Input Specifications
All submitted imaging data must comply with the input specifications detailed below. Any datasets that fail to meet these requirements will be deemed unsuitable for processing and rejected.
The required MRI sequence is a diffusion-weighted, single-shot spin echo-planar imaging (EPI) acquisition with whole-brain coverage.
