Hi Jorge,
the creation of the template is a 2-stage process in which we morph everyone to a randomly selected individual, regenerate an atlas, then reregister. All morphing these days is done with the same set of parameters, which are pretty rigid (much more constrained morph than it used to be in accordance with our recent findings that these parameter optimize the alignment of the architectonics):
l_dist = 5.0 // metric preservation term l_corr = 1.0 ; // folding likelihood (correlation) term l_parea = 0.2 ; // area preservation term
cheers, Bruce

Hello all
I would like to know the values of the metric distortion and deformation
parameters (of the spherical registration algorithm) when creating an average subject and when registering the underlying population to the previous average.
That is to say: What is the difference in the spherical morphing between
the creation of the average subject and the alignment of the individual subjects to that average?
In advance thank you
