SciWorks Discovery Data Acquisition & Analysis Software

SciWorks^® Discovery Pro Data Acquisition And Analysis System

While SciWorks Discovery is the ideal data acquisition and analysis system for most electrophysiology experimental protocols, upgrading to Sciworks Discovery Pro enables the scientist to use the tools of Sciworks for more channels of data, to generate more complicated stimulation sequences and waveforms, and to incorporate video acquisition and analysis.

Upgrading to SciWorks Discovery Pro is also cost effective. While you can pay a price difference later to upgrade from the Discovery to the Discovery Pro software package, it is necessary to purchase the required a/d hardware that supports Discovery Pro at full price. Thus, purchasing Discovery Pro upfront means not double paying for acquisition hardware systems.

SciWorks Discovery and Discovery Pro can be configured to run any of the following experiments, and countless others.

The following list contains only a few examples of the variety of experiments SciWorks Discovery can perform and analyze.

Click on the section headings for details and videos regarding how SciWorks can be used in your lab to measure average responses, measure population spike amplitudes, perform Fourier analysis to obtain a power spectrum, interval measurements, detect seizures, and perform many other protocols. Adding VideoBench to either Discovery Pro bundle enables video collection and analysis functionality.

Data Acquisition

An experiment is defined using the built-in tools of SciWorks Discovery or Discovery Pro. These tools are oriented around common experiment tasks, such as data acquisition, stimulus generation and delivery, data display, data analysis, annotation of data, timing, and external device control.

Data Acquisition (Analog and Digital Input)

• Discovery Pro 64: Acquire from 1 to 64 channels of continuous single ended ("no gap") or discrete ("sweep" mode) data (up to 128 with additional units).
• Discovery Pro 16: Acquire from 1 to 16 channels of continuous single ended ("no gap") or discrete ("sweep" mode) data
• Discovery 8: Acquire from 1 to 8 channels of continuous single ended ("no gap") or discrete ("sweep" mode) data
• Independent sampling rate and A/D gain settings per channel (Discovery Pro bundles only)
• Record both acquired and analyzed data to disk for off-line processing
• All data items are timestamped to 1 microsecond resolution for experiments lasting hours, days, weeks with a high-resolution clock

Stimulus Generation and Analog/Digital Output

• Generate stimuli and acquire data at the same time
• A stimulus "List Generator" automates stimulus output and provides both random, pseudo-random and fixed output
• Generate analog waveform output for auditory or behavioral queuing. (* Discovery Pro only)
• Play and manipulate .wav files for auditory stimulation (* Discovery Pro only)
• Programmable counter/timers interface for complex pulses or pulse trains

Experimental Control, Execution and Timing

• Dynamically change experiment parameters while the experiment is executing
• Conditional experiment execution based on experimental results and external equipment
• Timers, counters and looping controls for automated experimentation
• Read/Write to multiple digital ports for experiment control
• Customizable windows for displaying both acquired and analyzed data in real-time
• Extensive updating capabilities of stimulus, counter, digital I/O in trial markers, with simultaneous recording of data
• External triggering of data acquisition using TTL triggering or Digital I/O

Experimental Design and User Interaction

• Complex experimental protocol can be easily created using a combination of events and objects with common defaults and intuitive settings
• Design your own menus and dialogs to use during real-time and file playback
• Design status warnings when settings are incomplete or incorrect even before execution
• Real-time logging of experiment protocols and execution

Data Analysis

SciWorks Discovery or Discovery Pro software enables real-time data-analysis while not interrupting data acquisition.

Spike records can be sorted using the AutoSort module, or sorted by a user driven analysis process. Separated spikes can then be catalogued and quantified for use in rasters, histograms, rate calculations, etc.

EEG records can undergo Fourier analysis online.

Population spikes can be measured.

And all of the analyzed data can be stored at the same time as the raw recordings.

Find something interesting in a review of the analyzed data, but need to go back to the original for a re-analysis? No problem. You can call up the entire record, and start anew. Or, you can instantly jump to a particular time stamp, or experiment marker, without having to load in the entire record.

Data Analysis

• All Analysis can be performed while data is being acquired or from file playback
• Detect and extract events based on software window discriminators
• Real-time Multi-Unit Spike Sorting & Separation
• Extract key waveform parameters such as peak, valley, area, dV/dt, and many others
• Waveform averaging
• Event or spike triggered averaging
• Digital filtering
• Detect waveform bursts
• Detect spike/event bursts
• Rate meters and rate gauges
• Firing rate grids
• Perievent time (PETH), Inter-event interval (IEIH) histograms and Dot Rasters
• Cross Correlation Histograms
• Continuous Event interval analysis
• Signal conditioning such as auto-baseline and waveform smoothing
• Statistical calculations for waveform and single value data
• Fourier Analysis including various power calculations
• Sonograms and spectrograms
• Statistical distribution analysis and display
• Acquire to a real time spreadsheet for custom analysis and reporting
• Analysis for custom multi-array and multi-channel electrode analysis for tetrodes, stereotrodes and multi-array electrodes
• Perform math operations defined by custom equations to operate on single value or array data (i.e. histograms or waveforms)
• Curve fitting of single values

File Output and Data Replay

• Write to or read from one or more files simultaneously during experimentation
• High performance file format allows for multiple data types (including raw, analyzed and markers) to be saved to the same file
• Multiple formats supported for both import and export (i.e. DDF, WorkBench, Discovery, ABF, CED, Neuralynx, Plexon, EDF, NEV, Neuroshare, and ASCII)
• Data can be replayed from file just as it was acquired using slower, actual, or faster timing
• Drag & Drop, Copy & Paste complete files or selected data for replay and analysis
