To set preferences, use Edit > Preferences (Windows) or SeqMan Ultra > Preferences (macOS 12 and lower) or SeqMan Ultra > Settings (macOS 13 and higher). This opens a three-tabbed Preferences dialog.

  • Use the Editor tab to choose whether or not to open alignments in a detached window.
  • Use the Internet tab to display or hide update notifications. Check the box if you would like SeqMan Ultra to display a notification when a newer version of Lasergene is available. Uncheck the box if you do not wish to receive this notification.
  • Use the Temporary Files tab to specify where SeqMan Ultra should store temporary files while a project is open. The need for temporary file space grows with the number and length of the sequences and amount of track data in open alignment projects. If you expect the temporary files will be too large to fit in the default location, you may specify a different location for these files using the Temporary Files Preferences dialog. To change the temporary file location, close all SeqMan Ultra projects and then return to this dialog. Select the Browse button, navigate to the new location and click OK. As noted in the dialog, the location you choose must remain accessible while SeqMan Ultra is running. The new location will be used for all projects that are subsequently created or opened.

Click Apply to save your changes while keeping the preferences dialog open, or Apply and Close to save the changes and exit from the dialog. To return to default settings, click Restore Defaults. To leave the dialog without applying changes, choose Cancel.
