Dear SPM Listmembers
I wondered if it is possible to run a non-linear deformation *without*
performing the affine-registration first? I know I can do it the other way
around, i.e. to run just an affine deformation (by setting the basis
functions to zero in the defaults). Alternatively, is there a way that I
can isolate the affine and nonlinear components of the deformation?
I wanted to use the 'Invert Deformations' part of the Deformations toolbox -
and to invert just the nonlinear part of the deformation.
I guess I could do a two-step process - so that I just do an affine
transformation first, and use these normalized images to create a new
*sn3d.mat file, from which to compute the nonlinear deformation field (and
its inverse) - but thought there might be a quicker way?
Many thanks in advance
Derek
