Dear Suresh_kumar Is it possible to use NPLS in case of PARAFAC (Fluoresscence) using Unscrambler's. | ||

SELECT in WinISI is similar to Unscrambler's Edit - Mark - Evenly Distributed Samples Only. So its simple Just Go to Edit-Mark-Evenly Distributed Samples Only | ||

I am the user of PLS tool box and Grams\AI. I have recently advised to work on "R: language " by NIR work group. I feel it is more comforatble and GLP language . I have used Rlanguage as Backround and VB/VC++ as front end . I feel alot fo think we can explore in R. | ||

Thanks for the replies. I was thinking there might be a way to manually mimic the select algorithms used in other programs by using the Unscrambler plots. Maybe by selecting representative samples for neighborhoods I define in the score space following PCA? I'm obviously looking for an efficient way, so I will go back to ISI if there is no easy way with Unscrambler. Cheers, | ||

In the Unscrambler is not available any option related to the efficient sample selection for calibration models. If you are referring to local calibrations (NON-LINEAR CALIBRATIONS), these algorithms are not available in The Unscrambler. I suggest you use the mathlab PLS toolbox and explore others Best wishes, Leonardo Ram�rez-L�pez Graduate Student at University of S�o Paulo Department of Soil Science | ||

That's easy. Once you see the data table,go to the Edit menu, then click "select sample...", or "Select variable...", whichever you want to select. Have fun! | ||

Hello, Can anyone spell out a procedure to use in the Unscrambler similar to "SELECT" in WinISI, for the selection of a representative calibration set from a larger set of spectra? Cheers |
