data-icon Data Viewer

A module of the data portal designed for viewing and exporting Ephys and Genome data.

Overview

This document describes how to use the data plotting viewer tool available on the SPARC Data Portal. Examples of this tool in action are available at https://data-viewer-demo.netlify.com/.

This module has the ability to:

  • Plot electrophysiological CSV datasets in the knowledgbase or Blackfynn.
  • Plot genome and other static CSV datasests.
  • Navigate large datasets via the user interface.
  • Add and remove channels from a plot and export them.
  • Export selected channels as CSV for use in Excel or OpenCOR.

Viewer Configuration

The viewer has two modes, for small and large datasests.

Small Datasets

This mode is used for smaller datasets and has more control over exports. (All checked channels will be exported.)
