Peering Through the Flowcell Glass, Darkly

As 2013 draws to a close, I've decided to stick my neck out and make some predictions for 2014.  Perhaps I'll get lucky and a few will even come true!  After several mental experimentations on the structure, I'll settle for stepping roughly past each major player.

Assembly Could Benefit From More Circular Reasoning

It was very gratifying to get comments on my recent piece on a de novo assembly review from both a referee of the manuscript (the amazing Heng Li) as well as one of the authors of the piece (though I am truly feeling guilty I forgot to reach out to the authors).  Of course I was having my usual post-post regrets of things not written, such as the whole interesting topic of dealing with (and leveraging) uneven coverage in metagenomes and when assembling from amplified samples.  But one other thing I was reminded of is one of the minor complaints I have with assembly programs: a lack of proper handing of circular genomes.

Assembling a Review of a Review of Assembling

A review on short-read de novo genome assembly appeared recently in PLoS Computational Biology, titled "Next-Generation Sequence Assembly: Four Stages of Data Processing and Computational Challenges".  I think the review has a number of merits, but I also find a number of frustrating flaws.  I'm going to write this entry much as I would have written a referee report on it.  Unfortunately, that will mean I'll dwell a bit more on the flaws than the assets, but if you are interested in the field
