Dear freesurfer gurus, I noticed something unusual in some of our data today. When the command mri_info was run on some of the orig.mgz volumes the values listed for echo time and flip angle in some of the scans were 0.00, even though there was a listing for repetition time. What could have caused this? Could misinformation in the header cause variation in the freesurfer processing of that scan? Cheers, Jared
