The most viewed preprints in July 2013 were:

• Our Paper: Genome-wide inference of ancestral recombination graphs. Adam Siepel gives a nice overview of ancestral recombination graphs, and discusses his preprint with Matthew Rasmussen on a new method for inferring them.
• Our paper: Assemblathon 2 and pizza. The Assemblathon 2 paper was officially published this month. In this popular post from January, Keith Bradnam describes why assembling a genome is like making a pizza.
• Genetics of single-cell protein abundance variation in large yeast populations. Albert et al. develop a new method for mapping genetic loci that influence protein levels in yeast, and identify a number of hotspots that control levels of multiple proteins.
• Evolution on genotype networks leads to phenotypic entrapment. Manrubia and Cuesta argue that the structure of genetic networks plays a role in evolutionary dynamics.
• Cloudbreak: Accurate and Scalable Genomic Structural Variation Detection in the Cloud with MapReduce. Whelan et al. develop a computational tool for efficient and large-scale detection of structural variants.
