Hi Zhi Wang, To choose or not to choose the flip option in MRIcro it depends on which orientation (radiologic/neurologic) you want to consider. If your DICOM images are in radiologic format (left is right), you shouldn't choose this option and thus set defaults.analyze.flip to 1. If you want to use neurological format, you can mark the flip check box and also set defaults.analyze.flip to 0. Good luck! Gracián.
