSMAll registration. Unprocessed data are available for all subjects with imaging data (1113 subjects).

  • Directory structure of unzipped data is unchanged.

  • Non-imaging data are unchanged. Restricted data are available to those approved for access.

Nearly all of the documentation of the S1200 Release still applies. We have produced a new Appendix 3 updated with the new data files and reorganized for the new packages.
