[Mristudio-users] questions about nonlinear normalization with DiffeoMap

[susumu mori]

Before you run LDDMM, you first have to do linear registration using AIR.
At this point, if you use one of our atlases, your images are automatically
resampled to 171x217x171 / 1x1x1mm matrix.
This step is not absolutely necessary, depending on how you want to do the
normalization, but LDDMM does require your images to have isotropic
resolution.
