Chromatic: WebAssembly-Based Cancer Genome Viewer.

Author information

Computational Genomics Research Group, Center for Biomedical Informatics and Information Technology, National Cancer Institute, Bethesda, MD, USA.


Chromatic is a novel web-browser tool that enables researchers to visually inspect genomic variations identified through next-generation sequencing of cancer data sets to determine whether such calls are, in fact, valid. It is the first cancer bioinformatics tool developed using WebAssembly technology, which comprises a portable, low-level byte code format that provides for the rapid execution of programs within supported web browsers. It has been designed expressly for ease of use by scientists without extensive expertise in bioinformatics.
