I was a reviewer of the PLoS One paper, An Integrated Pipeline for de Novo Assembly of Microbial Genomes, and just recently came across the review again. I didn't post it at the time, but heck, why not now? ;)
The authors describe a new assembly pipeline, A5, that integrates a variety of common steps into a single straightforward software package. The description of the pipeline is quite good and the steps included seem well thought out and justified. Overall it is a well-written paper that discusses what appears to be a useful pipeline.
It is especially nice to see an assembly pipeline that is completely integrated (error trimming, correction, etc.) and has a simple and sensible input file format. The separate contigging and scaffolding stages are also welcome.
The Nextera compatibility is an excellent technical point and it's great that this is included in the software (although I have no idea how widely used this protocol is).
A general reservation is that (to paraphrase an excellent point made in the paper) "A common approach employed by the hapless bioinformatician involves downloading many different assembly packages and evaluating the results until a perceived optimum has been achieved." I feel like the last thing we need is a new assembly pipeline, since we really don't have a good sense for how well the existing ones work...
