Use the getnlr x-function.
You need to use getnlr to get both the Parameters and Statistics results into a tree. For example, after performing a gaussian fit, and with the FitNL1 worksheet active, you can run the following (from either the Script Window or the Command Window):
getnlr tFitResults;
tFitResults.=;
You'll see the following output:
Data1 +---Name = Amplitude +---x1 = [Gaussian]Gaussian!Channel +---y1 = [Gaussian]Gaussian!Amplitude \---wmethod1 = No Weighting y0 = 5.3419788692313 e_y0 = 0.58340545321781 n_y0 = y0 xc = 24.906897224202 e_xc = 0.08666139607299 n_xc = xc w = 10.169692020721 e_w = 0.2045243560476 n_w = w A = 984.90203637016 e_A = 21.450750179376 n_A = A sigma = 5.0848460103603 ndp_sigma = sigma FWHM = 11.973897311092 ndp_FWHM = FWHM Height = 77.272559200605 ndp_Height = Height chisqr = 7.8157217446868 dof = 46. pts = 50. ssr = 359.52320025559 adjr = 0.98898685090753 fitstatus = 100 func = Gauss nfuncparams = 4. nderivparams = 3. nsets = 1.
To access any of these values in Script After Fitting code, saved with the fitting function and set to run after the fit is performed, you need to first create a tree object which will have the values loaded and then you can access them.
For example:
getnlr tr:=tFitResults iw:=__Report$ showall:=0 pnotation:=0; type -a; //output to the Script Window type chisqr $(tFitResults.chisqr); type status $(tFitResults.fitstatus); type y0 $(tFitResults.y0); type FWHM $(tFitResults.FWHM);
where __Report$ is an Origin string variable that holds the name of the last Analysis Report sheet created.
To see a list of all string variables that contain names of sheets created by analysis, go to script window and type
