QC images generated by afni_proc.py for Ex. 2 focused on the motion and regression model setup when processing task-based FMRI. Panel A shows the Enorm and outlier fraction plots across time, which are used for time point censoring. The dashed lines show the thresholds for each quantity, and the red bands highlight the location of any volumes to be censored (here, only three volumes are censored). The “BC” and “AC” boxplots show distributions of each plotted parameter before and after censoring, respectively. The lower two panels show the “ideal” stimulus response based on the timing and chosen hemodynamic response function (HRF): B shows the sum of responses, and C shows each individual stimulus class. The red band of censoring is also displayed here, to reveal any cases of stimulus-correlated motion (which is also checked automatically in the “warns” section of the APQC HTML).
