= Interface =
TkMedit consists of two windows. The Display Window displays data. The Tools Window has toolbars, a menu bar, and display areas for the cursor and mouse location.

== Display Window ==
{{attachment:tkmedit_interface_display.jpg}}

Here is a look at the program. In this instance, TkMedit is showing the 'orig' volume of a subject named bert-brf as the main volume, and the 'brain' volume as the auxiliary volume. A functional overlay is also loaded.

TkMedit can have two anatomical volumes in memory, the Main and Aux volume, but only one is displayed at a time. To toggle between these, use the alt-c keyboard command, the toolbar buttons ( {{attachment:icon_main_volume.png}} and {{attachment:icon_aux_volume.png}} ), or the '''View->Main Volume / Aux Volume''' menu commands. The currently displayed volume has a pair of asteriks around its name in the title bar and in the Tools Window.

The cursor in the Display Window is drawn in red and has additional guide marks on the side of the window. The cursor is the center of the current viewing location. If you switch to a different orienation, the cursor will still be visible.

You can resize the Display Window to stretch it out, but be aware that non-square window sizes will cause distortions.

== Tools Window ==

The menu bar on the top of the Tools Window contains four menus. The File menu is for loading and unloading data and for saving changes. The Edit menu contains undo utilities. The View menu contains options for specifying what data is displayed and configuring how it is displayed. The Tools menu contains commands and utilities for working on data.

There are two toolbars visible by default; in this picture, the middle toolbar is visible as well. The Main toolbar has buttons for selecting the different tools, as well as the surface display, and for toggling between the Main and Aux anatomical volume. The Navigation toolbar lets you switch orientations, zoom in and out, change slices, and load a cursor location from TkSurfer. The Reconstruction toolbar contains tools that aid in the reconstruction pipeline.  Hover your mouse over any button to see the corresponding shortcut key.

Underneath the toolbars is an area divided into halves. Each half displays information about the cursor (left half) or mouse location (right half). This area expands downwards as more data types are loaded and have information that needs to be displayed.

Additionally, the coordinate displays here are editable. If you enter coordinates into the appropriate field and press enter, the cursor will move to that location.
