Hi,
One additional point here - as there's also the script, featregapply.
This allows you to update either example_func2highres.mat
or highres2standard.mat (or both) in a .feat/reg directory and
then make everything else consistent with this. By running the
script it will fix all the other transforms (e.g.
example_func2standard.mat)
by using the newly supplied ones and will also update the registration
images, so that the feat report page will also be up-to-date.
All the best,
Mark
