Ngene version 1.4 is now available and recommended for all users (including as a free update to existing users). The version has a range of bug fixes, stability improvements, extra syntax checks, and updates to the manual. Ngene now randomises which levels appear more for unbalanced attributes with the swapping algorithm. Also, reject and require constraints are now applied if a loaded candidate set is used with the Modified Fedorov algorithm.
The easiest way to update Ngene is to select "Check for updates" from the Help menu. The software can then be downloaded and the update started from within Ngene. Alternatively, download the installer from https://www.choice-metrics.com/download.html#software and install the software.
If you have any feedback on this version, email us at contact@choice-metrics.com. Also use this email address if you have any technical problems completing the upgrade.
