Does anyone know why it doesn't work? I added the script and the data below: Dataset dspos; pkfind iy:=(dsx, dsy) dir:=p npts:=5 value:=200 ocenter:=dspos; // Find major peak positions int npk=dspos.GetSize(); // Get major peak numbers // Create datasets to store anchor points int nn = dsx.GetSize(); // Get source X size dataset apt_x, apt_y;// Create datasets to store anchor points apt_x.SetSize(npk+1); // Set anchor points number apt_y.SetSize(npk+1); apt_x[1] = dsx[1]; // Set 1st data point as 1st anchor point apt_y[1] = dsy[1]; apt_x[npk+1] = dsx[nn]; // Set last data point as last anchor point apt_y[npk+1] = dsy[nn]; for (ii=1; ii<=npk; ii++) { int istart = dspos[ii]; // Get row index of ii-th peak int iend = dspos[ii+1]; // Get row index of the next peak range rtemp = [??]!dsy[$(istart):$(iend)]; // Declare the range and point to the loose dataset limit rtemp; // Get stats of the subrange int ind = limit.imin; // Get min Y row index apt_y[ii+1]=limit.ymin; // Get min Y between two peaks as anchor point apt_x[ii+1]=dsx[ind]; }; My data: 0.0355 0.03368 0.03186 0.03004 0.02823 0.02642 0.02462 0.02284 0.02106 0.01929 0.01754 0.0158 0.01408 0.01238 0.01069 0.00903 0.00738 0.00576 0.00415 0.00258 0.00102
