    Looking for structural variants with paired-end sequencing data

    Hello community,

    I am dealing with 150bp, paired-end, Illumina sequencing data from a relatively small bacterial genome (around 2MB). I would like to identify structural variants, specifically small genomic inversions compared to the reference sequence.

    My reasoning here is that inversions should be recognizable with broken pairs of paired-end data, specifically those that are on the same orientation. Basically, paired-end mates are normally on both Forward and Reverse strand (FR), but if they align perfectly on the same strand (FF or RR) then I might be looking at genomic inversion in that part of the genome.

    My question: How do I pool out read pairs that map to the same strand?

    Thank you,
    TP

    OK - just in case someone else is looking for the same thing: simply use --ff option in bowtie when aligning paired-end reads.

      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.
