Hi all, I converted a segmented image (with region labels 0 for background, 1 for cluster 1, etc) that was 16-bit int (short) to 8-bit int (char) with avwmaths++ segmented.nii segmentedBYTE.nii -odt char The segmented.nii has on enormous cluster in the parietal cortex, which has totally disappeared in the conversion. am I right in thinkning that in the conversion from 16-bit to 8-bit, all numbers are divided by 256? If not, what could be happening here? Cheers Alle Meije
