The Meshing with Data Hackathon is June 29 – July 1, 2018 in Engine 4, Bayamón, Puerto Rico. IDI-BD2K co-sponsored the event, which seeks to develop innovative solutions to help address public health and safety issues during and after a catastrophic event such as the 2017 hurricanes in Puerto Rico.

Our Healthcare Innovation Replicathon and Data Carpentry Instructor Training events were a success! Students and faculty from many campuses and departments met on March 24-25, 2017 at the Engine-4 co-working space in Bayamón. Puerto Rico.. Students took part in the 36-hour Healthcare Innovation Replicathon, led by Alejandro Reyes and Keegan Korthauer from Rafael Irizarry’s rafalab (Dana Farber Cancer Center & Harvard) Patricia Ordoñez (UPR RP Computer Science), and Phillip Brooks from Titus Brown’s Lab for Data Intensive Biology (UC Davis). Students took brief tutorials on R, reproducible research, and statistical analysis, then dove in to examine two studies on pharmacogenomics in cancer cell lines.

Interdisciplinary (and inter-campus) teams of students worked for 24 hours on a re-analysis of data from two large scale studies looking at the effects of 15 drugs in 240 cancer cell lines. They presented their findings on Saturday, including errors in the published figures, their recommendations on improved measures of drug effects, and lists of drugs for follow-up studies.
The Healthcare Innovation Replicathon wasn’t just about data, statistics, programs and cancer. Students, mentors, sponsors, and faculty got a chance to interact in a welcoming environment, with good food, top-notch Internet, and even a guitar or two.

Meanwhile, faculty from Interamerican University Bayamon Campus, UPR Humacao, Mayaguez, Rio Piedras and private industry went through Data Carpentry Instructor Training led by Rayna Harris (UT Austin), Sue McClatchy (The Jackson Laboratory), and Tracy Teal (Data Carpentry). Data Carpentry Instructor Training presents instructors with research-based best practices for teaching data science to novices. Stay tuned for announcements of new Data Carpentry workshops with some of the new instructors soon.

Un replicathon, similar a un hackathon, se caracteriza por ser una actividad de 36 horas continuas de trabajo analítico y de programación para crear soluciones reales usando la tecnología. A diferencia de un hackathon tradicional, los equipos recibirán el mismo reto o problema: dos manuscritos científicos que llegaron a dos resultados diferentes utilizando los mismos datos. El fin es que el equipo de participantes interprete los datos y presente sus conclusiones. En un hackathon, normalmente la solución se realiza en forma de un App (una aplicación móvil o web). El replicathon requiere colaboración interdisciplinaria entre los expertos en programación, los de análisis de datos, los del contexto (genómica en este caso).
Estudiantes pueden matricularse para participar aqui:
Rafael Irizarry, IDI-BD2K partner, has submitted this problem for the Heathcare Innovation Replicathon.
In 2012, two studies (Garnett et al and Barretina et al) attempted to correlate large numbers of gene expression, mutation, and copy number measurements in hundreds of cancer cell lines with sensitivities to hundreds of different drugs, with the goal of finding genes or mutations that might indicate certain kinds of cancers with vulnerabilities to specific drugs. However, a subsequent study (Haibe-Kains et al 2013), attempting to replicate the initial findings, found major inconsistencies in the results of the two studies. We can review the papers, download the data and analyze it ourselves to form our own conclusions.

The registration for the Varmed Management Group and IDI-BD2K Healthcare Innovation Replicathon is open. Join us March 24-25, 2017 for this event. Mentors from the University of Puerto Rico, Harvard, University of California Davis, Massachusetts Institute of Technology and more will guide groups of students to examine the issues of replicability in a set of experiments asking the same question and obtaining different answers.
