Evaluation of beta-weights for general ability (GA). Beta-weights were calculated in the ARMS-1 sample with GA as the outcome of interest. (A) Manhattan plot, in logarithmic scale, showing the p-values of each connection. Connections are color coded according to the Gordon parcellation schema. Connections are color-coded by network assignment and ranked by the p-value of their beta-weight calculated in ARMS-1 for GA. The right-hand axis and thin gray horizontal lines denote the imposed thresholds evaluated to predict scores in the independent sample (ARMS-2). (B) Scatterplot showing the explained variance as a function of p-value per individual connection in the independent sample. (C) Explained variance calculated per network pair by summing all the connections within a given network pair. (D) Green line shows the explained variance per imposed threshold for the connections identified in the Manhattan plot (gray lines). Null data testing the specificity of the selected connections is shown in purple. At each threshold the PNRS approach was repeated 400 times after re-sorting connections randomly. Resulting predictions are shown as box plots where mean values are indicated as circles, the interquartile range is indicated in shaded purple and thin lines show the 2.5 % and 97.5 % of the distribution.
