= Cursor =

The cursor serves two  main purposes. It acts as a central focus point when multiple  viewing panes are open, and it selects a voxel whose information  will be displayed in the Tools Window. It also serves as a kind of  bookmark for sharing cursors with TkSurfer, as a centroid for  rotation, selecting a voxel to be graphed in the Time Course Window,  and other various functions, explained later.

== Linked Cursor ==

When the viewing area  is split into multiple panes, each panel may have a separate cursor  location. If cursor linking is active, setting the cursor in one panel will set the cursor in all panes. Cursor linking can be  activated with the {{attachment:Icons/TkMedit/icon_linked_cursors.gif}}  button on the Main Toolbar.

For example, in the  Multiple Views configuration, setting the cursor in the coronal  pane will change the slice in the horizontal and sagittal  planes. So the cursor becomes a way of navigating through the  volume using the three orientations.

Depending on the  viewing configuration, with Linked Cursors active, other  attributes are linked as well, including zooming and display flags. In Mosaic View mode, only the in-plane cursor coordinates  will be linked, so the slice in each pane will be the  same. However, if the slice number is increased in one pane, the  slice number will be increased in all other panes.

== Cursor and Mouse Information ==

The bottom of the  Tools Window displays information about the voxel under the cursor  (on the left) and the mouse (on the right). The information  displayed depends on the kind of data loaded. If only an  anatomical volume is loaded, only the volume index coordinates, volume Talairach coordinates, and volume value will be  displayed. (If for some reason a Talairach transform could not be  found, RAS coordinates will be displayed instead.)


As other data are  loaded, more information will appear in this area. For example, if  a functional overlay is loaded, the functional overlay value will  appear in this area. Alternatively, the data shown can be changed  in the '''View->Information''' menu.
