How to change IGB memory usage

If you used the IGB installer, then when IGB starts, it will use 25% of your system's memory. This means that when IGB runs on a machine with 4 GB of memory (RAM), it will use 1 GB. Or if IGB starts on a machine with 16 GB of RAM, it will use around 4 GB of memory. You can see how much memory IGB is using by looking at the lower right corner of the IGB window.

The only exception is when you run IGB on a 32-bit Windows computer. In that case, IGB will use 1GB of RAM.

You can change how much memory IGB can use.

There is a "vmoptions" file in your IGB installation directory which contains a commented-out jvm argument that sets the max heap size, which is the amount of memory IGB uses. 
To change the heap size, un-comment the jvm argument line and modify to suit your needs.

The vmoptions file on Mac is located in /Applications/Integrated Genome Browser/

On Linux/Windows, the vmoptions file is in ${IGB_INSTALLATION_DIR}/IntegratedGenomeBrowser.vmoptions, where $IGB_INSTALLATION_DIR is the folder where IGB resides.
