Hi Sammy,

You can use the dilate/erode filter without constraints. You can also create
an outside constraint mask by using invert mask, then modifying it as needed.
There may be other techniques to try, but I would need to know more about
what you are trying to do.

I forwarded the flipped nifti data that you shared earlier to one of our
developers. We hope to figure out what’s going on soon.
