I have ran a subject through fmri-prep and have inspected the output files. This subject appears to have an abnormally large sulci. We are waiting on the neuroradiologist’s feedback.
In the meantime, has anyone encountered such a case where the T1w image appears as such (see image: participant at the x=0 coordinate) and the spatial normalization drastically corrects the image to align with the template as such (see image: MNI space)?
Is this a case that would be too extreme in terms of spatial normalization and need to be discarded?
