mri_compute_seg_overlap - compute coefficents of overlap
mri_compute_seg_overlap [<options>] segvol1 segvol2
This program compares two segmentation volumes and computes the Dice and Jaccard Coefficients. It considers nine major structures (label numbers):
L/R Hippocampus (17,53)
L/R Caudate (11,50)
L/R Putamen (12,51)
L/R Pallidum (13,52)
L/R Amygdala (18,54)
L/R Thalamus_Proper (10,49)
L/R Lateral_Ventricle (75,76)
Third and Fourth Ventricles (14,15)
L/R Inf_Lat_Vent (5,44)
Argument | Explanation |
---|---|
segvol1 | first segmentation volume |
segvol2 | second segmentation volume |
Argument | Explanation |
---|---|
-log filename | log file for individual Dice |
-mlog filename | log file for mean Dice |
-slog filename | log file for std Dice |
-olog | log file for overall Dice |
mri_compute_seg_overlap manual_seg.mgz aseg.mgz
Used to compare the quality of the automatic segmentation with a manual segmentation. A Dice of 0.85 is about average.
