The min/max/etc are the voxel wise measures. When you use --accumulate, it sums all the voxels but does not divide by the number of voxels, so you get a number much larger than any one voxel doug On 9/3/14 9:44 PM, SHAHIN NASR wrote: Hi Surfers, I want to measure the average amount

[Freesurfer] Average myelination within ROI

2014-09-03 Thread SHAHIN NASR
Hi Surfers, I want to measure the average amount of myelinations within my ROI(s), I have already generated my myelination maps on surfaces (e.g. lh.myelin_ProjFrac0p5.nii ). Then I used mri_segstats as below: mri_segstats --i lh.myelin_ProjFrac0p5.nii --slabel SBJ_001 lh lh.V1 --sum
