External Email - Use Caution
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.
