Hallo Peter, thanks for the files. unforunately, the otimize.pl still doesn't show the result of the fit (plot is there) output is in a shortened version:
Fit of: E = a1 + a2*x + a3*x^2 + a4*x^3 + a5*x^4 a1 1.000 a2 0.000 1.000 a3 -0.725 -0.000 1.000 a4 -0.000 -0.930 0.000 1.000 a5 0.648 0.000 -0.985 -0.000 1.000 the line 174 should contain at least tail -15 (instead of -5) what results in the output of the parameters and the correlation matrix Fit of: E = a1 + a2*x + a3*x^2 + a4*x^3 + a5*x^4 Final set of parameters Asymptotic Standard Error ======================= ========================== a1 = -5573.9 +/- 3.634e-06 (6.519e-08%) a2 = 4.23124e-06 +/- 9.205e-06 (217.5%) a3 = 0.000137795 +/- 2.93e-05 (21.26%) a4 = 7.61902e-06 +/- 1.037e-05 (136.1%) a5 = -1.43164e-05 +/- 2.725e-05 (190.3%) correlation matrix of the fit parameters: a1 a2 a3 a4 a5 a1 1.000 a2 0.000 1.000 a3 -0.725 -0.000 1.000 a4 -0.000 -0.930 0.000 1.000 a5 0.648 0.000 -0.985 -0.000 1.000 or shorter versuion is to use tail -15 fit.log | head -7 because I don't think that the correlation matrix is needed in the w2web output (it's found in fit.log anyway) the result is then only Fit of: E = a1 + a2*x + a3*x^2 + a4*x^3 + a5*x^4 Final set of parameters Asymptotic Standard Error ======================= ========================== a1 = -5573.9 +/- 3.634e-06 (6.519e-08%) a2 = 4.23124e-06 +/- 9.205e-06 (217.5%) a3 = 0.000137795 +/- 2.93e-05 (21.26%) a4 = 7.61902e-06 +/- 1.037e-05 (136.1%) a5 = -1.43164e-05 +/- 2.725e-05 (190.3%) the optimize.pl file changed in the latter way is attached Ciao Gerhard DEEP THOUGHT in D.
