The mask has to be a 3-dimensional binary volume. I'm not sure there is
a way to do what (I think) you want to do (would not make sense).

Dear freesurfer experts,
I would like to ask you about the mris_fwhm script. What does the flag
"--mask" exactly do? Suppose I would like to compute the effective
smoothness of an mri dataset. Some subjects have zeros in some
vertices, but instead of using the prune option, I would like to use
all the available signal, so I have to use a different mask for every
subject. Would the option mask do the job in that case and would
accept the multidimensional mask? Or rather the "--mask" option
expects for a single (not multidimensional) mask?
Any insight would be greatly appreciated. Thanks in advance,
Eduard Vilaplana.
