This section describes the development and use of a toolbox of software programs for rapid data visualization of large-scale high-throughput datasets such as those found in The Cancer Genome Atlas (TCGA) and other multidimensional datasets. While the toolboxes are described in the context of cancer genomics and long noncoding RNAs, they can be easily applied for the visualization of any large-scale dataset in the form of box plots. The front-end of the toolbox is a simple graphical user interface (GUI), while the customizable back-end holds the data and has numerous modules related to various computations needed for genomic analysis.
