  • Statistical Analyses of illumina Miseq 250PE Data

    Hello everyone !
    I am a french PhD student in biology.

    I am working on the impact of physicochemicals parameters on the composition of bacterial communities in natural breeding sites of mosquitoes larvae.
    I collected 100 samples of breeding sites water, I measured their parameters( pH, salinity...) and by illumina Miseq sequençing i determined the bacterial communities composition of my 100 samples .
    With these sequencing data I made an unifrac unweighted analysis and it clearly appears 2 clusters in PcoA.
    I am new in the field of metagenomics.
    I don't know which multivariate statistical tests to use (RDA, CCA, PERMANOVA?) in order to determine which physicochemicals variables explains the 2 clusters.
    I thank you in advance for your reply.
    best regards
    hery

    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...
