Dear experts,
Can guassian smoothing be used on FA maps?
I have diffusion maps ( FA, MD, AD, and RD) derived from the FSL pre processing pipeline using the tool ( FDT).
I am thinking of applying the following command on FA, MD, AD and RD
fslmaths <DTI_map.nii.gz > -kernel gauss 2.55 -fmean <DTI_map_sm6mm> -odt float
Can smoothing be used on DTI maps then including these smoothed maps in further analyses (e.g. TBSS)
Thank you
Jon
