Single crystal structure refinement software
There are currently several software packages available, which all aim for the same goal: Making computer-aided structure refinement simple and effective.
Thus the simple and highly-developed small-molecule single-crystal refinement programs have much in common with the more complex protein single-crystal and ...
For crystallographic data, this refinement process is usually done in reciprocal space. Using a least-squares or maximum-likelihood target, the model parameters ...
Section 4.7.2. Rietveld versus single-crystal refinements
In contrast, a single-crystal refinement only fits the first set of parameters, the structural parameters. The other three categories of parameters add ...
