Erratum for “Frequency-based brain networks: From a multiplex framework to a full multilayer description”

After the publication of our paper “Frequency-based brain networks: From a multiplex framework to a full multilayer description” (https://doi.org/10.1162/netn_a_00033), we discovered a labeling error in the main text when we refer to the colors of the plots in Figure 6. In Figure 6, we show the values of λ₂ that we obtain for four different network reconstructions from MEG data: a homogeneous multiplex network (black circles), a heterogeneous multiplex network (red circles), a homogeneous full multilayer network (orange circles), and a heterogeneous full multilayer network (blue circles).

This is an error only in labeling, which we wish to correct to prevent possible confusion. Everything else in our paper remains as before.

LIST OF CHANGES:

1. page 431, first full paragraph, first sentence:

   Now: “In Figure 6, we show the values of λ₂ that we obtain for four different network reconstructions based on the MEG data: a homogeneous multiplex network (black circles), a heterogeneous multiplex network (red circles), a homogeneous full multilayer network (blue circles), and a heterogeneous full multilayer network (cyan circles).”

   Correct: “In Figure 6, we show the values of λ₂ that we obtain for four different network reconstructions based on the MEG data: a homogeneous multiplex network (black circles), a heterogeneous multiplex network (red circles), a homogeneous full multilayer network (orange circles), and a heterogeneous full multilayer network (blue circles).”

2. page 432, paragraph that continues from the previous page, last sentence:

   Now: “Although it looks from the plot that the algebraic connectivities of the heterogeneous multilayer networks (cyan circles) and those of the homogeneous multiplex networks (black circles) may converge to the same value for large S_P, they eventually cross each other when we further increase S_P (not shown).”

   Correct: “Although it looks from the plot that the algebraic connectivities of the heterogeneous multilayer networks (blue circles) and those of the homogeneous multiplex networks (black circles) may converge to the same value for large S_P, they eventually cross each other when we further increase S_P (not shown).”
