Retest HCP Issue A Subjects:


Issue code B: Segmentation and Surface QC

All brain surfaces and brain structure segmentation results generated by FreeSurfer as part of the HCP structural pipeline were also inspected by a rater for any notable issues see Appendix 4: Post Session 1 Quality Control SOP, pp. 25-28). If there were major segmentation or surface errors, we reran the pipeline to attempt to fix the issues in an automated way (due to the cohort size of the HCP and limited staff resources, hand editing of segmentations and surfaces was not attempted on any subjects).
