Hi Xi-Nian, As Doug said, they don't do the same thing. The method in the paper uses a different kind of interpolation to allows the preservation of the amount of area, whereas mris_preproc achieves the same globally using a Jacobian correction. The results aren't expected to be identical at the vertex level or for small regions.
An implementation of the method we proposed in the paper is available for Octave and/or Matlab at http://brainder.org/download/areal It works fine, but beware that it's quite slow.
