    Mapping reads to de novo transcriptome

    Hi Guys and Gals,

    I am trying to analyze some RNA-seq data from a species without a Genome and all that jive. A assembled putative transcritptomes with Velvelt, Trans-Abyss, and Trinity and used CAP3 and CD hit to link assemble those to an EST collection. I used that CLC Genomics Workbench to map the sequences, but I do not want to depend on proprietary software for anything is this life (it is enough that I need to use MS Word). So is Bowtie still the best solution (as the manual says it will work with fragmented reference)? Can you use TopHat in the absence of a splice junction library and would that be worth it (given that as far as I understand, that would be basically bowtie)? Lastly, last say I have a very poorly assembled genome draft, is that better than the de-novo transcriptome?

    Thank you!

    Tiago

    Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.

    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...
