Abstract Tools available for reproducible, quantitative assessment of brain correspondence have been limited. We previously validated the anatomical fiducial (AFID) placement protocol point-based image registration with millimetric (mm) accuracy. In this data descriptor, we release curated AFID placements some most commonly used structural magnetic resonance imaging datasets and templates. The our accurate allows rapid quality control registration, teaching neuroanatomy, clinical...
