Fit TabFit theoretical functions to your data, such as a line, exponential, polynomial, or Gaussian function. This tab utilizes Igor Pro’s pre-exising Curve Fitting algorithm FuncFit, and is similar to Igor Pro’s Curve Fitting panel (Igor Menu > Analysis > Curve Fitting...), but works within the framework of NeuroMatic. Function – select a function to fit your data. The Fit Results Table will appear, containing the following fit function waves:
FT_coef – contains the coefficient result values. FT_sigma – contains the coefficient sigma (error) values. FT_guess – contains the coefficient initial guess values (optional). FT_hold – contains the hold coefficient parameter (enter 1 to hold a particular coefficient at its initial guess). Range – set the range over which to perform the curve fit. To fit between cursors, place Igor Pro’s cursors A and B on the active wave in the Channel Display Graph and check Cursors true, as displayed above. Fit Waves – final fits are displayed on top of your data in the active Channel Display Graph. Control their appearance here.
Points – enter the number of points of the final fit wave. Save – check true if you wish to save the final fits. Waves will be saved in the current directory with the prefix name “fit_”. Compute – compute the fit wave based on initial coefficient guesses. Plot – plot all fit waves. Execute – compute the curve fit. Results can be saved to a table.
Fit All – compute the fit of all currently selected waves, saving values to a table. Save – save current fit results to an output table. Plot All – plot all data and fit waves. Clear – clear current fit results from the output table. Clear All – clear all output table values. Auto Fit – check true to automatically compute the curve fit when incrementing through your data waves. Stdv Weighting – check true to compute weighted fits. Standard deviation values must reside in waves with the same name of the waves to be fit, but with “Stdv_” or “InvStdv_” as the prefix. Print Results – print results to Igor Pro’s history window. max iter – maximum number of fitting iterations. |
