  • Annotating a contig and bacterial or eukaryotic (contamination screening)?

    Hi all,

    We are sequencing the genome of a microscopic invertebrate. Our assembly has significant bacterial contamination that we would like to remove prior to gene modelling. Is anyone aware of a publicly available tool that includes diverse bacterial genomes as references that I could use to annotate my contigs as either bacterial or eukaryotic?

    Thanks!

    BBSplit was designed for separating reads into pools so you can enrich reads of potential interest (http://seqanswers.com/forums/showthread.php?t=41288). Only problem in your case is you don't know which bacterial species you should be screening against. If you have a rough idea you could select a representative set of genomes and start there.

    If a close(r) relative of the microscopic invertebrate has had its genome sequenced then you could use that as the "bait" to fish out reads that would represent things of interest to you.

      Thanks! This was not on my radar but should be very helpful!

      Best,

        Best Practices for Single-Cell Sequencing Analysis
        by seqadmin



        While isolating and preparing single cells for sequencing was historically the bottleneck, recent technological advancements have shifted the challenge to data analysis. This highlights the rapidly evolving nature of single-cell sequencing. The inherent complexity of single-cell analysis has intensified with the surge in data volume and the incorporation of diverse and more complex datasets. This article explores the challenges in analysis, examines common pitfalls, offers...
