TCGA-Assembler is an open-source, freely available tool that automatically downloads, assembles, and processes public The Cancer Genome Atlas (TCGA) data, to facilitate downstream data analysis by relieving investigators from the burdens of data preparation. TCGA-Assembler includes two modules. Module A acquires public TCGA data from TCGA Data Coordinating Center and assembles individual data files into locally stored data tables. Module B does various manipulations on the data tables to prepare them for downstream analysis.

Zodiac provides a comprehensive depiction of cancer genomic interactions inferred by Bayesian Graphical Models (BGM) based on multimodal The Cancer Genome Atlas (TCGA) data, including gene expression, protein expression, DNA methylation, and copy number. Zodiac consists of two main components, 1) a large database containing nearly 200 million regulation maps of intragenic interactions of each gene and intergenic interactions between each pair of genes, and 2) analytics tools that perform high-quality inference on data-enhanced networks based on either multimodal TCGA data or user's in-house data.

- VIsual Statistical Data Analyzer (VISDA)
VISDA is an analytical tool for cluster modeling, visualization, and discovery. Being statistically-principled and visually-insightful, VISDA exploits human gift for pattern recognition and allows users to discover hidden clustered data structure within high dimensional and complex biomedical data sets. The unique features of VISDA include its hybrid algorithm, robust performance, and "tree of phenotype". With global and local biomarker identification and prediction functionalities, VISDA allows users across the cancer research community to analyze their genomic/proteomic data to define new cancer subtypes based on the gene expression patterns, construct hierarchical trees of multiclass cancer phenotypic composites, or to discover the correlation between cancer statistics and risk factors.
