Hi,
I would like to register one slice of a subject's low res EPI data to his high res MPRAGE,
however I'm not sure what the best strategy would be. The major issue is that the single
slice EPI was taken at a different angle than the MPRAGE. The images that I have are:
1) Single slice EPI at level of hippocampus taken at an unknown angle (oriented so that it
spans the length of the hippocampus)
2) MPRAGE with slices parallel to AC-PC axis
3) fMRI 4D functional image with slices parallel to AC-PC axis
It was suggested that I register the MPRAGE to the single slice EPI using FLIRT w/ 12 DOF,
but I do not know if I should register a high res image to a low res one, and with affine
transformation at that.
Any help (with corresponding rationale) would be greatly appreciated.
