# iMOD User Manual version 4.4 (html)

#### 2.6Main Window

When iMOD is started, the iMOD Main window is displayed:

Important to notice that the graphical canvas can be modified, the location of the axes can be changed, as well as the position and size of the scale bar. Whenever the position of the mouse is near the current axes, the axes highlights in red and the cursor changes. At that moment, selecting the left-mouse button, it is possible to drag the axes. This is similar to the resizing and positioning of the scale bar.

The settings of the modified axes and scale bar are saved in the IMF file. Reopening an IMF file will show the modified axes and scale bar. The advantage of repositioning the axes is the ability to closely match the size of the current visible map, sush as a square IDF file.

Furthermore, this window contains a menu bar, an icon bar and information displayed on the window status bar.

To access the iMOD menus, click the menu names on the menu bar, or alternatively use Alt+$<$first letter of the menu name$>$.

Detailed descriptions of these menu options can be found in the Reference section.
