Origin 8.0.63.988 SR6
v8.0988
Operating System: Windows

I wrote a loop-based program that runs the pkFind function on several data columns contained in several data sheets.
If the function pkfind cannot find any peaks, it stops and shows an error message asking me to change my parameters.
But I would like it not to stop and to move on to the next sheet.

How can I do that ?

Thanks

You could use a pair of curly braces ("{" and "}") to enclose a part of the script that might generate an error. Then Origin will encounter the error and resume with the rest part of the script, which is outside the braces.

The following page has given a example to show you how to do this.

Use the -sb option switch within your pkfind-command. This will prevent the X-Function to report errors and results to the results log.

Look inside of the LabTalk-Help for chapter 'X-Function Execution Options'. There you will find a complete list of option switches for all X-Functions.

Example:
pkfind -sb dir:=b method:=max smooth:=200 ocenter:=peakindex ocenter_x:=peakx ocenter_y:=peaky iy:=(targetx,targety);

Regards,
Steffen
