    Cuffdiff is confusing gene expression for splicing

    Hello all,

    I've been using the tuxedo suite for a while but I recently ran into a weird problem when using cuffdiff to look at splicing. Cuffdiff generated a few thousand significant genes with AS between four of my samples.

    The problem is that most of the genes with "significant alternative splicing" only have one isoform and therefore could not even be alternatively spliced!

    The genes appear differentially expressed, but how could cufflinks think they have AS when they only have one isoform? These genes are showing up as significant in splicing.diff but when I examine them in isoforms.fpkm_tracking each only has one line.

    Did you find out why?

      Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.

      Nine Things a Sample Prep Scientist Thinks About Before Sequencing
      by SEQadmin2


      I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

      Here are nine questions we think about, in roughly the order they matter, before...
