Author Posts July 22, 2019 at 1:52 pm #1865 randcrawParticipant When I save a mask it defaults to *.nii. When I specify *.hdr, it saves a *.img.gz file. When I uncompress that, I get a *.img.cdxr or somehting similar. Is there a way to simply save it as *.hdr and *.img? I’m using 19.a on MacOS Mojave.
