軟件

PlexControl：PlexControl 是 OmniPlex 系統(tǒng)*的在線spikes排序軟件，具有靈活和可定制的主要用戶界面。該軟件代表了下一代信號(hào)可視化和易于使用的spikes波形分類方法，并允許研究人員與系統(tǒng)交互。它具有易于使用的信號(hào)可視化、spike檢測(cè)和排序算法。有許多spikes排序方法可用，包括：box, template, line, bａnd sorting in time/voltage space and contour sorting in PCA feature space feature space。PlexControl 程序會(huì)在每個(gè)通道上自動(dòng)獲取用戶定義大小的spike波形快照，并可隨時(shí)查看以根據(jù)需要修改spike排序參數(shù)?？梢愿鶕?jù)實(shí)時(shí)數(shù)據(jù)的快照或直接實(shí)時(shí)"繪制"實(shí)時(shí)數(shù)據(jù)來定義單位。每種方法可用于在線 single electrodes, stereotrodes and tetrodes排序。

連續(xù)spike、場電位和信號(hào)可方便地顯示在 PlexControl 靈活、可定制的用戶界面中，以及檢測(cè)到的spikes波形段及其相關(guān)的二維 （2D） 和三維 （3D） 功能空間集群，用于在線spikes排序。此外，所有三種數(shù)據(jù)類型以及閾值spike波形段和數(shù)字事件數(shù)據(jù)都可以記錄到每個(gè)通道的磁盤中。

OmniPlexServer：OmniPlexServer是PlexControl控制下的"引擎"。它可直觀地顯示系統(tǒng)中的各種硬件設(shè)備（例如headstages, amplifier）和軟件模塊（例如spike和 LFP 分離器、閾值、排序）。它從 OmniPlex chassis和放大器獲取數(shù)據(jù)，向這些設(shè)備發(fā)送命令，并實(shí)現(xiàn)軟件數(shù)字信號(hào)處理 （DSP），用于 OmniPlex 的過濾、spike檢測(cè)和spike排序功能。OmniPlex Server 基于模塊化、可擴(kuò)展的框架（或拓?fù)洌┯布蛙浖O(shè)備，這些設(shè)備在數(shù)據(jù)流拓?fù)渲邢嗷ミB接，利用拓?fù)湎驅(qū)褂脩裟軌蜉p松定義自定義配置，而無需繁瑣的低級(jí)編輯。

OmniPlex 軟件與 Plexon 的 MATLABａnd C/C++ API 和客戶端開發(fā)套件（SDKs）以及在線神經(jīng)探索器鏈接兼容，實(shí)現(xiàn)了低延遲、閉環(huán)實(shí)驗(yàn)和實(shí)時(shí)數(shù)據(jù)在線分析。Plexon 的 PlexNet 協(xié)議支持跨任何 TCP/IP 或 UDP 網(wǎng)絡(luò)進(jìn)行遠(yuǎn)程在線數(shù)據(jù)訪問，以及用于修改 OmniPlex 軟件輸出的PlexUtil，還可以進(jìn)一步加強(qiáng)該功能PLX數(shù)據(jù)文件。此外，OmniPlex 中的靈活數(shù)字過濾功能也納入離線排序程序，使用戶能夠?qū)⑾嗤臑V鏡離線應(yīng)用到與在線使用的數(shù)據(jù)持續(xù)采樣。

OmniPlex 軟件，通過購買任何 OmniPlex 系統(tǒng)預(yù)加載到控制計(jì)算機(jī)上。OmniPlex 軟件的演示版本（無需 OmniPlex 硬件即可運(yùn)行）可在此頁面頂部找到。
