HybSeq Pipeline

Targeted bait capture (HybSeq) is a technique for sequencing many loci simultaneously based on bait sequences. Once the sequence data is generated, usually by Illumina, the next task is to sort the reads based on the target loci and assemble them. I generated this pipeline to work with data we…

Structure Pipeline

Users of Structure (Pritchard et al, 2000) may be familiar with the interface of the BioHPC cluster at Cornell. Unfortunately, guest access was discontinued in May, 2011. If you have structure installed on your SGE supercomuting cluster, several features of the web-based BioHPC cluster interface can be replaced with a…

Mating Systems in Sphagnum

Sphagnum capillifolium expressing male

Synopsis: This research is the first to characterize the diversity of mating patterns in natural populations of Sphagnum. In peat mosses, sexual condition is a species-level trait: most species produce only one type of gamete (unisexual) while a minority of species are bisexual, producing both egg and sperm in the…
