TNT, A General Purpose Least Square Refinement for Macro-Molecular X-Ray Crystallography

Description:

This package is a complete suite of computer programs for optimizing the fit of macromolecular models to x-ray crystallographic data. The parameters of the atomic model can be restrained to structure factors and the principles of stereochemistry. The programs are very general and can be used for any macromolecular problem. A model can be restrained by other forms of data without modification to the code.

The programs all operate in a similar fashion, reading free-format input using a common set of keywords. All Fourier transforms are calculated with space-group specific FFT's resulting in very fast execution times.
