Dear Freesurfer:

I am now working in converting cortical labels from freesurfer to volumetric 
masks. First i gained the registration matrix  by bbregister, then applied 
those matrix to tranform ROI labels into native space using label2vol. However, 
when i got the final .NII results, both of them turn out to be L-R fliped. 
(left ROI on the right hemisphere). From my understanding, freesurfer will 
automaticly recognize the head direction of the original T1 images and my 
original T1 data contains the flip information due to the way we scaned. 

So why this happen? By the way, the recon-all results did good.
Thank you very much!   

best,
Cowen
