IGV 2.0 Feature Guide

IGV 2.0

This guide details major feature updates for  IGV version 2.0.  

New Java Requirement

If you are launching the IGV client and you encounter an error message that tells you that you have a bad version number, ensure that you are running  Java 6.

IGV 2.0 requires that Java 6 or later be installed on your computer (previous versions of IGV required Java 5 or later). If you do not know which version of Java you are currently running, try running this Web site: Java Tester

For Windows: Java version 6 is available for download from Sun. Download here.

For Macintosh: All Macs running Leopard or after should have Java 6 installed on them. On some Macs the download fails when launched from Firefox 3.x. The error message under "details" will say something about an unsupported class version. For unknown reasons, Firefox sometimes tries to launch the app with Java 5, rather than Java 6. Safari launches correctly, as does Firefox 4.x. If you get this error, Java 5 may be the current default. In order to set Java 6 as the default on Leopard:

  1. Open Applications>Utilities>Java>J2SE 5.0>Java Preferences.
  2. In the Java Application Runtime Settings section, drag J2SE 6.0 above the other J2SE items.

In order to set 6 as the default on Snow Leopard:

  1. Open Applications>Utilities>Java Preferences.
  2. In the General tab, make sure the Java SE 6 checkbox is the only one selected and drag that line to the top of the list.

If you don't have 6 on your machine, Apple supplies their own version of Java. Use the Software Update feature (available in the Apple menu) to check that you have the most up-to-date version of Java for your Mac. 

If you are unable to resolve this issue, please post a help request at the igv-help forum.
