An image series for which a set of contour VOIs has been defined can easily be converted into a template as follows:
A dialog window appears which requests a name for template. Using this name a subdirectory with is created in resources/templates/voitemplates, where the image series is saved in NifTI format, and a text file with the VOI names is created. After activating the refresh button in the Atlas pane of Template, the new template appears and can be used for statistics.
