RTXI 2015 Conference

Thanks to all who came out to the conference in Atlanta. It was wonderful to see what our current users have been doing and also meet some potential new ones. Moving forward, we'd like to expand RTXI in terms of both function and usage. When the next conference comes around, we want to see even more people there!

RTXI 2015 is a small meeting to discuss ongoing efforts in applying real-time methods to experiments in biology and physiology. While this conference is targeting and highlighting users of our RTXI software (http://www.rtxi.org), all are welcome! This meeting builds upon the success of two meetings we hosted approximately a decade ago in Atlanta (GT Real 2005) and Boston (BU Real 2006).

Much has changed in ten years, both in terms of hardware and the increasing number of experimental techniques using real-time methods. This conference features a single track session for two days, along with workshops. Ample time in structured and open sessions will give us all a chance to share ideas, software, and technical knowledge.

The Real-time Experiment Interface (RTXI) is an open source software platform for hard real-time data acquisition and closed-loop experimental control in biological experiments. Its power and flexibility have enabled users over the years to implement complex protocols in a variety of experiment types. Currently, RTXI is used to provide real-time, closed-loop control of single cell, cell network, animal, and human electrophysiology studies.

RTXI 2015's topics will focus on recent applications of RTXI. If you'd like a sense of what RTXI has done for experimentalists over the past 15 years, look through our list of publications.


Dynamic clamp and similar methods
Cardiac control
Closed-loop neural stimulation
Applications to neurological disease (Parkinson's, epilepsy, etc.)
Open-source software development

We will have time dedicated for attendees who want to host talks about their own uses for RTXI. You can specify whether you'd like to present anything when you register. Once the details of this event are finalized, look here for session details and a schedule.

Our current RTXI developers will hold workshops to help new users get started using it and demonstrate v2.0 to current ones. Emphasis will be given to benchmarking RTXI and real-time performance, troubleshooting, and module development.

1530-1600Workshop Part 1: Architecture of RTXI
We will go over the hardware (processors, DAQs, graphics cards) and software (threading architecture, RT and non-RT threads) components of RTXI and then explain how they provide hard real-time performance. We will show the basic code structure and explain how to run real-time code within the RTXI framework. This section will also include a brief demonstration of each system module (e.g. the oscilloscope, data recorder, etc.) within the context of RTXI's software architecture diagram.

1600-1625Workshop Part 2: RTXI Live Demos (and Coffee Break)
We will setup stations running RTXI for everyone to try out while getting coffee. RTXI users at each station will help explain what the workspace is doing and how it's working. This will be a pre-defined set of workspaces that we walk through setting up and testing, with the purpose of familiarizing attendees with the interface. Stations will be left running for people to use during the reception.

1625-1700Workshop Part 3: Profiling and Troubleshooting RT performance
This session will focus on how each workspace set up could fail and considerations for dealing with problems in each. Special attention will be given to hardware matters (graphics cards, DAQs), proper driver and kernel configurations, and benchmarking real-time performance with our built-in tests. Mention will also be given to all the new resources we have put into place, such as GitHub, our website, numerous modules, and our contact information so we can help or even make arrangements for us to come to you and get you set up.
