Better support of doing fitting or peak analysis (including related gadgets) on Y offset plot. 

Better support of doing fitting or peak analysis on Y offset plot

In the past, if user plot stacked lines with Y offset and then do fitting, the fitted curves are not stacked and stay with original plot.

Improved in Origin 2019b.

Improve Statistics results for some special NLFit types

Improve Statistics results for some special NLFit types

For Nonlinear Multiple Dependent Variables Fitting, ANOVA table is improved.

Before 2019b, ANOVA table in the report only shows the results for the first dataset(Dataset B in the following case). Now the result is improved and similar to Global Fit's result, DF and TSS should be total data.

For the Nonlinear Fitting using Orthogonal Distance Regression, R-Square quantity is improved.

Before 2019b, R-Squared value may always be 1 though the ODR fit is normal. It is caused by the inappropriate TSS. Now the R-Square should be more accurate as TSS calculation is improved as:

TSS = sum( (y - ymean)^2) + sum( (x - xmean)^2)
R^2 = 1 - RSS/TSS
where TSS is the total sum of square, and RSS is the residual sum of square.

Gel Molecular Weight Analyzer

Determine gel molecular weight from electrophoresis.

Download Gel Molecular Weight Analyzer app from the page and install the app.

This app fits a standard curve to relate the known molecular weights of proteins in a set of standards (y-axis) to their relative migration (x-axis), and estimates molecular weights of unknow proteins. 

Features include:

• Define a lane of standard sample image

• Detect bands and mark their positions or mark them manually

• Fit a standard curve from the standard sample

• Calculate molecular weight of unknown sample by the regression equation

Fit ODE

Fit ordinary differential equation.

Download Fit ODE app from the page and install the app.

This app is capable of fitting ordinary differential equation.

Speedy Fit

Download Speedy Fit app from the page and install the app.

This app can be used to fit a large number of datasets from a worksheet sequentially and speedily, and create a simple report table of parameter values and fit statistics.

Features include:

• Fit all XY (YErr) datasets in the active worksheet

• Perform linear, polynomial and nonlinear fit using different algorithms

• Preview of fitted curve for current dataset with 95% confidence band and 95% prediction band

• Select a built-in or user-defined function for nonlinear fit

• Three choices for parameter initialization for nonlinear fit:

  • Initialize each dataset independently

  • Use fit values from previous dataset as initial parameter values for next dataset

  • Use custom (user-specified) initial parameter values for all datasets

• Output parameter values, standard errors, dependencies etc and also output fit statistics including fit status

• Output the fitted curve, and allow go through each dataset by the navigation buttons on the fitted curve graph

• Use metadata elements such as long name or comments as dataset identifier in the output sheet

Adjust height of worksheet label row for output columns

Adjust height of worksheet label row for output columns

After analysis is done, there are long column comments long names in output columns.

In the past, we auto resized the column width to fit such info. 

In Origin 2019b, by default we adjust height of column label row to avoid very wide output columns.

Use @RCW=1 to rollback the old behavior.

2D Correlation Spectroscopy Analysis

Calculate synchronous and asynchronous correlation spectra.

Download 2D Correlation Spectroscopy Analysis app from the page and install the app.

This app calculates synchronous and asynchronous correlation spectra from one set of dynamic spectra (homo correlation) or two sets of dynamic spectra (hetero correlation) induced by perturbation.
