> 3) Segmenting CC( 10 mm thickness) in the flirted FA map.
> 4) Getting the converted matrix file using convert_xfm(convert_xfm -omat dti_FA_flirt_converted.mat -inverse dti_FA_flirt.mat).
> 5) Getting CC mask in the original FA map using flirt.
> flirt -in CC_mask -ref dti_FA.nii.gz -applyxfm -init dti_FA_flirt_converted.mat -out CC_mask_original

> But the CC mask in the original space( FA map) is incomplete. Is -applyxfm not fit for DTI image?
