Hi Andreia
you could certainly change our segmentation labels to just these 3 classes easily enough in matlab. Then we have tools for computing partial volume fractions (I think mri_compute_volume_fractions)

Hello list,
Following this email that I found in the archives:
"(...) For the segmentation, FS still works voxelwise, but it's objective is to identify each structure as a whole, whereas SPM and FSL/FAST attempt to classify each voxel as being GM, WM or CSF. A short description of the method in FS is here: http://surfer.nmr.mgh.harvard.edu/fswiki/FreeSurferAnalysisPipelineOverview#... You may want also to have a look at this paper: http://dx.doi.org/10.1016/S0896-6273(02)00569-X
Hope this helps!
All the best,

I need to obtain the different % of tissue (GM, WM and CSF) inside one defined voxel. Does FS has a file that can be exported to Matlab to then get these values? Or only FSL/FAST and SPM have this type of info?
