    getting .nal files from blast

    Hello,

    So I am making my own databases from fasta files using Blast version ncbi-blast-2.5.0+.dmg and getting an error that is linking back to by database creation by not having a .nal file created.
    I am entering in:
    makeblastdb -in test2.fasta -out MV1SDB_a/MV1SDB_a -parse_seqids -dbtype nucl

    And getting the following files outputs:
    MV1SDB_a.nhr
    MV1SDB_a.nin
    MV1SDB_a.nog
    MV1SDB_a.nsd
    MV1SDB_a.nsi
    MV1SDB_a.nsq

    How do I change my coding to recieve a .nal file as one of my outputs.

    This is a near duplicate of your other thread where you have been given advice and help: http://seqanswers.com/forums/showthread.php?t=72083

    The .nal file is a plain text file describing how to treat a set of BLAST nucleotide database "chunks" as a single database. When making a database from a single FASTA file this won't happen (unless your FASTA file has an enormous number of sequences).

      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.
