Origin Ver. and Service Release (Select Help-->About Origin): 8.0, and 9.0
Operating System: Win7
I have sets of data acquired from an oscilloscope, and I want to fit them. The problem is that there are too many data points that fitting is very slow. What is a simple way in Origin to export into a new worksheet the data from every other row or every 5 row?
I've been using Origin 8.0, but the company just bought Origin 9.0, so I might get access too. Instructions in both versions would be greatly appreciated. |

We also have Analysis: Signal Processing: Decimation... menu which will open a dialog for you to downsample data in OriginPro. That's not in Origin 8 though.
Thanks, Snow Li

Hi,
There are several ways in Origin 9 to reduce data. For example Data Filter, Analysis:Data Manipulation, Worksheet:Reduce Rows and Worksheet Query. Our website has a page summarizing methods for Data Manipulation:http://www.originlab.com/index.aspx?go=Products/Origin/DataAnalysis/DataManipulation . You can click on each of them I mentioned, and refer to tutorials, documentations or even video tutorials for instructions.
In Origin 8, you might try Worksheet Query since the others are not available.
In Condition, what you should enter to extract every 5 row stating from the 1st row is:
mod(i - 1, 5)==0
Also refer to this: http://www.originlab.com/www/support/resultstech.aspx?ID=135&language=English&Version=All
All the best,
Meili
