The three overlap measures are the following: * '''relative volume difference''' = 2*(|A|-|B|)/|A|+|B| `(the volume difference normalized by the mean)` * '''relative volume overlap (Dice)''' = 2*|A-B|/|A|+|B| `(the intersection over the mean of the segmentation volumes)` * '''relative volume overlap (Jaccard)''' = |A-B|/|A+B| `(the intersection over the union of the segmentation volumes)` Note, that the label files (e.g. aseg.mgz) need to be in a common space. You can use [[mri_convert]] with -rt nearest and -at to apply a transform to the segmentations. = Examples = = References = None = Author/s = LillaZollei
