iSurf BrainView now available for Windows 8 {Disarmed}
by Pedro Paulo de Magalhães Oliveira Junior 27 Mar '13

27 Mar '13

Today Microsoft approved iSurf BrainView version for Windows 8 Tablets and computers. It's a free App. http://apps.microsoft.com/windows/en-us/app/brainview/be2623f5-c5e3-4295-a2… BrainView is a Brain MRI tutor based on the MRI automatic segmentation produced by FreeSurfer. FreeSurfer is a software package developed by investigators at the Athinoula A. Martinos Center for Biomedical Imaging. This App uses its automatic segmentation to produce an automatic atlas of neuroimaging based on T1 MRI Images. It also displays 3D accurate models of brain cortex with automatic structure labeling. A great tool for teaching brain MRI and for learning neuroanatomy. For more reference on the educational use of iSurf BrainView: Oliveira Jr, PPM; Fischl, Bruce; Amaro, Edson "Teaching neuroanatomy using Iphone and IPad. In: Human Brain Mapping, 2011, Quebec, CA.

Re: [Freesurfer] Merging PArcellation labels
by Laura M. Tully 26 Mar '13

26 Mar '13

it sounds like you want a different parcellation of the lateral prefrontal cortex than what is offered by the default atlas (aparc, AKA the desikan atlas) - I suggest you load in ?h.aparc.a2009s.annot (aka the destrieux atlas) as your annotation in tksurfer and select the annotations of the PFC that you want from there and save as labels. The aparc.a2009 annotation offers a more fine grained parcellation of the PFC - e.g. you can get the DLPFC by merging the middle frontal gyrus & middle frontal sulcus parcellations.

sort labels by lobes
by Anna Varentsova 26 Mar '13

26 Mar '13

Dear all, I have a brain segmented with Freesurfer 2009 and a list with label description looking like this: ... 11101 ctx_lh_G_and_S_frontomargin 12101 ctx_rh_G_and_S_frontomargin 11102 ctx_lh_G_and_S_occipital_inf 12102 ctx_rh_G_and_S_occipital_inf ... What is the best way to sort labels by lobes based on the name or the number? Are there any publications with this information or a table somewhere on Freesurfer web-page? Sincerely yours, Anna Varentsova

subcortical segmentation
by Joshua Lee 26 Mar '13

26 Mar '13

A subcortical segmentation error sometimes get Freesurfer (v 5.1) is cortical areas coming over into the hippocampus, ignoring the wm inferior and lateral to the hippocmapus (coronal). See attached png. Will adding wm control points help, or do they not inform the aseg segmentation. What is the best way to (non-manually) fix this kind of issue? - Josh

Fwd: Brodmann area thickness, surface area and volume

Hello list! Any suggestions on what I may be doing wrong? Thanks!

I've added the 5.2 BAxxx.threshold.label to my 5.0 fsaverage and run the recon-all BA labels command.

Am I missing something? Do I need to run any other command so to the threshold have effect?
