  • Viral genome assembly from RNA-seq data

    Hi,

    I'm performing a RNA-seq analysis from a virus infected plant. After mapping the Illumina Hiseq paired reads against the plant genome, I used the unmapped reads to blast the virus genome available. Once I separated virus reads from other unmapped reads I would like to assembly the virus genome. Which is the best way to do it? I used before velvet and trinity for eukaryote transcriptome assemblies but I'm not sure if I can use the same software or approach for virus.

    I would appreciate someone could guide me.

    Thanks a lot

    Dear,

    generally i used bowtie first then samtools to generate mapped reads and then use Macvector software to assemble the genome.

    thanks.

      This is a very naive question, but how can you be sure that the unmapped reads belong to a virus?

      Isn't it just as likely that they belong to unmapped regions of the plant transcriptome, sequencing errors, ...?

        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...
