Converting Atlas VOIs to Contour VOIs using Outline

Unlike contour VOIs, atlas VOIs cannot be adjusted. Therefore, a mechanism has been implemented in the PMOD VOI tool to convert atlas VOIs into contour VOIs. The procedure is very simple:

1. Select the atlas VOIs for which contours should be generated (Template/Atlas/AAL-VOIs).
2. Activate the Outline button.
3. Save the contour VOIs.

The illustration below shows the example of an image in the MNI space with the AAL atlas selected. The AAL VOIs are organized as a tree structure.

Using Outline results in the following contour outlines shown on the List tab.
