RTXI, the Real-Time eXperiment Interface, is a hard real-time data acquisition and controls application for use in a biological research. At the core of RTXI is a Real-Time Operating System (RTOS), which uses the Linux kernel to provide deterministic control in a variety of experimental settings. It is fast, free, and open-source. Our system is currently used in labs all over to world to probe diverse, technologically challenging problems, such as dynamic probing of ion-channel function, control of cardiac arrhythmia dynamics, and control of deep-brain stimulation patterns.
Experimentalists' ability to perturb biological systems has traditionally been limited to rigid pre-programmed protocols or more flexible, albeit reflex constrained, operator-controlled protocols. In contrast, real-time control allows dynamic probing of biological systems by parameter perturbations calculated from instantaneous system measurements. With it, researchers can address diverse unanswered questions that are not amenable to traditional approaches.
Unfortunately, real-time control is not possible with standard operating systems and software. Furthermore, commercial real-time systems are costly and often designed for industrial applications, and the proprietary software licenses and drivers that come with them only exacerbate the issue. To get away from that, we developed RTXI. It's fast, free, and flexible, and it's compatible with a wide range of experimentation hardware.

We now have a new website. It’s not quite feature-rich yet, but it’s a nice, fresh site to coincide with the long-planned release of RTXI 2.0. Look here in the future for all documentation, tutorials, videos, etc. related to using RTXI and closed-loop, real-time electrophysiology in general. ...
