Welcome to Intron, Excon and UTR (IEU) explorer, an online tool to filter, sort, analyze and separate intron, exon and UTR sequences from the entire gene sequences. With the input of only gene and IEU data, 25 different kinds of data can be extracted from the gene sequence. Outputs can either be viewed online or downloaded for future standalone usage. The downloadable file is made for easy import with any standard spreadsheet application. The tool can also identify and report missing nucleotides within individual IEU sequences. To explore the different functionalities of this tool, please begin with your own set of sequences on the write hand side of this page or to learn more about this web-tool, go to either FAQ or Tutorial sections.
