It seems to work okay when I try to subtract backgrounds from my original data. I, however, do not understand the algorithm to fully trust the result. Especially, I wonder how you can subtract background when the x points of original data and background data are different. Could anyone have any idea about the subtract algorithm? Thank you in advance. [/quote]   Check here to include your profile signature. Check here to subscribe to this topic.
