Hi Lisa,

And FWIW, you can download it here:
http://packages.bic.mni.mcgill.ca/scripts/nlpfit
As Claude mentioned the fit config is really what makes this work
though, an example for ICBM fitting of brains that I use is like this:
spencer:~$ cat work/pipes/ANDI/bin/fit.10-modelfit.conf
# ICBM nlin conf
@conf = (
{'step' => 32, 'blur_fwhm' => 16, 'iterations' => 20},
{'step' => 16, 'blur_fwhm' => 8, 'iterations' => 20},
{'step' => 12, 'blur_fwhm' => 6, 'iterations' => 20},
{'step' => 8, 'blur_fwhm' => 4, 'iterations' => 20},
{'step' => 6, 'blur_fwhm' => 3, 'iterations' => 20},
);
Note that this may or may not work for your data. The config file here
describes a progression of fitting from 32mm step sizes down to 6mm
with varying blur parameters along the way.
