Changing the memory limit

You can change the maximum amount of memory allocated to VisBio. Click the "Change..." button next to the "Memory maximum" value, and type a new value (in megabytes) into the dialog box that appears. This change requires the program to be restarted before taking effect. The new value must be at least 16, and should be 512 or greater to take advantage of many of VisBio's features. For high-resolution volume rendering at least 1280 is suggested. It is also recommended that you do not specify a value greater than the amount of physical RAM your computer has. Lastly, because 32-bit Java has a hard limit of 2048, specifying a value greater than 1800 or so may not work on many systems.

If you change the maximum memory value and VisBio then fails to load, then you have probably entered a value that is too large for your computer to handle. Reinstalling VisBio will fix the problem. Alternately, if you know what you are doing, you can change it back manually by altering the "-mx###m" value within the proper configuration file ("launcher.cfg" on Windows, "VisBio.app/Contents/Info.plist" on Mac OS X, or "visbio" on Linux).

If you are using VisBio's online distribution, please note that the memory limit is fixed at 512 MB and cannot be changed through the user interface.
