I will try to explain where I am at:

- set all the analysed patients in the tree (attachment);
- pick one of the patients to serve as reference, sent its Ictal SPECT node to space;
- clicked multiple images calculations, selected all ictal images;
- averaged to the reference in space;
- now went to the Interictal SPECT node (same patient), sent it to space;
- clicked multiple images calculations, selected all interctal images;
- averaged to the reference in space;


Now I have an Average.hdr, Stdev.hdr and Tscore.hdr for the Interictal SPECT and Ictal SPECT nodes.

What to do (considering that I had these steps right) now on?
