I'm a graduate student from the Ceará State University in Brazil, and my dissertation is about gene expression and eigengenes. I'm new to this field and I'm learning everyday about this topic.
For my dissertation I'm using the R package WGCNA to build gene networks and eigengene modules. The gene expression data I'm using is from an ArrayExpress MAGE-TAB file and here is my problem.
The MAGE-TAB file is a tab-delimited file, while the WGCNA only reads comma-delimited files, as far as I can tell. How can I read this file in the R environment?
I did several different tutorials to learn how to use the WGCNA, but I can't find a way to read this file so I can start building my gene network.
I really appreciate all the help I can get!
