So I want to figure out which voxels were modulated significantly by the orientation of our stimuli. Is this the right file to look at? If so what are the real and imaginary components compared against? I want to know to make sense of the negative values.
It is the -log10(pvalue) where pvalue is the p-value from the F-test
of the real and imaginary components
