Dear FreeSurfers,
Due to motion I have to exclude participants from my analysis.
Is there an objective measure which could serve as a cut off value concerning motion in the scanner? Can I find it in one of the FreeSurfer files generated through the recon-all process?
Subjectively, one can see which images are good or good enough for segmentation. But I'd rather like to include or exclude participants based on an objective threshold.
Thank you very much in advance, Best regards, Ines
