Results of running AFNI’s left-right flip check on several publicly available human datasets using afni_proc.py. Datasets were randomly assigned to a “flipped” group (anatomical volume left-right flipped before analysis) or to an “unflipped” group (no changes performed). For all datasets, the correct left-right flip results were found; these were verified visually using afni_proc.py’s automatically generated QC HTML (see Figure 2).
