Hi Markus

can you send us an example of where you think the volume is far too low? Tar and gzip the entire subject dir and put it on our filedrop

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
