摘要

•We compare 21 manual protocols for labeling hippocampal and parahippocampal subfields.•21 research groups applied their own manual segmentation protocol to the same anatomy.•Fuzzy similarity metrics used to quantify disagreement between protocols•Greatest disagreement is along the CA1/subiculum boundary, anterior hippocampus.•We propose a strategy for developing a harmonized segmentation protocol.
