Hi Freesurfer users,

I need to design a ROI map for my project. It has to be based on certain coordinates. The ideal is to draw a circle based on the coordinates in the Talairach space in Freesurfer, which I do not know how to achieve. The alternative is to draw a spherical cluster in fsl and convert it back to the Talairach space in Freesurfer, which I don't know how to do either. 

Any suggestions?

Many thanks
