    How much data should I generate for metagenomics/metatranscriptomics?

    Hi, my lab is planning to do shotgun metagenomics and metatranscriptomics using Illumina platforms, we want to go for commercial sequencing since we don't have access to HiSeq machine. I'm a beginner in the NGS field and I'm now getting confused on the data size I should get.
    The samples come from built environment, what I want to know is the taxonomy and functional gene information from metagenomics and 'active' taxonomy and functioning gene information from metatranscriptomics. I've done a 16S rDNA amplicon sequencing with Illumina MiSeq using some of my DNA samples and they generally contain ~500 different bacteria at the genus level.
    The data the sequencing company can give me after sequencing is 'qualified clean data' which seems to be data that index primers are trimmed off and low quality reads are filtered out. The company is suggesting me to get a 3 GB clean data per sample for shotgun metagenomics and a 2-4 GB clean data per sample for metatranscriptomics RNA-seq. I checked for a few metagenomics papers which varies in the data size they acquire (from ~2GB to ~30GB and they do not say if they are raw or clean data).
    In this case, could anybody give me some suggestions or experience in approximately how much data (if possible the minimum), or 'clean data' might be enough for the above metagenomics and metatranscriptomics analysis, considering this is a built environment which might not be of high complexity?
    Thank you very very much!!!!

    Dear annaatobe,

    This is some information which might help you. Same kind of the problem i am also facing. No one tells that how much data is generated per sample. this information is provided to me by a service provider;

    ***300bp 515F bacterial, archaeal or fungal diversity PGM assays with nominal 15-20,000 reads/assay for $60/assay (any size project)
    ***2x300bp PE illumina 20,000 sequence diversity assays starting at $60/assay larger projects ($70/assay medium sized project, and $80/sample small.. (for projects < 10 assays per library, a $100 library fee is added) for nominal 20,000 reads/assay. (we do accept any size project)
    ***454 pyrosequencing 1x400bp diversity assays any size project starting at $90/assay for 3,000 nominal reads (any sized project)
    ***454 pyrosequencing 1x400bp diversity assays any size project starting at $160/assay for 10,000 nominal reads
    Shotgun services
    ***Communal Genomes or Metagenome: Our popular program provides $400 bacterial genomes and metagenomes data only.. this program gives roughly 2x150bp 10-20 million paired sequences per sample.. note the turnaround for these vary from a few weeks to a few months so do not put samples on this program that you are in a hurry to have sequenced ;-)
    ***Rapid bacterial Genomes starting $700 including assembly and annotation >40x coverage, $500 without assembly annotation 2x300bp 1-2 million sequences.

      ~2.5Gb/sample in this paper:


      This Illumina app note did 5-15Gb/sample:
      http://www.illumina.com/content/dam/...tagenomics.pdf

      This paper did 4Gb/sample:
      http://www.sciencedirect.com/science...31312815001626

      Human Microbiome Project:
      A BioProject is a collection of biological data related to a single initiative, originating from a single organization or from a consortium. A BioProject record provides users a single place to find links to the diverse data types generated for that project


      My intuition is that it varies pretty drastically depending on your environment, and you might end up resequencing if you don't hit saturation the first time around.

        Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
        by SEQadmin2



        Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

        Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

        New Genomics Technologies Take Aim at Long-Standing Limits
        by SEQadmin2


        Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

        We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
