--- Errata for Watanabe et al., Nature Communications, 4, 1370 (2013). ---
(1) "Inverse Gaussian model" should be replaced by "Gaussian model" throughout the text.
(2) "J_{i j sigma_i sigma_j}" on the right-hand side of equation (1) (right column on p.8) should be replaced by "J_{i j} sigma_i sigma_j", where the underscore denotes the subscript.
(3) In Supplementary Fig. 4 in Supplementary Information, the labels on the horizontal axis should be swapped. In other words, the pair of bars (one white bar and one gray bar) on the right corresponds to Binary MEM (not Trinary MEM). The two pairs of bars on the left correspond to Trinary MEM (not Binary MEM).
