Key Techniques in Structural Biology, Their Strengths and Limitations

Structural biology uses a variety of techniques to determine the 3D structures of biomolecules such as proteins, nucleic acids and their complexes. In this article, we consider the key techniques, their role in structural biology, strengths and limitations.
The Wilcoxon Signed-Rank Test.

The Wilcoxon Signed-Rank Test

The Wilcoxon signed rank test, which is also known as the Wilcoxon signed rank sum test and the Wilcoxon matched pairs test, is a non-parametric statistical test used to compare two dependent samples (in other words, two groups consisting of data points that are matched or paired). In this article, we explain how and when this test should be used.

Understanding Structural Biology, Its Applications and Creating a Molecular Model

In this article, we consider what structural biology tells us and the techniques used to investigate it, the role of computation and how techniques can be used together to answer questions in a range of application areas.
The Kruskal Wallis Test

The Kruskal–Wallis Test

The Kruskal–Wallis test is a statistical test used to compare two or more groups for a continuous or discrete variable. It is a non-parametric test, meaning that it assumes no particular distribution of your data and is analogous to the one-way analysis of variance (ANOVA). The Kruskal–Wallis test is sometimes referred to as the one-way ANOVA on ranks, or the Kruskal–Wallis one-way ANOVA.
