Does anybody have experience on how to create .BRIK files of data that stems from a split-sagittal acquisition? I have both, a T1 image and EPI data consisting of 14 sagittal slices, 7 in each hemisphere of the brain, and additionally an SPGR image of the entire brain. I would like to create a single BRIK file that has those 14 slices at the correct coordinates aligned to the SPGR.
My straight-forward solution has been so far to separate the T1 and EPI data according to the brain half they belong to and to create half-brain BRIKs. That works ok, but then I only can work with half a brain at a time. I could also add them together later in the process, but splitting them first and putting them back together seems rather costly.
Is there a way that, e.g. to3d can be used to inout the coordinates of both halves simultaneously?
Thanks,
Svenja.
