Analytic Tools


Computational method to calculate purity and ploidy of a given tumor sample. Determines the fraction of processed sample that actually contains tumor DNA from various data sources. Useful technique to distinguish between sub-clonal events and/or contamination.

The Integrative Genomics Viewer (IGV) is a stand alone piece of software developed at the Broad Institute to help visualize various types of genomic data including expression, sequence, copy number, etc. The full description and official software site is here.


The Genomic Identification of Significant Targets in Cancer (GISTIC) software package was developed at the Broad Institute to distinguish between actual molecular changes in copy number (amplifications and/or deletions) and noise from the array. The full description, publication, and software can be found on the site here.


This web portal is designed to facilitate the use and understanding of high resolution copy number data amassed from multiple cancer types specifically through the TCGA project. Pre-performed analyses include by gene and cancer type.
