Figure 3.
A visual comparison of spatial normalization with the different software packages, by averaging 198 normalized T1 volumes. (A) MNI template, (B) SPM Normalize average normalized T1 volume, (C) SPM Segment average normalized T1 volume, (D) FSL average normalized T1 volume, (E) AFNI average normalized T1 volume, (F) BROCCOLI average normalized T1 volume. Note that AFNI uses a combination of cubic, quintic, and sinc interpolation as default, while SPM, FSL, and BROCCOLI all use linear interpolation as default.
