Make/O/N=100 GDataX, GDataY, GOutput // waves for data Igor Pro can perform the operation of finding the line or curve that minimizes ( chi2 ). The following code generates a gaussian, then fits it with Genetic Optimisation: (extra questions will be answered here if/when they are asked)Įnter the following code in the procedure window (Ctrl-J) to create a user-defined Gaussian Fit Function: Refer to the XOP help file as a first port of call.

I did a linear fit and I know that ln (f (x))x is the function for semi-log and ln (f (x))ln (x) is for log-log, I just dont know how to apply these to fit the curve log-log and semi-log linearization. (to load this at IGOR startup place a shortcut to the ipf file in the IGOR procedures folder) Igor Pro allows you to specify minimum and maximum values for each fit coefficient or for linear Curve Fit Dialog Screen Shot with Constraints Highlighted. I dont know how to use the curve fitting on Igor pro with log-log linearization and semi-log linearization. Access the GUI by selecting Motofit->Genetic Curvefitting. If you wish to use the curvefitting GUI then load the geneticoptimisation.ipf procedure file.exponential function to the decaying phases of Kv4.3 currents by Igor Pro 5.02 (Wave. Make an alias (Macintosh) or shortcut (Windo ws) for your Igor64 application file and put the alias or shortcut on your desktop. obtained by fitting to curve with a double exponential function.

Using the equation you found in 3), find the half-life of Polonium. Simulation results were analyzed using Igor Pro and Python. All tools are for Igor Pro (which currently has version 9.00. The LOGEST function in Excel is a function used to fit an exponential curve to exponential data. Both Windows and Mac Universal binaries are available. Decay kinetics were analyzed by fitting a bi-exponential function to the EPSC decay time. To get started: Enter or paste in your data.
