Fold Change with DESeq2

Question

[tweiskittel94]

I have a very simple matrix of pairs of columns showing tumor RNAseq raw counts and normal tissue raw counts and rows with Ensembl IDs. I am trying to use the DESeq2 to get fold change between tumor and normal tissue. All of the DESeq tutorials or examples have much more complicated matrices with data that is structured completely differently. Does anyone have an idea of how I can use DESeq2 to get fold change from my simple matrix?

there are several more columns, but that is the first pair with TCGA-E9-A3QA-01A-61R-A22K-07 being tumor and TCGA-EW-A1P6-01A-11R-A144-07 being tissue normal

I added markup to your post for increased readability. You can do this by selecting the text and clicking the 101010 button. When you compose or edit a post that button is in your toolbar, see image below:

Looks like a normal count matrix to me. What do you think is "much more complicated" in the examples you have seen? Please give a link to it.
