Cuffdiff2 performs differential transcript abundance analysis for two or more RNA-Seq samples. However, Cuffdiff2 by default refrains from performing significance tests (Jensen-Shannon) when one of the conditions involved has fewer than three replicates for computing differential splicing, CDS switching, and promoter switching analyses. The "Cuffdiff2 with JS option" specifically addresses this by providing option to specify the number of replicates that will allow Cuffdiff2 to compute the JS tests for these analyses.

Quick Start

  • To use Cuffdiff2 with JS option
    • import your BAM files and your GTF file
