Hi Freesurfers!

I am trying to merge a L and R hippocampal mask derived from fsl FIRST. I have binarized the masks (using the --match flag) but when I try to merge them (mri_binarize --i <L hippocampal mask> --merge <R hippocampal mask> --min --max --o <merged mask>) but the output merged mask is blank. Should I be specifying the min/max differently or is there another way to merge the two masks more accurately?

Cheers,

Annabel
