  • Identifying small RNA sequence within whole genome sequence

    Hi all,

    I want to know if there are any useful bioinformatic tool to find small RNA sequence within a whole bacteria genome.

    Thank you in advance,

    Inma

    Hi,
    You can use Rfam for predicting the ncRNAs and also check SIPHT.

      Hi Krish,

      Thank you for your answer. Can I predict small RNA within whole genome using Rfam and SIPHT?
      My genome have been sequencing recently, and the functional annotation is not available in any database. Maybe I could search for similar organisms in Pfam, download their small RNA and perform BLAST agaisnt my genome in order to find some of them by similarity. Do you mean that?

      Thanks :-)

        Hi,

        For Identifying ncRNAs,
        1) Download directly Rfam database from Rfam.
        2) Download Infernal and install it.
        using rfam perl script or cmsearch you can find ..

        For sRNAs
        Use reference

        perform blast and find out it in our genome..

        If your interested to use online.. (RNAspace)
        * Check with ur genome assembly or use reference and do blast.

        For functional annotaion you can use RAST.

          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...
