Abstract: Highlights•Group analysis of diffusion weighted MRI does not capitalize on all acquired volumes.•Detect voxelwise group differences and correlations by analysis of the ODFs.•Low-Rank plus Sparse Matrix decomposition to avoid outlier bias.•Replication of established association between white matter and BMI in HCP dataset.•Correlation of brain structure with fluid intelligence and episodic memory in HCP.
