Summary

The industry leader in multi-channel data acquisition and analysis systems, DataWave Technologies® SciWorks® Experimenter software suite, combined with their advanced A/D hardware options, is the perfect compliment to A-M System’s Model 3500 and Model 3600 16-Channel Amplifiers.
SciWorks® Experimenter is a real-time data acquisition, analysis, and instrument control application designed for a wide variety of electrophysiology experiments, including:

  • Single Unit Recording
  • Multi-Unit Recording
  • Evoked Responses
  • Field Potentials
  • EEG
  • ECG / EKG
  • ERG
  • EMG

SciWorks® Experimenter provides the user with a single interface to control instrumentation, perform real-time data analysis, including multi-unit spike sorting and separation, generate complicated stimulation patterns, and write data to a multiple of common industry defined data formats.

Data Acquisition and Data Analysis processes are seamlessly integrated into a single software package. Users can define how the experiment should be run, collect data, run complicated anaylsis tools, and store raw and analyzed data all at the same time, without having to change software packages.

Current Recommended System Requirements are:

  • Windows XP, 7 or 8, 32 or 64 bit for real-time using USB data acquisition
  • CD-ROM
  • 35 Mb free disk space for installation
  • Additional free disk space for data files (experiment dependent)
  • USB 2.0 Port for USB data acquisition devices
  • CPU speed and memory requirements can vary depending on the type of experimentation

Data Acquisition

SciWorks® Experimenter software suite is an integrated software package, combined with their advanced A/D hardware, that enables users to design and perform sophisticated neurophysiological experiments, as well as record and analyze all data online during acquisition.
This page will focus on the Data Acquisition features of the SciWorks® Experimenter program suite.

An experiment is defined using Experimenter and its assorted built-in tools. 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.

Sciworks can be used to perform any of the following experiments:

  • Single Unit Recording
  • Multi-Unit Recording
  • Evoked Responses
  • Field Potentials
  • EEG
  • ECG / EKG
  • ERG
  • EMG

SciWorks® Experimenter provides the user with a single interface to:

  • control instrumentation
  • define acquisition parameters such as sampling rates and gain factors
  • perform real-time data analysis, including multi-unit spike sorting and separation, that can trigger other experimental contingencies
  • generate complicated stimulation patterns
  • annotate data files with messages, trial information, and timing flags
  • write data to a multiple of common industry defined data formats

Data Acquisition is accomplished using Datawave Technologies integrated A/D Card and patch panel. Your system can be configured to acquire from 1 to 128 channels of continuous or single sweep data.

All acquired data can be analyzed off-line following the experiment. Further, analysis can be performed during data acquisition, and both the raw data and the analyzed data can be stored for subsequent analysis and review during an offline session.

All data is timestamped to 1microsecond resolution, and this resolution can be held across several days of continuous recording.

Optional video tracking software is available.

Spike Recording

SciWorks Experimenter Configured for Single or Multi Spike Recording

This screen capture shows the Sciworks Suite configured for a typical spike recording session. The individual modules can be arranged anywhere on the screen the user sees fit. They can be sized, or replaced with other modules in a moment. Screen layouts can be stored for individual users, allowing multiple users to design customized displays for their own experiments.

EEG / Field Potential

This screen capture shows the Sciworks Suite configured for a typical EEG / Field Potential recording session. The individual modules can be arranged anywhere on the screen the user sees fit. They can be sized, or replaced with other modules in a moment. Screen layouts can be stored for individual users, allowing multiple users to design customized displays for their own experiments.

Data Analysis

DataWave Technologies® SciWorks® Experimenter 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.

Built-in analysis objects exist for many common experiment types:

  • Single Unit Recording
  • Multi-Unit Recording
  • Evoked Responses
  • Field Potentials
  • EEG
  • ECG / EKG
  • ERG
  • EMG

Included Data Analysis Modules:

  • Real time multi-unit spike sorting and separation using Autosort cluster analysis
  • Extract key waveform parameters, such as peak, valley, dV/dt, and more
  • Perievent time (PETH), Inter-event interval (IEIH) histograms and rasters
  • Detect and extract events based on software window discriminators
  • Can analyze in real-time during data acquisition
  • Cross Correlation histograms
  • Fast Fourier Analysis, including power calculations
  • Digital filtering, auto-baseline and waveform smoothing
  • Statistical calculations for waveform and single value data
  • Burst analysis for detecting both event and waveform bursts

Analysis for multichannel electrodes, such as stereotrodes, tetrodes, and high density arrays
