Manual parameter fitting: see the tutorial and the FAQ

Automatic parameter fitting

Version 0.9.1 beta of the lsfitpar program for robust fitting of bonded parameters is available under the Affero GPL. The two most straightforward ways to obtain it are:

In both cases, this yields (among other things) a README file with further instructions. Also included in the repository is an examples subdirectory containing a tutorial that guides the reader through the practical aspects of bonded parameter fitting and the different features of the lsfitpar program, and a scripts subdirectory with handy helper scripts (the tutorial explains their usage). We hope this material will be helpful to your research, and appreciate feedback; see the e-mail link in the page header.
