Examples

res=makeSimulatedData();
X=res$data;
groupLabel=res$label;



peakList <- detectSpecPeaks(X,
  nDivRange = c(128),                
  scales = seq(1, 16, 2),
  baselineThresh = 50000,
  SNR.Th = -1,
    verbose=FALSE
);


resFindRef<- findRef(peakList);
refInd <- resFindRef$refInd;


maxShift = 50;
Y <- dohCluster(X,
                peakList = peakList,
                refInd = refInd,
                maxShift  = maxShift,
                acceptLostPeak = TRUE, verbose=FALSE);

# find the BW-statistic
BW = BWR(Y, groupLabel);
