Hi all,
bbregister --init-best always produces "ERROR: cannot spec an init method with --init-best", because InitCoreg is defined as 1 by default, and never set to 0 by --init-best. (Setting something else that unsets InitCoreg will trigger the same error.)
Example, given SUBJ and EPI:
$ bbregister --init-best --s $SUBJ --mov $EPI --o ${EPI%.nii.gz}_bbr.nii.gz --reg ${EPI%.nii.gz}_bbr.dat
ERROR: cannot spec an init method with --init-best
Using FreeSurfer 6.0 release installed on an Ubuntu 16.04 machine.
Thanks,
Chris
