SupraFit - An Open source Qt based fitting application to determine stability constants from titration experiments

Abstract

A novel application to determine stability constants from supramolecular titration experiments is presented. The focus lies on NMR titration and ITC experiments for pure 1:1 systems, as well as mixed 2:1/1:1, 1:1/1:2 and 2:1/1:1/1:2 systems. SupraFit provides global and local fitting and a global search tool. Statistical methods are implemented and can be applied to analyse the results of nonlinear regression. Monte Carlo simulations, combined with the percentile methods and F-Test approaches to calculate confidence intervals are supported. The implemented statistical approaches are illustrated and discussed on model functions. All methods are accessible through an intuitive user interface, providing charts for all (kind of) data produced. SupraFit is written in C++, using the Qt Toolkit for the Graphical User Interface (GUI) and the Eigen library for nonlinear regression and is released under the GNU Public License (GPL).

“…More details can be found in the source code documentation for the AbstractModel, AbstractTitrationModel and Michaelis-Menten-Model. [38] A shorty summary on how to implement new models is given at the GitHub repository at https://github.com/conradhuebler/SupraFit/tree/master/docs. Furthermore, work to bring scripted models to SupraFit has basically been done in the development version.…”
