Hello Origin Users,
Attached is a mass spectrum with so many peaks (marked by red circles). Zoomed inset showing each of those peaks with a gaussian distribution. I want to normalize those peaks such that intensities from 0 to 1.
There are so many peaks in here; is there a way I can specify x ranges for each of those peaks and normalize all in one go?
Thank you,
Neena |

This is because your data has large noise. Can you do the normalization with the two steps below?
1. Normalize the peaks as I suggested. But not to 0-1 but to a larger range, say 0-100000.
2. Normalize the entire spectrum to 0-1.

I will make my question more clear:
I finally want a mass spectrum with normalized intensities of all those peaks (completed!) and see the gaussian distribution of all those peaks in one spectrum (so I want to remove those white spaces in between).
Any insight would be appreciated,

Thank you James, that method you sent via animation works perfect!
Follow up questions:
1. Those red margins were deleted, however there are still black margins that I cannot remove (shown below).
2. How to remove those white spaces in the x-axis where I do not have any data. 
Many thanks,
