  • Annotation of SNPs

    Sorry if this is a really obvious question - I feel like there has to be an easy answer that I am just overlooking. I've used SAMtools mpileup to call SNPs in my RNAseq data. The SNPs are then listed by chromosome and position. How do annotate them so that the gene and whether they are intronic or exonic is matched with the SNP?

    Thanks for any help you all can give me!

    Wise enough not to reinvent the wheel and try the following tools:

    snpEff http://snpeff.sourceforge.net/
    annovar http://www.openbioinformatics.org/annovar/


    snpEff has a larger choice of reference annotation databases and supports the pileup format. It also supports VCF format.

      Current Approaches to Protein Sequencing
      by seqadmin


      Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

      Strategies for Sequencing Challenging Samples
      by seqadmin


      Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
