Dear Alexander,
the hippocampal box is an image 30 x 70 x 30, cut from an image MRI 180 x 140 x 180 of the entire brain
Have a nice dayRosangela

Dear Rosangela,
Thanks. I am not quite clear where your hippocampus "box" comes from, then - maybe you can explain a bit more?
Normally people will define regions of interest directly on their images of interest, or get them from existing atlases. In order to use any region of interest, you would need to bring it into register with the tissue probability maps you want to use.
Afterwards, you can combine your ROIs with any TPMs you like.
WBW,
Alexander
