I think this is not a MarsBaR question, but an SPM question (took the
liberty of editing the subject line).
Which images you choose to coregister to is really up to you. I think
most people user the functional image as target, structural as source,
merely for simplicity. For example, if you chose the structural as
target, and functional as source, you would also have to select all
your functional images for that subjects as 'other images' in the
ensuing dialog,
Best,
Matthew
