    snpeff canonical transcript annotations: multiple annotations problem

    Hi,
    I'm using snpEff in my exome sequencing pipeline and I use -canon option to get only the canonical transcripts annotated for a particular variant. But eventhough I'm using the option, I can see there are multiple annotations for a single variant in the INFO field of the vcf file.

    Can somebody explain this to me please.

    Thanks in advance.

    I am seeing the same thing almost two years later and can't seem to make sense of it.

      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...

      From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
      by SEQadmin2


      Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


      The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
