There is too much noise outside the brain, so I want to apply brain<br>
mask to eliminate the noise.<br>
I tried to use ROI editor to make brain mask, using skull strip. I<br>
obtained mask.nii on scrolldown box and saved it to a dat file.<br>
but I could not load it for tensor calculation. I found 'select a<br>
mask-image' option, but only subjectname.dat-0, subjectname.dat-1,<br>
...-2, ...-3 was available.<br>
how could I apply mask image for Tensor calculation?<br>
<br>
I would appreciate any comments.<br>
