[Freesurfer] FSFAST with reoriented reconstruction

Hi Freesurfer users.

I performed the recomended reconstruction of 82 subjects with Freesurfer.

The images used for this reconstruction were previously reoriented to AC-PC position, because they were previously used for SPM purposes.

Now I'm trying to perform the FSFAST workflow, and I had to unpack the original functional DICOMs for each subject. Those images are not reoriented because they were not used until now.

The question is: The functional images should be previously reoriented to the same position as the anatomical used in Freesurfer?

Should I perform the recomended reconstruction again with the original DICOMS?

Or it doesn't matter the reorientation of the functional/anatomical images and Freesurfer would perform correctly the FSFAST? (I hope so, so I could skip the reconstruction, which involves many hours of processing)

Thanks.
