Hi Jennifer, Many thanks for this! I'm not sure how I missed it... I do have one additional question: Why is the 100-unrelated group average only available for the task fMRI data? Won't any effects of relatedness be equally relevant for resting-state and structural data, or has family structure already been taken into account in the analyses of the R468 connectivity and R440 structural datasets?

If you have questions beyond what is there, repost to the list and we can answer them more specifically.

The release notes file included in the download (ReleaseNotes_HCP_Q1-Q6_GroupAvg_Related440_Unrelated100_v1.txt) points to the data reference manual and two papers describing data acquisition etc, but I cannot seem to find any detailed information on specifically these group average datasets. I'm particularly interested in how the averaging was done for the 440-subject task activation maps, and the 468 group-PCA eigenmaps. Many thanks in advance!
