Hi Lisa, For quality control, there is a Quality Control module in DPABI ( http://rfmri.org/DPABI). For Normalization QC, the software pops up normalized T1, EPI, GM for each subject and a template image, with the boundaries overlayed. You can give a QC score and a QC comment, and then select them by QC scores.
