We have another question that is very related, so I will ask that at the same time:
We have a region of interest defined on an individual subject's surface. How can Freesurfer translate that ROI into the coordinates of the original fmri data? It's clear to us how to get from fmri to the surface, but not the other way around. Thanks, Kathleen and Elise On 6/9/10 12:49 PM, "Dickinson, Annelise (NIH/NIMH) [F]" <dickins...@mail.nih.gov> wrote: Hi all, We have used mrivol2surf with the output of bbregister to transform an individual subject's fmri data into the coordinates of the anatomical used to generate that subject's surface. We are happy with the accuracy of this registration. However, we are stuck because as far as we know bbregister only works in one direction, fmri to anatomical. We have a region of interest defined as a sphere around a coordinate in Talairach space. What we need to do is to translate that region of interest into the space of an individual subject's fmri data. How can Freesurfer do this? Any suggestions would be greatly appreciated!!
