Hi, I have some question on mri_segstats

1. --seg-erode Nerodes

Is it the size of the window for erosion?

I'm not sure what you mean. Nerodes is the number of recursive 1 voxel erosions.

2. --robust percent

Is it the percentage of tissue in each voxel?

It computes a "trimmed" mean/std in each ROI by excluding the top and bottom X% intensities.

3. If I want to combine Left and Right together and calculate the

statistics, for example the mean and std of the "Left/Right Caudate", how to do that?

Create a new segmentation mask with mri_binarize --i aseg.mgz --match 11 50 --o lrcaudate.mgz then run mri_segstats --seg lrcaudate.mgz --id 1 ... doug

Thank you, Fang
