Download the Integrated Genome Browser

To download and launch the newest version of IGB (old versions are here), select an icon below.

New: Click here to download a preview, alpha release of IGB 6.7. Intensive testing is underway and we aim to have a final version available on our Web site by the end of January.

Problems getting IGB to run? If you are having problems getting IGB to run, please consult the IGB User's Guide troubleshooting section. Most problems arise from trying to give IGB more memory than you computer allows. The TroubleShooting section will help you (and us) diagnose the problem. And, if all else fails, you can contact us for more help. (Email aloraine@uncc.edu or agulledge@uncc.edu for personal assistance.)

You can also obtain a copy of the latest stable release of the IGB software as a "zip" file from the SourceForge Web site: http://sourceforge.net/projects/genoviz. Previous versions are also available just in case you need them. Just open the zip file and double-click run_igb.bat (Windows) or run_igb.command (Mac, Unix) to start IGB.

Which IGB Should I Use?

Most people should use the 1 gig version of IGB (leftmost button), which will take up a maximum 1 gig of memory on your computer. If you run into a problem loading a large data set and are running a 64-bit operating system, you can launch the 2GB or 5GB versions of IGB which will allocate two gigabytes (or five gigabytes) of memory for IGB.

Note that if you attempted to launch one of the larger memory versions of IGB and get an error message that says something like "Unable to Launch Java Virtual Machine," it just means your computer (probably) does not have enough memory to run the larger memory versions of IGB. If that happens, clear your browser cache and try again using the smaller memory version.

How Do I launch IGB?

When you click the icon, your browser will download and launch the IGB software using a mechanism called Java Web Start.

The button is linked to a JNLP file, which your browser will download, parse, and then use the information it contains to request the software to download onto your computer.

Some browsers will ask you what you want to do with the JNLP file (instead of automatically downloading it somewhere, or presenting it to you as text). If a dialog appears with "Open using application..." on it, use the javaws application to run your file (and check the box marked "Don't ask me again"):

• <path to java runtime installation>/bin/javaws
• <path to jdk installation>/jre/bin/javaws
• javaws.exe

If you think that your browser should really be working with Java properly, you can test it at Java.com.
