Welcome to RadCamp 2019 - The New York City Edition

Part I - Wet lab (3RAD protocol)
September 14-15, 2019

Part II - Bioinformatics (ipyrad)
October 12-13, 2019

Schermerhorn Extension Building Room 1010
Columbia University
New York City


This two-part workshop is designed to guide participants through a full RADseq pilot study.

Part I of the workshop is an interactive 2-day wet-lab workshop where attendees will be guided through a RADseq DNA library preparation (3RAD). Participants will have the option of bringing 10-20 of their own extracted DNA samples that can be used in the workshop to develop pilot data for their research. In addition to demonstrating and generating 3RAD libraries, we will introduce RADseq methods, explain common pitfalls and focus on ways to increase data quality and reduce missing data while reducing costs compared to other protocols. At the end of the first weekend the libraries will be pooled and sent for paired-end Illumina sequencing to generate ~1M reads per sample. The best part is that the sequencing cost will be completely subsidized (free!). One month later we will meet again to analyze these data.

In Part II of this workshop, we will introduce RADseq assembly, phylogenetic and population genetic methods, high performance computing, basic unix command line and python programming, and jupyter notebooks to promote reproducible science. We will introduce ipyrad, a unified and self-contained RAD-seq assembly and analysis framework, which emphasizes simplicity, performance, and reproducibility. We will proceed through all the steps necessary to assemble the RAD-seq data generated in Part I of the workshop. We will introduce both the command line interface, as this is typically used in high performance computing settings, and the ipython/jupyter notebook API, which allows researchers to generate documented and easily reproducible workflows. Additionally, we will mentor participants in using the ipyrad.analysis API which provides a powerful, simple, and reproducible interface to several widely used methods for inferring phylogenetic relationships, population structure, and admixture. Participants can give a short research talk on October 12.

This workshop is intended as a bootcamp for early career students, post-docs, or faculty to learn best practices that they can then help to disseminate to the broader community. The opportunity to learn while generating and analyzing real data is a bonus that we hope will accelerate the learning process, particularly for early stage students who can use the pilot data for their thesis research. This was made possible through generous funding from the Society for the Study of Evolution, the Society of Systematic Biologists, Columbia University, and The City College of New York.

Organisers, Instructors, and Facilitators


Registration for each weekend will be separate and preference will be given to participants who can commit to attending both weekends. The workshop will be limited to ~30 participants per weekend. This workshop is geared toward practicing field biologists without RADseq data for their system and with little or no computational experience. We encourage all scientists to submit their application. We especially welcome women and under-represented minorities and early stage students, or early-career faculty with the potential to pass on skills to large groups. Note that you will be responsible for your own lodging, transportation, and meals. We will provide coffee and snacks during breaks. Please only apply to the workshop if you acknowledge that if accepted, you will commit logistically and economically to attend. A registration fee ($15 per weekend) will be due upon acceptance. Nobody will be turned away for lack of funding - if you would like to request a fee waiver, contact the organizers.
