After aggregation has been started, a dialog window appears with the first page 1 Select components open.
It lists all VOI statistics (.voistat files) which are available in the selected DATABASE.
The task on this page is to select the statistics components which should be concentrated into a single aggregate. This is done by selecting the appropriate entries in the list so that they appear highlighted, in the example above the ones of the healthy controls (see above). Note the filter elements in the upper part which allow reducing the number of listed components. For instance the string H* could be entered in the Subject Name field to list only the results for the controls.
If no database has been used for saving the .voistat files, the Load from File System function has to be used instead.
