I am working with Co-expression network analysis using WGCNA. I am however unable to understand how to create the "trait data" input file for the WGCNA. I have four sample from 2 cultivars with 3 replicates each.
Each sample that goes into WGCNA should have it's own set of traits in the trait table that are unique to it. The traits can be experimental treatments that they were exposed to or variables that you measured (e.g. respiration) from that measured from that sample.
