Reporting bugs

Our public bug tracker is on GitHub at https://github.com/NetLogo/NetLogo/issues. You can look here to report a new bug, check if a bug has already been reported, and so on.

When submitting a bug report, please try to include as much of the following information as possible:

• A complete description of the problem and how it occurred.
• The NetLogo model or code you are having trouble with. If possible, attach a complete model. (It’s best if you can reduce the amount of code in the model to the minimum necessary to demonstrate the bug.)
• Your system information: NetLogo version, OS version, Java version, and so on. This information is available from NetLogo’s “About NetLogo” menu item, then clicking the System tab.
• Any error messages that were displayed. Please copy and paste the entire error message into your email, or make a screen capture if you are unable to copy and paste.

We also accept bug reports by email at bugs@ccl.northwestern.edu.
