SciWorks® Discovery

Intergrated Software Suite (A-M Systems)
Description

Comprehensive data acquisition and analysis software for any research protocol.
From 1 to 128 channels.

 

A-M Systems SciWorks Discovery software and advanced A/D hardware is the perfect complement to our low-channel count extracellular or intracellular amplifiers. It is designed to work with 1 to 8 single-ended channels of data. If you require more data processing capability, then consider our Discovery Pro system with more channels, optional video support, and a faster sampling rate. SciWorks Discovery is a real-time data acquisition, analysis, and instrument control application designed for a wide variety of electrophysiology experiments. It 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.

Common applications include:

  • Single-Unit Recording*
  • Multi-Unit Recording*
  • Evoked Responses
  • Field Potentials
  • EEG
  • ECG / EKG
  • ERG
  • EMG
  • Sleep Studies
  • Behavior
  • LTP / LTD
  • Voltage Clamp
  • Current Clamp
  • Dose Response Curve
  • Motor Unit Activity
  • Intracellular Recording
  • Respiration
  • Pulse Oximetry
  • Motion
  • Blood Pressure
  • GSR
  • Brainstem Evoked Response
  • Auditory Evoked Response**
  • Video Capture and Analysis***

* Discovery is limited to 3 channels simultaneously of spike recording due to bandwidth considerations.
** Discovery Pro only
*** Discovery Pro only; requires optional VideoBench Module

 

 

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

Discovery can be paired with a BNC breakout box providing direct access to the most critical connections of the A/D card or a screw-terminal accessory for a less expensive solution.

 

SciWorks® SciWorks Discovery Pro Data Acquisition And Analysis System

While SciWorks Discovery is the ideal data acquisition and analysis system for most electrophysiology experimental protocols, there are situations where upgrading to Sciworks Discovery Pro makes scientific and financial sense. If you are interested in acquiring and processing more than 8 channels of data, then upgrading to one of our SciWorks Discovery Pro options can give you access to up to 128 channels of capability. SciWorks Discovery’s underlying 8-channel data acquisition card’s clockrate is sufficient to generate simple stimuli. However, if your experimental protocols require delivering complicated stimulus trains, or auditory stimuli, then it is recommended to upgrade to SciWorks Discovery Pro. Finally, if your research protocols involve capturing, measuring, and analyzing video data, then SciWorks Discovery Pro with the optional VideoBench add-in is the software package to be used.

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.

 

Features of Discovery vs. Discovery Pro

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.

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.

 

SciWorks Discovery Or Discovery Pro 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
  • Coordinate timing among multiple external instruments
  • 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 (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

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.
