Hi
   In monkey fmri, we usually have to do the functional-anatomical registration manually since bbregister doesn't work very well.
    It was easy in version 4.5 since we usually used just one run for registration.  In version 5.1 we can use per-run option to improve registration but I am wondering how can we use it in monkey fmri? Should we register each run separately? Then how can we combine those individual registration files to generate the final registration file.
