1 Introduction

This document explains how to install and operate the Plexon® OmniPlex® Demonstration (OmniPlex Demo) software.

2 Installing the OmniPlex Demo Software

The OmniPlex Demo software allows you to view and explore most of the features of the OmniPlex System, including filtering, spike detection, and spike sorting. It simulates acquisition of data from OmniPlex hardware by “playing back” a demo file of sample data. For additional information on the OmniPlex System, please contact a Plexon sales representative at [email protected] or +1 214-369-4957.

Operating System

The OmniPlex Demo software runs on Windows® 7 computers. In most cases, it can also run on Windows 10 computers. If you experience any difficulties installing or running the software, please contact Plexon Support at+1 214-369-4957 or [email protected].

Installed Items

The installation process will install the following items on the PC:

• OmniPlex Demo executables, data files, and User Guide

• Microsoft® Visual C++® 2013 redistributable items

• SafeNet® Sentinel™ security key drivers

Installed Files

The setup program has installed the following files on the hard drive:

• C:\PlexonData\wideband.ddt—16 channels of spike data riding on a 5 Hz sine wave meant to represent field potential signals

• C:\PlexonData\demo16.pxc—configuration file for PlexControl, containing sorted unit definitions

• C:\PlexonData\demo16.pxs—configuration file for OmniPlexServer

• C:\Program Files (x86)\Plexon Inc\OmniPlex\OmniPlexServer.exe and a shortcut icon on the desktop

• C:\Program Files (x86)\Plexon Inc\OmniPlex\PlexControl.exe and a shortcut icon on the desktop

2 A dialog will appear. Click OK.

The Server window opens.

3 From the Server File menu, select Open.

Version 1 13

4 Navigate to the folder C:\PlexonData.

7b Navigate to the folder C:\PlexonData.

7c Select and open the file "demo16.pxc."

7d From the Data menu, select Start Data.

Version 1 15

The PlexControl window displays the data from the “demo16”.pxc file.

8 To start using the OmniPlex Demo with no sorted units, i.e. "from scratch," perform the following steps in PlexControl:

8a From the Data menu, select Start Data.

8b From the Configure menu, select Auto‐Configure Sources.

8c Wait for the Auto Configure progress window to finish.

If you have questions about your OmniPlex Demo installation or operation, please contact Plexon support at +1 214-369-4957 or [email protected].

In the OmniPlex Demo, sample neural data is played back from the file wideband.ddt by a software emulator (TestADC) which takes the place of the OmniPlex Digital Headstage Processor (DHP) or DigiAmp data acquisition hardware. You can extract and sort spikes from the demo data file and try out many of the other features, displays, and techniques of the OmniPlex System.
