It seems that only in dev version, mri_label2label supports dilation.

But I find that in 5.3, mris_label_calc is able to perform dilation too!

Hi Daniel,

yes, mri_label2label will do this, at least the current dev version and maybe 5.3:

mri_label2label | grep dilate --dilate N dilate the label N times before writing

cheers Bruce
