Origin’s Peak Analyzer is a powerful tool to perform peak analysis of many different user scenarios. For example, in the graph below, there is a peak located near x=260 but data points are not available for the entire peak. With proper … Continued
One scenario frequently encountered in batch peak analysis is the peak positions keep changing between datasets. It would be helpful for the peak analysis tool to remember the fitted parameters from the last dataset and use them as the initial guess for … Continued
When learning artificial intelligence, I’m always amazed by those who provide all kinds of supporting packages for Python and R and whatever programming languages people are using. However, in order to make sure I really understand how this machine thinking works, … Continued
Good parameter initialization results in fast and reliable model/data convergence. Before Origin 2017, you can write lengthy LabTalk functions or Origin C functions to intialize parameter values based on your data but it is still not easy for new users. Origin … Continued
The Enzyme Kinetics App is designed for performing enzyme kinetics analysis in two steps: Properly organize the data. Fit the data with proper models. Prior to performing the fitting process using the Enzyme Kinetics App, the data should be well-organized. When … Continued
Introduction For Origin 2017, a Principal Component Analysis for Spectroscopy App is available. The App is specifically designed to perform principal component analysis for spectra (IR, Fluorescence, UV-Vis, Raman, etc.). In chemometric analysis, researchers want to know which variables (frequency, wavelength or time) are important … Continued
Origin 2016 introduced a new way to perform batch processing when importing multiple data files into a workbook which is already setup with analysis, graphing, cell formatting, and etc. You can watch this video to see how it works. This blog … Continued
Introduction Occasionally users have the need to work with time data with hours that exceed 24. Some examples of this include: 30:45 => 30 hours, 45 minutes 60:15:30 => 60 hours, 15 minutes, 30 seconds For the purposes of this post, … Continued
Introduction Note: This post is an introduction to the LaTeX App. In a future blog posts, we will provide some insight, tips, and additional examples of using the App. With its release of Origin 2016, OriginLab has added a new … Continued
The Issue A question that comes up frequently is why Origin may not plot or fit a dose value of 0 (zero) for dose response curves (and those that are similar). It usually boils down to the following simple mathematical … Continued
