Thank you for this important contribution to neuroimaging tools for analysis of older populations.  Am looking to confirm rsfMRI results previously obtained on an ADNI dataset with AFNI using MNI152 atlas.  Does anyone have experience applying MCALT in AFNI?  I may need just a bit of hand-holding here, but is it correct that in order to use ./MCALT_T1.nii it needs to be skullstripped first? - KAG
