I made it mainly coping other scripts from the forum, so maybe is not the best piece of code. But the code seems to work properly for me. I want to change the two following things , after the code executes it creates a window with the fitting data, I want to avoid this!!! I only nead the peak of the curve an I alredy write this on a variable at the end of the code. Second thing I want to change, I don´t want to give initial values to the parameters of the fitting, when you do a gauss fit using the origin interface (Analysis:: FitGaussian) you don´t need to specify any values, so why do I have to initialize the parameters when I execute my script. If I don´t initialize the parameters the code doesn´t work. my script [main] rango1=%1; // data begin rango2=%2; // data end campo=%3; // field (dataset name) tem=%4; // temperature (dataset name) nlsf.init(); // initialize fit nlsf.dataBegin=rango1; // begin range nlsf.dataEnd=rango2; // end range nlsf.func$="Gauss"; // define function to be used during fitting nlsf.constr$=""; // clean ??? nlsf.fitData$=h$(campo)t$(tem)_re; // define data to be fitted nlsf.funcX$=h$(campo)t$(tem)_an;// X data to be used to create fit dataset nlsf.p1= 2; // initialize parameters nlsf.p2=260; nlsf.p3=30; nlsf.p4=10; nlsf.iterate(150); // perform 150 iterations pico=nlsf.p2; // write xc in pico variable nlsf.end(); [/quote]   Check here to include your profile signature.
