Dear Freesurfer Community!
Recently I started working with Freesurfer and had a number of
subjects processed through the pipeline (recon-all -autorecon-all
-subjid subjname) without error.
So far I am mainly interested in the outcome of the segmentation
of subcortical regions found in ../stats/aseg.stats. However, of
about 20% of the scans the calculated volumes were far
below the normal range. I couldnt figure out why it sometimes
doesnt work properly. All scans came from the same scanner, protocol, had
same orientation, etc. Perhaps I need some "finetuning"? How can I manage to
make the segmentation work correctly though? thanx in advance!
Markus
