    Velvet questions

    I just installed Velvet for assembling, but have some questions to ask.

    1. Should I use data after alignment or not? Why fastq file without alignment is accepted by velveth?

    2. How to run sequence assembling against a reference genome with Velvet? The Velvet manual is too simple and confusing.

    Thanks a lot,

    after what alignment???

    velveth does not use quality values of fastq files but velvet just does not care if you give the reads in fastq or fasta format.

    velvet does not support an assembly with a reference genome! for that you need the extension columbus: http://www.ebi.ac.uk/~zerbino/velvet/

    how can the velvet be too simple and also too confusing. Just give it a try you will see it's quite easy. ;-)

      I thought Velvet is for assembling with a reference genome. This is why I was confused.

        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
