functional connectivity

when I overlay individual FCZMap to the T1 image, how can I choose the threshold of z score? Another question is which side is the left of structure,i am a little confused of this!thank you!


You can perform T test on zFCMaps, then you can set a P or T threshold on the statistical maps.
If you just have zFCMap of one subject, then the result is just for visual inspection only.
REST Slice Viewer display results in Radiology convention, i.e., the left side of the figure means the right hemisphere (If you data are NIFTI images, e.g., preprocessed by SPM5 or above)
Best wishes!
