I think it depends of what the authors did i.e. what statistical model
they used so that they can have 'adjusted' data. Once you click VOI you
can adjust the data, i.e. look at data predicted by your model (adjusted
for confounds and filtered). For VBM however I don't really know what
kind of adjustment can be performed .. maybe other SPMers can answer
that (Marko?) If you used don't adjust this is the raw data.
