Dear FSL-experts,
I recently ran a script multiplying the same binarized
mask with several normalized dti_FA images (fslmaths
mask.nii.gz -mul norm_dti_FA.nii.gz output.nii.gz). In
most of the cases, I got what I wanted: An .nii.gz with a
cutout from my normalized dti_FA image. However in some of
the cases (which seemed to be totally random), I got a
binarized mask which included only high-FA voxels and thus
covered just a part of my original mask. Changing the
order of my command (fslmaths norm_dti_FA.nii.gz -mul
mask.nii.gz output.nii.gz) solves this problem. However, I
was wondering whether this is a bug or why the order of my
multiplication makes a difference.
Thank you very much. Your help is greatly appreciated.
Best,
Theodor
