Hello all:

I have a 12-slice, 16-echo T2 dataset which is currently ordered as: TE0(slice0..slice11), TE1(slice0..slice11),..., TE15(slice0..slice11). We need to reorder it to slice0(TE0, TE1,..., TE15), slice1(TE0, TE1,..., TE15),..., slice11(TE0, TE1,..., TE15). Is there an AFNI utility that can do this efficiently?

I'm a bit rusty with AFNI, so although I know I can "address" the TE dimension as [0], [1], ..., [15], I don't know how to "address" the slice dimension or how to "glue" everything back together -- 3dTcat? 3dbucket? 3dcalc? Any advice you could provide would be greatly appreciated!

Kind regards,
Jeremy Smith
