  • Understanding ASV data

    Hi, I am new to bioinformatics and do not have much biology knowledge. I need to use some ASV (amplicon sequence variant) data, and I do not know where to begin to understand what the data means or how it is derived.

    ASV_1, ASV_2, ASV_3, ........, ASV_308, ASV_319, ASV_351, ASV_352
    2.3442, 1.49628 11.76248, ........, 0, 0, 0, 0
    5.343, 0, 13.3471, ........, 0, 0, 0, 0
    5.4518, 0, 14.58453, ........, 0, 0, 0, 0

    Please tell me, what are the column headers ASV_1, ASV_2, etc, and what do they mean? What are the values (i.e. the real numbers) supposed to indicate?

    What is "abundance" wrt ASV supposed to mean? Any links or pointers to papers or tutorials will be appreciated.

    Thanks,

    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...
