Principal component analysis of MRI relative volumes in inbred mice. Brain regions included in analysis are available in Supplementary File 3 and Supplementary Fig. S3. Variance explained: PC1 = 23.2%, PC2 = 15.9% PC3 = 11.3%. A PCA, observations coloured by Genotype. B PCA points coloured by 3 clusters generated by unsupervised hierarchical clustering. Orange = Cluster 1, Green = Cluster 2, Purple = Cluster 3. C Bar graph describing the proportion of observations belonging to each Genotype in Clusters I, 2, and 3
