Hi Michele
I guess after running the long you could launch a cross recon on the spatially
registered time points. You’ll have to be careful about extra interpolations
though

Subject: [Freesurfer] comparing long and cross FS aparc+aseg
External Email - Use Caution
Hi all,
I am running a test of long FS on some subjects to see if I can improve the
segmentation accuracy compared to cross FS. The aparc+aseg.mgz output of long
FS, however, is not aligned with the original timepoint structural scan, but
rather to the T1 image in the "base" folder (which I believe is an average of
the original timepoints).
I was wondering if there was a way to directly compare the results of long FS
segmentation to those of cross FS segmentation, essentially having both the
original aparc+aseg image and the new one in the same space and aligned, or if
that does not make sense since we are doing the long FS segmentation on an
effectively new image.
Thank you,
Michele
