Dear FSL experts, Is b0 unwrapping typically recommended? If yes, I find that it is unchecked by default and want to understand why. Also, it looks like a fieldmap is required. Is that something I can generate from the structural or functional scan per se? If yes, can you please advise the typical procedure to obtain a fieldmap? Much appreciated!
