Department of Computational Medicine and Bioinformatics, University of Michigan

Abstract: I-TASSER (Iterative Threading ASSembly Refinement) is a composite method for atomic-level protein structure prediction and structure-based protein function annotation. The on-line server system has been widely used by the biomedical community with registered users coming from more than 130 countries. In Fall 2016, I-TASSER began using XSEDE’s Comet supercomputer; as a result, I-TASSER singlehandedly tripled Comet’s users by adding more than 8,000 unique users in the first several months of integrating with Comet. In this presentation, we will discuss the following: (1) How I-TASSER generates protein structure and function predictions; (2) how I-TASSER is integrated with the XSEDE Gateway system and how the XSEDE resources have enhanced the functionality of I-TASSER and its usefulness to the community; (3) How to use the I-TASSER Gateway and how to interpret the I-TASSER output results for normal users; and (4) how to improve the quality of the I-TASSER model for advanced users (e.g. introduction of restraints, and strategy for modeling multi-domain proteins etc). The I-TASSER gateway is available at http://zhanglab.ccmb.med.umich.edu/I-TASSER/.

Chem Compute Science Gateway:  Computational Chemistry for Undergraduates
Presented by Mark Perri, Assistant Professor of Chemistry, Sonoma State University

Abstract: We report on our efforts to provide a free, easy to use, but powerful interface for undergraduate students to submit computational jobs.  Computational experiments are critical for engaging students in Physical Chemistry because they provide the opportunity for visualization of concepts, such as molecular orbitals.  The Chem Compute Science Gateway allows students to submit jobs to the NSF XSEDE supercomputer network.  Students can submit jobs using the GAMESS (General Atomic and Molecular Electronic Structure System) ab initio quantum chemistry package and the TINKER Molecular Modeling Package (Molecular Dynamics).

Webinar: Jupyter as a Gateway for Scientific Collaboration and Education

July 20, 2017

Jupyter as a Gateway for Scientific Collaboration and Education
Presented by Carol Willing, Cal Poly SLO and Jupyter Steering Council

Project Jupyter, evolved from the IPython environment, provides a platform for interactive computing that is widely used today in research, education, journalism and industry. The core premise of the Jupyter architecture is to design tools around the experience of interactive computing, building an environment, protocol, file format and libraries optimized for the computational process when there is a human in the loop, in a live iteration with ideas and data assisted by the computer.

The Jupyter Notebook, a system that allows users to compose rich documents that combine narrative text and mathematics together with live code and the output of computations in any format compatible with a web browser (plots, animations, audio, video, etc.), provides a foundation for scientific collaboration. The next generation of the Jupyter web interface, JupyterLab, will combine in a single user interface not only the notebook, but multiple other tools to access Jupyter services and remote computational resources and data.  A flexible and responsive UI allows the user to mix Notebooks, terminals, text editors, graphical consoles and more, presenting in a single, unified environment the tools needed to work with a remote environment.  Furthermore, the entire design is extensible and based on plugins that interoperate via open APIs, making it possible to design new plugins tailored to specific types of data or user needs.

JupyterHub enables Jupyter Notebook and JupyterLab to be used by groups of users for research collaboration and education. We believe JupyterHub provides a foundation on which to build modern scientific gateways that support a wide range of user scenarios, from interactive data exploration in high-level languages like Python, Julia or R, to the education of researchers and students whose work relies on traditional HPC resources.

VectorBase: A bioinformatics resource for invertebrate vectors and other organisms related with human diseases 
Presented by Gloria I. Giraldo-Calderón, PhD, VectorBase Scientific Liaison/Outreach Manager 
Contact: ggiraldo at nd dot edu

Abstract: VectorBase (www.vectorbase.org) is a free, web-based bioinformatics resource center (BRC) for invertebrate vectors of human pathogens, funded by NIAID/NIH. This database is the ‘home’ of 40 genomes of arthropod vectors and pests and also has transcriptomes, proteomes and population data for an even wider list of species. The population biology data includes lab and field collected information and, in addition to the data imported from external databases or directly submitted by users, VectorBase also generates and computes primary data. Over its 13 years of existence, the discovery and interpretation of hosted data has been used for basic and translational research, as expressed in numerous scientific publications, using data from one or more studies in new or re-purpose analyses, descriptions, and hypotheses testing. Raw and process data can be exported or downloaded in a variety of different formats, visualized, browsed, queried and analyzed with the site tools or any other external tools. VectorBase data, tools, and resources are updated every two months. The website has extensive documentation resources for new and experienced users including tutorials, video tutorials, practice exercises, answer keys, and sample files.

CitSci.org: A platform for engaging citizen scientists through individualized websites 
Presented by Greg Newman, Director CitSci.org & Research Scientist, Natural Resource Ecology Laboratory, Colorado State University 
Contact: Gregory.Newman at colostate dot edu

Abstract: Citizen science empowers individuals to pursue their interests in the scientific world. Members of CitSci.org are encouraged to investigate their own scientific questions or jump on board as a volunteer for an existing project. In parallel, citizen science programs create their own online projects where trained volunteers and scientists together answer local, regional, and global questions, inform natural resource decisions, advance scientific understanding, and improve environmental education. The platform provides tools to empower the citizen science gateway creators and their participants to ask questions, select methods, submit data, analyze data, and share results. CitSci.org provides tools for the entire research process and full spectrum of citizen science program needs: creating new projects, managing project members, building custom data sheets, analyzing collected data, and gathering participant feedback. To date, our volunteer coordinators have started 414 projects that have contributed a total of 697,984 measurements for analysis to answer local, regional and/or global questions.

Webinar: Data and Software Carpentry: Using Training to Build a Worldwide Research Community

May 10, 2017

Data and Software Carpentry: Using Training to Build a Worldwide Research Community
Presented by Tracy Teal, co-founder and the Executive Director of Data Carpentry, and Adjunct Assistant Professor with BEACON, Michigan State University

Although petabytes of data are now available, most scientific disciplines are failing to translate this sea of data into scientific advances. The missing step between data collection and research progress is a lack of training for scientists in crucial skills for effectively and reproducibly managing and analyzing large amounts of data. Already faced with a deluge of data, researchers themselves are demanding this training. Short, intensive, hands-on Software and Data Carpentry workshops give researchers the opportunity to engage in deliberate practice as they learn these skills. This model has been shown to be effective, with the vast majority (more than 90%), of learners saying that participating in the workshop was worth their time and led to improvements in their data management and data analysis skills. Data Carpentry events have trained over 20,000 learners since 2014 on 6 continents with over 800 volunteer instructors. The strategies of growing this community could be applied toward growing communities of gateway users, particularly by offering training and demonstrating the value of the skills and tools that will enhance their work.
