Dear SPMers,
i would be very happy about somebody answering these questions for me:
(1) for what kind of confounds are the fitted and adjusted y data you get
after plotting exactly adjusted for. Do these adjustments depend on the
userīs specification or are there any defaults, any confounds these data
are always adjusted for? And what kind of computations are applied to the
data adjusting them? Is the variance explained by these confounding
variables just partialed out? I presume the adjustments for high- and low-
pass-filtering are those i specified in the model.
(2) Is it a reasonable procedure to extract these y data for the voxel of
interest and use them for correlation analyses with other
psychophysiological variables?
Thanks in advance,
Julia
