Motofit

Motofit is a powerful 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. Motofit provides robust and fast optimisation, with a choice between Genetic Optimization (Differential Evolution) and Levenberg-Marquardt.

The aim is to provide maximal functionality, with easiest interaction. Limit the time between collection and publication.

The main Motofit page is located at http://motofit.sourceforge.net/, although the most up to date Beta code can be downloaded below.

Please note that Beta Motofit may not be immediately back compatible with preexisting pxp files. As such one should have a backup of the pxp file before you start to use these versions. Once you open the preexisting file select the menu option “motofit->Transfer data from old version to new version” to use a preexisting file.

If you need to reduce Platypus data please install one of the Motofit versions above, then use one of the two files below to install the code required for Platypus reduction.


Platypus installer for windows

Platypus installer for OS X


Please note that you need to have IGOR Pro installed on your computer to use these. You do not need the full version, the free demo version is also sufficient.
