3 questions about module membership vs gene significance

Question

[demoraesdiogo2017]

Hello

I have three questions about this figure

1. I know the correlation value is pretty low. But say I want a biomarker for adipocyte size. Would the gene pointed by the arrow be a candidate?

2. How do I get the name of the gene in the plot?

3. How do I plot this figure after I have done the consensus analysis? I was able to get to this by following the tutorial, but this image is only before the consensus analysis. I was not able to get it after. Is it possible?
