Normalize counts by CQN. By providing a biomart object, the systematic effect of GC content is removed and gene length (in bp) variation is accounted for. Genes with missing GC content or gene lengths will be removed from the counts matrix.
cqn(filtered_counts, biomart_results)A counts data frame with genes removed that have low expression.
Output of "sageseqr::get_biomart()". Gene Ids are
stored as rownames.
