    BEDTools has a coverage function. It will tell you how many bases are covered at each depth.

  • How can I estimate overall coverage against a reference database?

    I'm doing de novo assembly on RNA-seq data and I do a stand-alone BLAST against a reference transcriptome. I want to know how much of my assembly aligned, preferably as a percentage so I can estimate quality and have simple statistics to present along with the usual average and median contig lengths-

    Velvet-Oases 6.3%
    Trinity 7.9%

    etc. Is there a tool out there that will estimate how much of a reference database I have covered? Essentially I could add up the lengths of each aligned transcript and divide by the length of all the reference transcripts....not sure if this makes sense, but I could use some advice.

    Exploring the Dynamics of the Tumor Microenvironment
    by seqadmin




    The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

    Exploring Human Diversity Through Large-Scale Omics
    by seqadmin


    In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
