You can use flirt -applyisoxfm for this. I
don’t know if spline interpolation is in the 4.1.9 version of FLIRT, but it
doesn’t seem to work with -applyisoxfm.
Peace,

Subject: [FSL] resample image data
Hi
FSL users,
I
am wondering how to resample an image by any arbitrary factor, and keep the
same centering? fslmaths -subsamp2 only allows for a factor of 2.
For
instance, I’d like to resample my high-res atlas image from 1x1x1 mm to 3x3x3
mm, so that when I register my filtered_func_data to my atlas, I can use my
atlas_333 image as reference, and my func data will be aligned and in 333
space.
Thanks
very much for any insight,
David
