[Freesurfer] Using Freesurfer for skull stripping then reorienting images to use in FSL

Hello,

We are using freesurfer to skull strip T1 images on a high-motion pediatric sample. We want to use freesurfer to get brain-only images and then do further analysis using FSL. The problem is that, in freesurfer, the images are in a different orientation than those in FSL. For example, the same brain extracted image in freesurfer seems to be rotated a bit more to the left than the image extracted in FSL.

QUESTION: Does anyone with freesurfer or FSL knowledge know how to convert the freesurfer’s brain-only images so that we can use them in FSL for ICA (both group and individual) as well as TBSS and Tractography ( back on freesurfer)?

Thank you for your time and expertise.

Cheers, Sara
