Hi Bruce,
Many thanks again for your help. So just to make sure that I understood corect:
is better to use the talairach.m3z win my make_average_subject?
I was reading that the talairach coordinate is based on talairach.xfm (unless
changed with --xform) so your suggestion was to change it to talairach.m3z?
Many thanks.
Antonella

Hi Antonella
talairach.lta and .xfm are linear transforms to a Talairach coordinate
system. The .m3z is a nonlinear morph and will give you much higher
anatomical resolution.
cheers
Bruce
