  • cuffdiff log2 value

    Hi,

    I am analyzing my RNA-Seq data. After running cuffdiff, I got a list of differentially expressed transcrpts or genes.

    As far as I know, log2 value = fold change. However, there are minus values. Is this possible?? log2 value can not be minus. Did I miss something??



    Looking forward to your help.

    Thanks in advance.

    Best

    The log2 value can most definitely be negative. Why not?

      Try log2(0.5) and log2(2). Log2 scale is convenient.
