Whether FPKM values can be used to indicate the expression level of genes

Question

[Ginsea Chen]

Hi ALL

I have used Tophat -> cufflinks -> cummerbund to analyze interested gene expression levels among different tissues. I got plot expression levels for genes of interest with bar plots based on follows command:

> expressionBarplot(mygene)

The y lab of these plots was FPKM, so I want to know if these FPKM values can be use to indicate gene expression levels.

Thanks all!

Yes, that's kind of the point of FPKMs.
