ROI Atlas in AFNI


I am interested in manually selecting ROIs based on atlases in AFNI. I aligned my subject’s anatomical files using SSwarper and used the MNI152_2009_template_SSW.nii.gz template. With this, does it make sense for me to use the “TT_Daemon” atlas for segmenting the ROIs? If so, would I need to complete resolution conversion using 3dfractionize or 3dresample?

Thank you very much.


The Talairach daemon has many defects, so I tend to avoid that. Still if you absolutely must use, you can transform the atlas or regions extracted from it with the 3dfractionize approach in this previous post:,70173,80922#msg-80922
