Hi bruce, my goal is to obtain a 3D surface of the hippocampal region for a visual comparison with a manual segmentation made by a neuroradiologist. Today I managed to extract the volume with mri_binarize but I can't transform it in a surface that tkurfer can visualize. For that I try to use mri_vol2surf but I obtain a surface with 0 vertices. Can you help me?? Cheers Leonardo

Hi Leonardo,
you just want to visualize it? Can you explain your goals a bit better? You could view it in freeview as an isosurface if you wanted. Ruopeng: is there wiki documentation for this?
cheers Bruce

Hi Bruce, Thanks for your attention, Can you write for me a sample line where I want to compute a 3D volume of the hippocampal? And I can show it with tksurfer? Thanks Leonardo

Hi Leonardo,
the outputs are listed on our wiki. If you want to extract a single structure you can use mri_binarize using the indices in the $FREESURFER_HOME/FreeSurferColorLUT.txt file.

Hi, after the segmentation process, we obtain a lots of file that I can't understand what they represent. Infact I know the mean of the file
aseg.mgz
(that is a mask of the segmentation) and norm.mgz but for example I can't understand the difference between brainmask.mgz and brainmask_auto.mgz.
Can
you help me with a list of the output? And can I obtain the volume
rendering
of only one part of the segmented structure? (es. Hippocampal)??
Thanks for your help
Leonardo
