Lots of people used the coordinates of 6 ROIs provided by Fox et al., 2005 (Fox, M.D., Snyder, A.Z., Vincent, J.L., Corbetta, M., Van Essen, D.C., Raichle, M.E., 2005. The human brain is intrinsically organized into dynamic, anticorrelated functional networks. Proc Natl Acad Sci U S A 102, 9673-9678.).

For the first ROI (IPS) of the six ROIs (IPS, FEF, MT+, MPF, PCC, LP), the Talairach coordinates is: -25, -57, -46. [Methods -> Correlation Techniques]
However, this point sits in cerebellum!! Far away from the intraparietal sulcus (IPS).

I guess this is a typo in that paper, the correct coordinates should be -25, -57, 46. See foci in Table 1, IPS (-23, -66, 46) (25, -58, 52).

So be careful when using the coordinates from that paper.
