Hello Bioconductor community!
I'm new to using these packages in R.
I am not working with gene expression data, but count data of amino acid sequences. I believe these packages provide the correct abstractions and methods to work with.
I have a number of different grouped samples (columns) with the same underlying proteins. Positive and negative controls are common and spiked into each sample. I have the row names for those.
I have run through calculating the logFC between sample groups, but this isn't what I actually want.
What I want to do is use these packages to run statistics on the fold change of a protein (gene) against the shared positive or negative controls, rather than between sample groups.
I think what I want to do is use the sample groupings to predict the protein-level dispersion, and then somehow either introduce a ratio to control into the glmFit design matrix, or new columns for the controls as new groups specifically in the design matrix.
I'm wondering if this seems feasible?
Warm regards.
I'm removing the DESeq2 tag, as it looks like you are asking an edgeR question. Generally, we encourage users to ask questions of particular developers, and avoid tagging multiple packages at once, to avoid extra notification burden on the developers.
