The recipe I used below was one taken from the docuemnetation for peakDim.numAliasing in the data model numAliasing Int <cid:part1.02090406.04030402@bmb.leeds.ac.uk> 1..1 number of aliasings. The real peak position is defined as positionPoints + numAliasing*dataDimRef.dataDim.numPointsOrig and I wasn't sure which was correct and if there were any inobvious implications so i chose one (are they equivalent? is one preferred?) regards gary >Yours, > >Rasmus > >--------------------------------------------------------------------------- >Dr. Rasmus H.
