Virtual Workshop October 2016

Conference Calls

Virtual office hours will be held on Monday and Wednesday, October 24th and 26th, 10:30-12am and 2-3pm (US PDT). Please carefully read the instructions on the cover page of the booking sheet. If you have questions or concerns, please email James (james.dunne@stanford.edu)

Webinar

The OpenSim team will deliver a live Welcome and Closing Webinar on Monday, October 24th and Friday October 28th, respectively. The Webinars will feature short talks followed by questions from the audience about Workshop and presentations from workshop award winners (closing Webinar). The Webinar recording for the Closing Webinar can be found here.

Google Slides (Project Goals and accomplishments)

The Goal slides are an Online Poster presentation where you get to show off your work, ask questions, and provide support to your Workshop colleagues. Carefully read and follow the instructions and examples presented on slide 1-3. We’ll also give out prizes based on the discussion about the projects. You must complete your workshop goals slide by Monday, October 24th at 9am (US PDT), and drop in throughout the day to join the discussion. 

Awards Voting 

The awards include Biggest Research Discovery, Technical Grand Prize, Coolest Demo or Video, and Best Blooper. Award winners will be invited to present their slides and talk about their workshop experience during the closing webinar.

Question and Answer Forum

Follow the links to find simple guides for asking good questions and providing helpful answers. During the workshop, the OpenSim team will devote part of each day to answering questions, but we hope that participants will be active in answering each other's questions, as well. The workshop is about sharing experience and building community. Remember that it is better to ask a greater number of smaller, tractable questions than a single, large post with multiple questions. Try to be specific. Use tags liberally, upvote answers that you find very helpful, and contribute your experience. Be positive and have fun!

Should I use latest code from Github or stay with version 3.3?

The latest, cutting edge, code-base for OpenSim API now lives on Github (aka 4.0). Many participants expressed interest in migrating to version 4.0. Migration has benefits but also comes with several caveats:
1. Version 4.0 introduces new abstractions that make it easier to create your own "Components" (e.g. Controllers or Muscles) and to extract/report results with little code but to use these you need to learn a new set of abstractions and API calls. The documentation is still limited and we have not finished testing the code.
2. The API will keep changing, so you will likely need to make some updates to any code after the official 4.0 is released.
3. There's currently no GUI built on top of version 4.0 (not for a few months). Keep that in mind if you need GUI functionality (e.g. to visualize your model or results). Model and storage file formats have changed and so are not supported by the 3.3 GUI
