Inarecentmanuscript[21],weintroducedaphysicalmodel to describe the ﬂuctuating conformational dynamics of IDPs. The motivation for the new computational model for IDPs stems in part from the fact that commonly used molecula I can tell you from experience that Rosetta's scorefunction wants to make things relatively stuck together even in the absence of an explicit radius of gyration term. FloppyTail's lowest scoring models will tend to have any flexible regions stuck together or stuck against larger protein bodies; it's rare for the best models to have much protein. The statistical analysis of radii of gyration for 3413 protein structures from four general structural classes (all-α, all-β, α/β, α+β) demonstrates that each class of proteins has its own class-specific radius of gyration, which determines the shape of protein structures: α-proteins have the largest radius of gyration while α/β. relating the mean square end-to-end distance of a random flight polymer to the number of formula units in a statistical segment.

To analyze structural changes of a protein, you can calculate the radius of gyration or the minimum residue distances over time (see sec. Radius of gyration and distances), or calculate the RMSD (sec. Root mean square deviations in structure) The RMSD reaches to the platue after 3500 ps, and the value is about 0.12 nm, which means the equilibrium structure of the protein is not far from the initial structure. The radius of gyration of the protein was also extracted to see how compact the protein was during 5000 ps simulation. This measure was reported in Fig 3 Radius of gyration A relation of the area or mass of a figure to its moment of inertia.

This increment of the gyration radius is close to the values I calculated, 9.6% for trajectory A and 7.4% for trajectory B Let us, for example, compute the radius of gyration and the RMSD for a protein with trajectories saved in Path in SAMSON. To use the functionality of MDAnalysis, we need to export trajectories we would like to analyze from SAMSON into a format supported by MDAnalysis (e.g., XYZ format). These trajectory files are then provided to MDAnalysis.
