Hello there, I am really fascinated by the possibility to start developing a very simple tool for analysing networks, given a list of genes. firstly, I would like to stress that the aim is not to publish but just understand the basics needed to get into grip with this tool.
Before posting, I have read at this tutorial by Kevin and I would like to learn more about this. More precisely, I would like to understand how to study likely correlation between genes differentially expressed, if that makes any sense to you? In other words, where to actually start from?

Limma Package For Differential Expression Between Control And Stress

just a thought but my understanding is that a correlation network built with differentially expressed gene is less informative than a simple heatmap with hierarchical clustering done for both the rows and the columns.
I am more generally interested by determining how to mathematically calculate correlation between genes and how, from there, create a basic network structure.
This is old but it is good start: link
