External Email - Use Caution
Thank you! Unfortunately, I don't have any whole brain scan. I registered the template and all the runs with tkregisterfv and the I run bbregsiter. Now, should I just re-run selxavg3-sess?
Thanks Best

And you only have partial field of view fmri data on that day? No whole brain localizer? Really, any whole-brain volume will do. If you do not, then you'll have to initialize the bbr registration by hand, which is a bit of a pain. You'd run something like tkregisterfv --mov template.nii.gz --init-header --reg manual.reg.lta --surfs Then adjust the registration to be within 5mm of being right. Then run bbregister using that registration as the --init-reg If you have other scans where you have both the partial FoV and a whole brain, you might be able to get an init reg by registering the partial FoVs from different days. good luck

Unfortunately, I have only 3 mprage scans that were collected in another day but no whole-head functional data.

Do you have any scan that was acquired at the same time that is whole head? Any scan will do. If so, you can run register-sess using the -bbr-int option (or bbregister directly). Eg, if the anatomical was acquired at the same time, then, to use register-sess, create a folder in the session folder called anatomical/001 and put the anatomical in there (eg, anat.nii.gz), then use -bbr-int anatomical anat On 11/26/2018 02:58 PM, Francesca Strappini wrote: > > External Email - Use Caution > > Dear freesurfer experts, > > I am using freesurfer to analyze some fMRI data collected on two > monkeys.
