Origin Ver. and Service Release (Select Help-->About Origin): 9.1
Operating System win 7

Hi!
We would like to add a function to an import script where we normalise the data to start from one.
We have a near exponential relaxation function which we would like to start from 1.
Any suggestions to how we can do that- preferably not be dividing by the first value as individual numbers contain errors.

Thanks

Hi,

If you just want to normalize your data to make it start from 1, you can simply use the Normalize Column tool: Set Normalize Methods to Divided by Reference Cell and select first cell as Reference Cell:

You said "preferably not be dividing by the first value as individual numbers contain errors." Is this tool not satisfying for you? Can you give me more details about what you want and show me your data?

Thanks,
Shirley

Hi!

thanks a lot- I am creating a script to process the data. I have typical x, y columns and during import I want to normalise the y data to 1.
I write typically

%H_Y = (%H_Y - Background_Y*0.995);

How can I normalise %H_Y in a script form?

Best,
