To investigators that have used the instructions in HCP FAQ #9, "How do I map data between FreeSurfer and HCP?" ( https://wiki.humanconnectome.org/display/PublicData/HCP+Users+FAQ):
A new atlas-to-atlas registration has been computed, which improves upon the original version of these instructions. Compared to the original registration used, the new registration has shifts of a few millimeters in many parts of the cortex. It was computed in a method similar to "dedrifting", making use of the freesurfer registrations that are a byproduct of the processing pipelines. As part of this change, the latest pipelines release (v3.22.0) contains the updated resampling files in the resample_fsaverage folder. However, part of the resampling instructions have also changed, specifically part D, "resampling individual data from fs_LR to fsaverage" Appendix 3 of the new instruction document contains details of the change in the registration, and steps you can take to use the new registration, even if you no longer have the data prior to resampling. This appendix also says where to find the old files from the previous resampling instructions, if you need to continue using the old registration. The new instructions, including this appendix, are here: https://wiki.humanconnectome.org/download/attachments/63078513/Resampling-FreeSurfer-HCP_5_8.pdf Tim Coalson, David Van Essen, Matt Glasser _______________________________________________ HCP-Users mailing list [email protected] http://lists.humanconnectome.org/mailman/listinfo/hcp-users
