Purpose

Recently, we proposed a standard for the exchange of electrophysiological recordings of vision, called Electrophysiology of Vision Markup Language (ElVisML). Here we present a Web 2.0 application, ElVisWeb, for visualizing data encoded in ElVisML. It intends to facilitate the exchange of recordings on mailing lists like CEVNet in a standardized way and to allow for sharing of data along with published articles.

Methods

Main goals of ElVisWeb were easy usage and deployment. It is developed completely in JavaScript and as web application it does not require any installation on the client. It uses the single-page-interface paradigm (SPI): An ElVisML-file can be pasted into a text-field and a graphical representation of it is compiled. ElVisWeb can be deployed on any web-server or executed locally. For convenience, there is an upload functionality, which requires PHP on the server, however. ElVisWeb leverages open source JavaScript libraries for XML-processing (Sarissa) and charts generation (jqPlot).

Results

A Web 2.0 application for visualization of electrophysiological recordings of vision, ElVisWeb, was successfully implemented. It is designed for easy usage and deployment. Recordings encoded in ElVisML can be visualized with no additional software installation.

Conclusions

ElVisML is a standardized way for exchanging electrophysiological data. ElVisWeb is a first step towards an open ecosystem around ElVisML. It provides chart generation for recordings and may be used in mailing lists like CEVNet or for sharing data along with published articles. It is also ready to be used on mobile devices.

How to

Follow the link above and upload an ElVisML file. Steps of a recording are shown in single tab which contains
single measurements. Click on the "Measurement information" button next to a chart to get detailed
information.
