I don't currently have any suggestions, although there are bits of code
in the HDW toolbox of SPM5 that will compute Jacobians of such dense
deformations (spm_def2det).
It's time for me to do a bit more work on the Deformations tools of SPM5
in order to increase their flexibility. Because of some new stuff that
I've been working on, this tool is likely to become much more useful.
Best regards,

Subject: [SPM] normalization
Dear SPMers,
my problem concerns MR normalization, with the Deformations or
Normalization
utilities.
I would need to combine two deformations defined by two parameter files,
as
allowed by the Deformations utility, but I would also need to modulate
the
images, preserving amount.
As far as I know, the Deformations tool does not allow to modulate.
Does anyone has any suggestion?! It would work, for exemple, if the
Deformations utility would allow to save a resulting deformation of the
two
deformations combined, and then use that as parameter file for
normalizing:
however, if I understood correctly, the Deformation utility gives as
output
file just image files, and no parameter .mat file.
thank you all in advance
Valentina
