Yes, all we did in this case was change amygdala to hippocampus and in other cases white matter to hippocampus or vice versa.

can you cc the list? So all you did was change some voxels from hippocampus to amygdala?

Hi Bruce,

Sorry, these were .tifs. Now they are...

Thanks

      what format are these in? Can you include extensions in the

            Hi Bruce,

            At the moment we are interested in the volumes and
            thus we checked and
            corrected the aseg-file (corrections done as
            described in the
            RecommendedReconstructions).
            In the first attachment you can see the incorrect
            automatic segementation of
            the hippocampus and in the second what it looked
            like after our corrections,
            but before the new recon with the giant defect.

            Cheerio,
            Thomas

                  Hi Thomas

                  when you say errors in the hippocampus do you
            mean the aseg or
                  the surfaces? If the surfaces, don't worry
            about them as they
                  are not used in the hippocampal region. You
            are probably
                  connecting the temporal lobe to the main body
            of the white
                  matter creating a giant defect.

                        Dear Freesurfer experts,

                        We are using FS 5.1 and have several

                        The error log says in all cases that
            there is
                        something wrong with the
                        cerebellum. When we open the ?h
            inflated.nofix file
                        then we see the
                        cerebellum added (see attached file) in
            the
                        hemisphere we made the edits. 

                         We have no clue if or what we are doing
            wrong and
                        here are the steps we
                        did:

                         - open the files (tkmedit subject
            norm.mgz
                        -aseg.mgz 

                        - Tool -> Configure Segmentation Brush
            info ->
                        select the hippocampus -> add
                        voxels 

                        - File -> save segmentation

                        - run recon with "recon-all -autorecon2
            -noaseg
                        –autorecon3 -subjid subject
                        -nuintensitycor-3T"

                        So far we had no problems with our
            subjects for all
                        the previous steps
                        (recon after wm, pial, .... edits) and
            it did run
                        smoothly.


                        Any help would be greatly appreciated.
