Hi,
My previous question seems misleading. Here is what I want to do.
I have a labeled volume by mri_watershed, which classifies 6 tissue types and an exterior (i.e. background). I want to have a labeled volume without the exterior.
Thanks, Seok
If you mean save the screenshot to an image without the background ( the background is transparent), you can do so with the free GIMP. The tool is in one of the menus and it's called "Select by Color", click the black portion and cut it.
Save it to an image format which understands transparency ( PNG or TIFF )

what do you mean to save it without the background? Those voxels have to have some value.

Hi,
I want to remove the background 0 in the segmented volume like aseg.mgz, and saved the volume without the background. What is the simplest way to do it?
Best, Seok
