Hi,
there is a peculiar problem with the labtalk comand
curve.SGSmooth()
in Origin Pro 7.0 (B522 SR4, with German WIN98)
my script looks like this:
curve.data$=SOURCE_C;
curve.x$=SOURCE_X;
curve.result$=RESULTS_B;
curve.polydeg=3;
curve.smoothleftpts = 25;
curve.smoothrightpts = 25;
curve.SGSmooth();
I now expected the execution of smoothing over 51 points of Source_c, but instead, Origin sets curve.smoothleftpts and curve.smoothrightpts back to the default value of 2 prior to execution of the smoothing, and then performs the smoothing over 5 points only!
The only way to execute smoothing with preselected value for the smoothranges seems to be the selection via the Origin-Analysis-Smoothing menue. Once these values are set "by hand" they remain unchanged after repeated smoothing. But, of course that is no solution, because I would like to do the selection automatically via the labtalk script.
Any explanation or hint?
Thanks
Stefan

Hi Stephan,
Alter your script like this...
curve.data$=SOURCE_C;
curve.x$=SOURCE_X;
curve.result$=RESULTS_B;
curve.polydeg=3;
curve.smoothleftpts = 25;
curve.smoothrightpts = 25;
curve.smoothpts = 51; // total smoothing pts
curve.SGSmooth();
The default value of curve.smoothpts is 5 so leftpts and rightpts are reset if you forget to change it.

Hi Mike, thanks!
anyway, it seems a bit strange to me that one has to set the left and right hand no of points as well as the total no of points.....
