  • PAN and CORE genome analysis

    Hi,
    I have an OTU biom file (obtained from Closed reference QIIME 1.8.0 v) contains 65 samples, I am trying to do analysis for PAN/CORE genome.
    I have filtered out the taxonomy from the abundance file (with particular threshold, lets say 60 %), now i have an taxonomy column only in file from all the 65 samples (with threshold 60%), Is there is a way where i can do the functional annotation for it ?

    Any server/ software is there which can do that ?

    Any suggestions ?

    Best !

    Hi,

    I think you did 16S sequencing. If that is the case, maybe you are misunderstanding the meaning of CORE / PAN genome.

    CORE genome is the set of genes shared by all your organisms. PAN genome is the CORE genome plus the accessory genome. To build a CORE or PAN genome you have to have the gene sequences of your organisms. In 16S analysis you only get the 16S ribosomal RNA, you don't have the sequences of the genes.

    There are some tools to predict functional content based on 16S reads, like picrust https://picrust.github.com/picrust/

      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...
