Alignment Mode

Alignment mode allows you to automatically correct position, rotation and size errors and select which parts of the subject are to be positioned at the stereo-window.
It is recommended that you first correct rotation and size errors and then repeat to set the window.
If you need greater point-selection precision than the SPM cross-hairs provide, you may use a magnifier utility (such as provided with WinME/XP).
Be aware though, that pixel arithmetic is not particularly precise so you may see little difference in the finished result.

Select the 'Alignment Mode' tool button (or Push 'Ctrl+A' key' or Select 'Menu/Adjust/Alignment Mode')
