Actually, you might be able to do it this way.

first, combine the surfaces with

mris_convert --combinesurfs lh.white rh.white lh+rh.white

next, combine the overlays in matlab, something like

lh = MRIread('lh.overlay.mgz');

rh = MRIread('rh.overlay.mgz');

lhrh = lh; lhrh.vol = [lh.vol rh.vol]; MRIwrite(lhrh,'lh+rh.overlay.mgz');

Hi Joao, please remember to send to the list. We don't have anything to merge two hemis together. Manybe the other software has this functionality.

Hi Douglass,

thank you for your response.

I created two surfaces overlay files like this:

lh.mgz rh.mgz

I can load and view the information using FreeView.

I need to merge these files as a single surface file to load them together at the same time in another software.

This other software accepts Freesurfer ASC, Freesurfer BINARY, Text files and Gifti.

Do you mind to give me a hint in how I could accomplish this?

thank you very much,

best regards,

João V. Dornas
