The Object Configuration widget is available only if a subject file is currently loaded in Surface3D.

• Subject This field is automatically populated with the ID of the subject when you load a subject file.

• Session This drop down menu is automatically populated with all of the sessions available for the current subject.

• Object This list is automatically populated with all of the objects in the current session. Each object is enabled if it either has a segmented image file specified for it, or if there is scan data specified for the session. Selecting one of the objects loads its segmented image file, if it has one. If it does not, a dialog is displayed containing all of the scan data files specified for the session, allowing you to select one of them for segmentation.
