The Integrative Genomics Viewer (IGV) for iPad, is an open-source lightweight viewer for browsing genomic data on Apple iPad tablets. IGV for iPad is based on our popular IGV application for desktop and laptop computers. IGV for iPad offers a select subset of commonly used data types and features from desktop IGV. IGV for iPad supports a variety of data types that can be displayed in the context of genomic coordinates, for example, DNA and RNA sequence alignments, copy number, mRNA abundance, ChIP-Seq data, and others. The app provides convenient access to a number of publically available datasets, but you can also load any dataset for viewing in IGV for iPad, provided you have the web address and it is in one of the supported formats.
