A map is a file which contains integer pixel values called object labels. The labels typically identify different objects in the image volume. Such maps are often the product of segmentation procedures.
Map files in different image format can be loaded into PMOD. In the VOI page of the View tool map files can be converted in contour VOIs. The functionality is located in the Tools tab:
When Outline Maps option is selected a dialog window appears which allows specifying the bin size for the label histogram.
A Step value of 1 should normally work fine. The file is scanned and for each label found a contour VOI is created. Now the names can be edited and the VOIs saved.
An alternative is direct loading of label maps via that Template functionality as described below.
