Next-Generation Clustered Heat Map (NG-CHM) Detailed Overview

The Next-Generation Clustered Heat Map (NG-CHM) Viewer is a dynamic, interactive graphical environment for exploration of clustered or non-clustered heat map data in a web browser. For a basic introduction to clustered heat maps, their components and uses, please see our Introduction to Clustered Heat Maps.

The key components of an NG-CHM are:

labelled row and column axes,
one or more layers of data,
zero or more covariate bars on either axis, and
optional dendrograms for either axis.

A data type may optionally be given to the labels on either axis. For example, the row labels may be specified as gene labels, probe ids, metabolite names, and so on. Specifying a label type will add additional entries, such as link outs to related resources, to the Viewer's label popup menus.

NG-CHM Viewer

The NG-CHM Viewer is an interactive web tool that enables deep exploration of the patterns and associations in NG-CHMs. It can be used standalone or embedded in other tools and webpages.

Key features of the NG-CHM Viewer include:

scalable to thousands of rows and/or columns
summary view
multiple detail views
zooming
panning
searching
covariate bars
link-outs to dozens of external sources
interactive modification of map properties, including the map color scheme
ability to generate publication-quality static images
other data visualizations including 2D (UMaps, etc.), 3D Scatterplots, and Pathway Maps

Tutorial Videos

This short video (less than three minutes) briefly summarizes the key features of the NG-CHM viewer.

NG-CHM Builders

Creating NG-CHMs, as well as some computationally-intensive modifications (such as re-clustering), are the responsibility of the NG-CHM Builders. We support a variety of builders focussed on different types of user. For more information, use the navigator on the main NG-CHM page.
