Dear freesurfer experts,

I am using freesurfer to analyze some fMRI data collected on two monkeys. My runs have a partial field of view, since just the posterior part of the brain was scanned. Unfortunately, no full-head EPI was collected. The registration between the processed functional data and the T1 is bad. All the values in the register.dof6.mincost file are above 0.8 and also visually I can see some mismatch. I though to run bbregister, could you suggest me which is the best procedure and which steps of the preprocessing I should re-run after?

Thanks
