A database for identifying and visualizing CNAs in cancers at any specific region within the human genome. CaSNP stores pre-computed raw copy numbers, and dynamically generates viewable and downloadable summaries of CNA status in response to user queries. A schema for uniformly processing, storing, annotating and presenting data sets across different data sets or platforms was successfully implemented, making CaSNP a useful tool for cancer genomic meta-study. The query results contain numerical values of cancer copy numbers and the frequencies of CNA events, which are well suited for more detailed analysis by other software or methods. Besides the tabular display, the heatmap view displays SNP copy numbers in colors, enabling users to intuitively and comprehensively visualize the results and facilitating finding novel CNA regions in subset of samples.
