Dear Aser,

The devil's in the detail. Try the methods for constructing a symmetrical template (and performing an asymmetry analysis) in the following paper by Didelot et al.:

Good luck,

All the best,

Alexander

Hi all,

If I want to compare right versus left in the brain, should I use a symmetric template if yes how I can do this or where I find it?

I could manage to reorient different right contrast images or left to be in the opposite side. But I am not sure how to do this in the template. Can you guide me please   

Regards,

ASer
