OpenEx is a powerful experimentation platform that provides researchers with flexibility and configurability found in no other commercial system. The OpenEx Software Suite is the core group of programs for configuration, control, display and analysis; brought together under a seamless project interface. Built on a distributed client/server architecture, all OpenEx applications can run in parallel. This allows you to configure any number of custom client windows for your specific application, each able to access data as it’s acquired and stored.

TTank is a data server that operates behind the scenes to provide fast, reliable data storage and retrieval. Store and provide data to many applications in real-time during an experiment or offline for post-hoc analysis of data.
Response waveforms as well as behavioral and stimulus events can be time stamped with microsecond accuracy and stored to our unique DataTank format. This format allows TTank to save large amounts of data and efficiently serve data up to client applications for real-time display and analysis.
OpenWorkbench is the interface between OpenEx applications and the System 3 hardware. By working directly in OpenWorkbench the user can provide instructions about the experimental protocol to the hardware. Through OpenWorkbench’s graphical user interface, you can select devices for your experiment, specify which functions each will perform, select which data to store, preview recorded data in real-time and control the general flow of the experiment.
Parameters such as filter settings, single-unit thresholds and stimulus variables, can all be modified on the fly. You can combine built-in components to create your own visual interfaces for parameter control and data display. OpenController includes over twenty customizable controls including gauges, switches, sliders, manual and automated spike sorting controls and data displays.
OpenScope was developed to visualize neural spike data and other bioelectric waveforms (e.g. EEGs or local field potentials) in real-time and offline. The TTank data server sorts and serves data to the OpenScope plots, which are updated as each of the selected data tank elements become available. Dynamically display stored data during the course of the experiment or replay the entire experiment later, showing data as it was acquired. A number of plot types allow viewing of raw data in several ways including: continuous time base, spike shape overlay, PSTH and raster plots.
OpenBrowser accesses data through the TTank data server. Data from one or more data tanks can be selected, filtered, previewed and exported. OpenBrowser supports Neuroshare and a variety of export formats including a standard ASCII file and formats for NeuroExplorer® or Plexon’s Offline Sorter.
OpenProject acts as the essential environment integration tool, greatly simplifying the system’s ease of use. With OpenProject, all OpenEx programs are brought under the control of a single management tool and all of the files related to a given experiment are managed automatically under a single directory structure.
