Ligand RMSD: Ligand RMSD (right Y-axis) indicates how stable the ligand is with respect to the protein and its binding pocket. In the above plot, 'Lig fit Prot' shows the RMSD of a ligand when the protein-ligand complex is first aligned on the protein backbone of the reference and then the RMSD of the ligand heavy atoms is measured. 几个概念：rmsd vs rmsf vs rmsdist. RMSD是对原子总数求平均，RMSF是对单个原子时间求平均. RMSD表示的是分子结构变化的程度，而RMSF值表示的是分子中各个原子运动的自由程度. rmsd.

method A-1) You can write a straightforward yet tedious command script, such as: echo residue 1; rmsd #0:1 #1:1 echo residue 2; rmsd #0:2 #1:2 echo residue 3; rmsd #0:3 #1:3 etc. and use the 'source' or 'read' commands to execute it, or just FileOpen (it should have a .com or .cmd extension). The "Compute RMSD to input ligand geometries" feature calculates the heavy-atom RMSD of each docked pose to its corresponding input structure. Obviously, the RMSDs will be meaningful only if the input ligand structures are already positioned in the frame of the receptor active site.

You can still calculate RMSF over time by using e.g.

The simulation was set at 300 K as default temperature and 310 K, average human root mean square deviation (RMSD), root mean square fluctuation ( RMSF), [bfactor] Calculate atomic positional fluctuations squared and weight by perform an RMS fit to the average structure (best) or the first structure (see rmsd) prior 12 Nov 2018 The concept is similar as RMSF between two structures. switch the atom name and then calculate the RMSD again; Selected least RMSD of 18 Jul 2016 In this tutorial, we analyze the root-mean-square fluctuation (RMSF).

The "Compute RMSD to input ligand geometries" feature calculates the heavy-atom RMSD of each docked pose to its corresponding input structure. Obviously, the RMSDs will be meaningful only if the input ligand structures are already positioned in the frame of the receptor active site. List of (alternating) indices and RMSF values, as produced e.g. by load_rmsf(). printLegend: Boolean, which triggers plotting of the legend. rmsfUnit: Specifies, which unit the y-axis is given in. colours: Vector of colours used for plotting.

This module uses the fast QCP algorithm [Theobald2005] to calculate the root mean square distance (RMSD) between two coordinate sets (as implemented in MDAnalysis.lib.qcprot.CalcRMSDRotationalMatrix() ). 7.1.2. RMSF¶.

Previous message: [Chimera-users] plotting RMSD vs Residue number Next message: [Chimera-users] delphi in chimera Messages sorted by: The "rmsd" command does not superimpose structures, it just reports the RMSD in their current positions (i.e. if they are far apart, the RMSD will be high even if they are copies of the same structure). Ensemblematch is only a graphical tool and not a command, and it compute_quantiles: Compute quantiles for specified 'variable' grouping by 'ids' cross_validate_statistics: Evaluate a two sample tests between different classes of date_code: create date code of the form YYMMDD inputs: d (optional): estimate_primary_modes_1d: For each set of rows grouped by the columns in ids, binary find_modes_in_density: provides estimate_primary_mode_1d, which RMSF stands for root mean square fluctuation. This is a numerical measurement similar to RMSD, but instead of indicating positional differences between entire structures over time, RMSF is a calculation of individual residue flexibility, or how much a particular residue moves (fluctuates) during a simulation.
