    SNPEff warnings for GRCm38

    Hello everyone,

    I'm attempting to annotate a VCF file using SNPEff. The annotation seems to be working fine, but I'm concerned about the number of warnings that I'm getting.

    Exerpt from the verbose output:
    WARNINGS: Some warning were detected
    Warning type Number of warnings
    INFO_REALIGN_3_PRIME 133110
    WARNING_TRANSCRIPT_INCOMPLETE 115950

    I checked into these warnings in the SNPEff documentation, and it seems like they may indicate problems with the reference, but I'm using SNPEff's own GRCm38 reference.
    I thought part of the problem might stem from the fact that my VCFs are mm10, not GRCm38 (same build I know, but with different chromosome ids), so I tried changing the chromosome ids (e.g. chr1 to 1) but I got the same warnings.

    I'm sure I must be overlooking something obvious but I can't determine what.

    Can I just ignore these warnings and proceed with the resulting annotation? Or should I filter out the variants that are flagged with warnings (~25% of the variants)?

    Thanks.

    16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
    by SEQadmin2




    NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...

    Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
    by SEQadmin2



    Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

    Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating
