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 Jiwen
