Hi Gabor,

sorry, I still don't know what you mean. The volume estimates in aseg.stats do include partial volume estimates. Do you mean to include only the volume of a structure that comes from partial volume voxels? Would that really be useful? For something like the hippocampus it will be a lot

Dear Bruce,

I think of a file which also shows the partial volume estimates for the segmented structures.

Thanks, Gabor

Dear Bruce,

Is there a file generated by freesurfer which stores the subcortical segmentations together with the information of partial volume estimates?

Thanks, Gabor

Hi Gabor

the partial volume estimates are not the probabilities. We could output p-values, but that won't give you partial volume estimates. Bruce On Thu, 15 May 2014, Gabor Perlaki wrote:

Dear Bruce,

I think of a probability map for each segmented structure, like the partial volume images for WM, GM and CSF in FSL. Is there anything like that in Freesurfer?

Thanks, Gabor
