Hi Joel,
both the .m3z (nonlinear) and the .lta (linear) are transforms from the
subject to the atlas coordinate system, but all the labeling is done in
the subject space, so you should be set.
cheers,

Hello-
I'm running FreeSurfer v4.01on SUSE Linux
I'm interested in viewing the sub-cortical parcels, /mri/aseg.mgz, but
in the native MRI space. I see that the output of "CA Label" produces
a file that is fit to the "CA Normalize" step but I can't figure out
the transform that was used. Specifically, for CA Normalize, if I
look under /mri/transforms, and sort by time, I have both the
talairach.lta and talairach.m3z files, but neither will get me from
native to norm space (or vice-versa). Is there a transform file that
I'm missing or is this a process of intermediate steps to get from
native to norm space? Please help!
Thanks,
Joel
