% There are 10 runs with 6 volumes per run. The runs are vertically stacked one
% above the other. The six volumes in each run correspond to the stimuli:
% 'monkey','lemur','mallard','warbler','ladybug','lunamoth', in that order. Add
% numeric targets labels (samples atribute) such that 1 corresponds to 'monkey',
% 2 corresponds to 'lemur', etc. Then add numeric chunks (another samples
% attribute) so that 1 corresponds to run1, 2 corresponds to run2, etc.
