WebDec 18, 2009 · There are two natural measures of relative expression: the fraction of transcripts and the fraction of nucleotides of the transcriptome made up by a given gene or isoform. For isoform i, we will denote these two quantities by τ i and ν i, respectively. At the isoform level, these quantities are related by the equations (1) (2)
