    Download nucleotide sequences database

    Hello,

    I want to build a BLAST tool to compare DNA seq with DNA database ex: GenBank.

    And I want to store the DNA sequences database, comparison results, and other tables in SQL database.

    Nucleotide sequences databases provided by NCBI is not created using tables, they are set of binary files so, I cannot store them in a relational database.

    Is there is another place that provide the sequences database as a set of tables?

    Hope you getting my point.

    Best regards,
    Alaa

    I think Ensembl does, but I'm not sure.

      Might be a bit big for a relational database ! We're talking terabytes of sequence information at the least for most useful databases.

        Nine Things a Sample Prep Scientist Thinks About Before Sequencing
        by SEQadmin2


        I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

        Here are nine questions we think about, in roughly the order they matter, before...

        From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
        by SEQadmin2


        Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


        The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
