Hi Kayti
that's pretty hard to say. Even a few ms of TE for example can make a pretty big differeence in e.g. avoiding dura. In general of course we try to fix the acquisition parameters and at the very least balance your populations across different scan types. Can you give us more details or an example? Bruce

Hello,
I’m curious if anyone has any insights about comparing T1s from different subjects that have different acquisition parameters in Freesurfer. I’m trying to get a feel for how different is too different in regards to comparing differently acquired T1s with Freesurfer. Are there any parameters that must stay consistent in order for Freesurfer to generate comparable outputs between subjects? Any other thoughts?
Thank you!
