Hi Jared,

yes, we have both volumetric and surface-based:

mris_hausdorff_dist usage: mris_hausdorff_dist [options] <surface> <label1> <label2> -a <annot name> compute pairwise HD between all annotations mri_hausdorff_dist USAGE: mri_hausdorff_dist <options> <vol1> <vol2> ... <output text file> where options are: -b <thresh> binarize input volumes with threshold <thresh> -g <sigma> blur the input image with Gaussian <sigma> -max compute the max of the min distances instead of the mean

cheers, Bruce

Hi freesurfer masters, I was wondering if freesurfer had a way of comparing two segmentations for surface differences, something along the lines of a Hausdorff distance or the symmetric mean absolute surface distance Cheers, Jared _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
