Extended Data Fig. 4: Reconstruction accuracy achieved by geometric eigenmodes and PCA.

(a) Reconstruction accuracy of resting-state FC. (b) Comparison of the reconstruction accuracy of all 47 HCP task-contrast maps, which have been grouped here by broad types (Supplementary Information 2.1). wm = working memory. Each row represents a different task contrast. Red indicates superior performance for geometric eigenmodes. The asterisk denotes the contrast (that is, the seven key HCP task contrasts) within the relevant task used to train the PCA.
