[FieldTrip] removing EEG 1/f spectral power

Hi  FieldTrippers,
   I am interested in studying the spectral peaks in resting EEG.
Identifying these peaks is complicated by the 1/f distribution of EEG
power.  Do any of you have suggestions for removing the 1/f
distribution to better reveal peaks?  I've seen people suggest
autoregressive modelling or applying high pass filters but in the
couple of attempts I've seen the results look fair.
    much appreciated,
      -David
