I'm using the **Weighted Gene Coexpression Network Analysis** package (**WGCNA**) in **R** and I am trying to figure out how the **adjacency matrix** is defined.

**I understand how the correlation matrix is created along with why the power is used but adjacency matrices should be either 1 or 0.**

Why are there still continuous values? How does it choose a cutoff later?

I can understand that it's maybe a weighted adjacency matrix but there isn't an option to make it binary and that is needed for the topological overlap matrix calculation (TOM)
