Next generation sequencing data is increasingly common in biological projects. Visualizing RNAseq data has become important in the analysis of sequencing data. IGV is the most widely used RNA-seq visualization tool, but it cannot simultaneously fully display other types of custom tracks that were introduced by the UCSC genome browser. This function is important because it enables researchers to simultaneously visualize gene expression at a particular locus from multiple experiments. Our visualization tool (RNASeqBrowser) presenting here offers a user-friendly interface for biologists.
