Hello everyone,

I am quite new to FreeSurfer and I have a doubt for the visualization of the data on a registered surface.

Is it enough to load in freeview the surface.reg with overlayed the data like in:

freeview -f lh.sphere.reg:overlay=lh.sulc

or 

freeview -f lh.sphere.reg:annot=aparc.annot

Doing like this the results do not change at all between subject and aligned subject and so I do not know wheter it was a problem in the registration itself or in the visualization.

Actually, my surface is not really lh.sphere.reg, but itis the output from the first step of CVS registration (the surface step); but anyway it is always in the format lh.xxx.sphere.reg.

Second question (less important):

I am trying to visualize in the same freeview window multiple spheres (subject, template and aligned subject) and I use the offset position flag to fix them at the right distance in the space.

Anyway, the spheres are not translated in the space with respect to the origin but roto-translated; so the spheres do not show the same face to the viewer but a slightly different one on each sphere.

Is there a way in Freeview to load the spheres at the same time and make them show the same face at the same moment?

Cheers

Mark
