Hi,
I would like to use 3dAllineate to coregister and spatially normalize EPI data.
I have a series of four images:
low-res EPI, 38 slices
low-res anatomical, 38 slices (same prescription as above)
high-res anatomical (124 slices)
standard template (e.g. ICBM-452)
I want to align as follows:
1. EPI ---> low-res anatomical
2. low-res anatomical --> high-res anatomical
3. high-res-anatomical --> standard
then I want to concatenate transformation matrices 1, 2, and 3 to get EPI --> standard
cat_matvec seems to be the program to use, but it does not seem to compatible with the output of "-1Dfile" from 3dAllineate.
Note I'm using NIFTI files for all steps but perhaps the answer is that I should be using BRIKs.
any ideas?
thanks,
Brad Buchsbaum
