  • makeblastdb is making multiple sets of files, how can I fix it?

    Hello!

    I just realized I should have posted this to this forum, so here it is again, sorry!

    I am a graduate student at UC Berkeley currently working with raw reads of several transcriptomes in an attempt to find and assemble reads that match a couple of genes I'm studying. This site has already been very useful to me (Thank you!!!!), but I haven't found any answers pertaining to my current problem.

    I was hoping I could get some help with a BLAST problem I'm having. I am working with standalone blast, and am building blast databases from fasta files of transcriptome raw reads. I have successfully used the command:

    makeblastdb -in COST_1_final.fasta -input_type fasta -dbtype nucl -out COST_1_final for several fasta files of raw reads (with varying names of course) but a few of the files result in multiple sets of database files, marked for example <filename>.00.nhr and <filename>.01.nhr with what I believe is an alias file <filename>.nal

    The command as it runs give the usual message:
    Building a new DB, current time: 10/15/2015 10:49:55
    New DB name: COST_u_final
    New DB title: COST_u_final.fasta
    Sequence type: Nucleotide
    Keep Linkouts: T
    Keep MBits: T
    Maximum file size: 1000000000B
    Adding sequences from FASTA; added 16313457 sequences in 937.429 seconds.

    but then results in multiple sets of files.

    Any ideas about how I can make just one set of database files, as has successfully happened with the rest of my fasta files? I would really appreciate any help!!

      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...
