Hi there,

I have looked a bit around for this question but i haven't managed to fully understand the answers. I have done a WGCNA analysis on my data which ended up identifying several modules of co-expressed genes. Now, I would like to calculate significance of the correlation between the eigengenes and the trait data to further narrow down on what is more interesting. My traits data however has two covariates: time points, which is divided in 3, 7 and 35 days and virus strains, which are divided in 5 groups (control included). As far as i understand it shouldn't be allowed to replace integers for each strain group in order to calculate some kind of correlation, or is it? What other statistical analysis could i perform?
