Hi Freesurfer developers,
I am processing several thousand MRIs through Freesurfer and have come across >200 cases where recon-all failed due to the automated talairach QA check. In these cases, I do see some which have bad transformations and others which look acceptable to me. After freesurfer runs, we review the cortical ribbon from the aparc+aseg file to the quality of the parcellation.
My question: what problems might arise from using the "-notal-check" on all our freesurfer runs which would not be caught by looking at the parcellation?
I am also wondering if you have the "RLB700_preprocessing_statistics.pdf" document which the code references
# now run Avi's QA check on the results found in talairach_avi.log # see document RLB700_preprocessing_statistics.pdf for details
Thanks for your time, Tyler
