Hi Freesurfer Experts,
We are on the process of troubleshooting on all of our subjects and come across with the problem that we have not faced before. Here it is:
We have several subjects that their heads were not in a perfectly straight line captured by using MRI. Does that affect to the segmentation of a recon, and more importantly somehow carry out some statistical values for further analysis (volume, cortical thickness)?
As you can see, Axial view shows the head being tilted to the right. Sagital_lh and Sagital_rh images show how the white matter and gray matter segmentation are being bounded on the same slice 130 but in different hemisphere.
Do we need to do something about it? If yes, how are we going to fix it?
We are greatly appreciated to your patience and hopefully to get your response as soon as possible.

I think it should be fine. Do the segmentations and surfaces look accurate?

They are fine. Thank you.
