A feature is a measurement of a molecular structure that is represented geometrically. Examples include the properties measured by components of Rosetta's ScoreFunctions such as torsion angles, hydrogen bond distances and angles. More complicated examples include the volume of voids or radial density distributions.
Exploring features in experimental and predicted structures usually involves common steps:
Going through these steps by hand is often not too hard. Usually, however, the context and purpose of the investigation evolves. So over time, the analysis needs to be re-done with new datasets, using different features and generating different plots and statistics. If the original analysis was not well organized, each time it will be as hard as the first.
The Features Scientific Benchmark is designed to help you investigate features to make re-analysis easy and straight forward. It provides,
