Hi,
I am testing cufflinks with two different normalization methods: total-hits-norm and compatible-hits-norm. My understanding is that the only difference between these two methods is the FPKM denominator: one is the number of all hits, the other is the number of hits within the reference GTF. So the ratios of FPKM values calculated by two methods should be a single fixed number, which is the ratio of hits. But, the ratios I got is a distribution. Anybody have an idea of the exact meaning of compatible-hits-norm? Thanks!
