You can examine the Motofit manual on the wiki. Motofit has been benchmarked against other reflectometry software, to investigate it's accuracy. "Co-refinement of multiple contrast neutron / X-ray reflectivity data using MOTOFIT." Journal of Applied Crystallography 39: 273-276. This is so I can justify spending the time writing it to my bosses. If you use Motofit to analyse reflectometry data, please cite Motofit in the references. Jump straight from collection to publication: no messy, timewasting replotting via Excel. Graphical examples of the Motofit program.Īll graphical output is fully customisable, and publication quality.
#IGOR PRO 7 VS 6 MANUALS#
You can download all the Motofit software, and manuals from the sourceforge website.Ī list of publications that have used the Motofit program to analyse data.
Please note that the Motofit package now installs Gencurvefit.xop and Abeles.xop when you use the Win32/Mac installer programs It is designed to complement and follow the same syntax as IGOR's curvefit operation. It is a pre-compiled plugin, which allows anyone to use genetic optimisation to fit any user-defined fitfunction. lsGex - this file fits a generalised distribution of exponentials to dynamic light scattering data.The coefficient files used in Motofit will not work in Motofit_imag. Unfortunately solvent penetration is not available in this version. Motofit_imag - this version uses imaginary scattering length densities, to account for absorption effects.Motofit - this is when you want to parametrise solvent (subphase) penetration in your layers.
#IGOR PRO 7 VS 6 LICENSE#
Motofit isn't a black box, you find something you don't like, you can change it (within the license conditions) Batch fitting of multiple datasets, e.g.Fits as many layers as you like (or can fit on the screen).Analytic scattering length density profiles (user specified functional form).Simultaneous co-refinement of multiple contrast datasets, with arbitrary linkages.Estimation of layer thicknesses from fringe spacing.Estimation of layer thicknesses from Fourier transform of datasets.Fitting with complex interparameter constraints.Provides a graphical interface to assist fitting.Publication quality graphs, with no further manipulation required.Absorption effects through imaginary scattering length density.Fit to normalised Fresnel Reflectivities.Fitting as log R vs Q, RQ4 vs Q and R vs Q.Point by point Resolution smearing, roughness (Nevot+Croce) and background included.Genetic Algorithm or Levenberg-Marquardt for minimisation.Easy co-refinement of multiple contrast reflectometry data (X-rays and neutrons).Fits neutron and X-ray reflectivity data using Parratt recursion or Abeles matrix.The development of the Motofit package has been sponsored by the Australian Nuclear Science and Technology Organisation ( ANSTO).
#IGOR PRO 7 VS 6 FULL#
Motofit will work just as well in the demo version, as the full version. You don't need to purchase IGOR in order to use the functions, a free demo version is available from their website. It works within the analysis package IGOR Pro ( Wavemetrics, OR). Motofit is licensed using the GNU General Public Licence. Limit the time between collection and publication. The aim is to provide maximal functionality, with easiest interaction.
Motofit provides robust and fast optimisation, with a choice between Genetic Optimization ( Differential Evolution) and Levenberg-Marquardt. Motofit is a package that aids the simultaneous least squares fitting of multiple-contrast specular X-ray and neutron reflectivity data, using an Abeles Matrix formalism or Parratts recursion formula.
