Origin Ver.8 and Service Release (Select Help-->About Origin): SR4
Operating System: Windows XP
Hi,everyone.
I have used the PFM (Peak Fitting Module) in origin 7.5, which is changed to Peak Analyzer in origin 8.
In PFM, the process contains smoothing of the data, baseline, background subtraction (such as shirley for XPS data), and so on before defining the peak position, but in Peak Analyzer, it only has baseline for peak fitting, therefore, i can not do my process very well in origin 8.0, i think the PFM in origin 7 is better.
So my problem is whether i can use the PFM in 8.0, or there is other way to do the process similar to PFM in 8.0.
Best regards,

Hi Feiliiao,
We have added XPS baseline recently and this will be available in the next service release (SR5) which should be out around mid to late February. Apologies for the inconvenience on this.
As for smoothing, we decided not to put that into this tool, as that is available outside (Analysis menu, Signal Processing, Smooth...) So any preprocessing such as smoothing and filtering can be done on the data before you launch the Peak Analyzer.
In SR5 the Peak Analyzer will also support Recalculation, so if you smooth your data, then do peak analysis, and set both operations to update automatically, you will then be able to simple change input data and both operations will update to give final results - if automation for many datasets is of interest.

Dear easwar,
Thank you for your answer.
In my case, i need to do the peak fitting several times before i can get satisfied results. So, i do all the preprocessing with the PFM.
May be you are right, i should do the preprocessing before using peak anlyzer.
I hope the peak anlyzer become more strong in the future for XPS data processing.
Thank you.
