This command displays a dialog box that allows users to control the behavior of CTSim. These options are saved across CTSim sessions. Under Microsoft Windows environments, they are stored in the registry. On UNIX and Linux environments, they are stored in the user's home directory with the filename of .ctsim.

Advanced options This option is initially turned off in new installations. These advanced options are not required for normal simulations. When Advanced Options is set, CTSim will display more options during scanning of phantoms and the reconstruction of projections.

Ask before closing new documents This option is initially turned on in new installations. With this option set, CTSim will ask before closing documents that have been modified or never saved on disk. By turning off this option, CTSim will never ask if you want to save a file -- you'll be responsible for saving any files that you create.

Verbose logging This option is initially turned off in new installations. With this option set, CTSim will log more events than usual. There extra events are not important for viewing with typical operation of CTSim.

Show startup tips This option is initially turned on in new installations. With this option set, CTSim will display helpful tips when CTSim is started.

Run background tasks This option is initially turned off in new installations. With this option set, CTSim execute lengthy calculations in the background. A background window will appear when processes are running in the background and will disappear when no background processes are executing. This background window shows the status and progress of all background processes. NOTE: Due to limitations of wxWindows, this function is only supported on Microsoft Windows.
