Structure: Structure Ensembles
This popup allows the user to import, export and view information about individual structures and structure ensembles in the project. Structure ensembles can be split into separate models and individual structures can be merged into ensembles. In addition, RMSDs can be calculated within a superimposed ensemble and displayed on the structure using a colour code and the Structure: Structure Viewer popup.
Viewer
Opens the the Structure: Structure Viewer popup for inspection of the structure.
Ensembles
The {Ensembles} tab lists the current structure ensembles and individual structures in the selected molecular system. Various options are available to edit, import and export structures. Structure ensembles can be split, and individual structure can be merged into ensembles.
The Structure: Structure Ensembles popup (Ensembles).
Molecular System
Specifies the molecular system for which the structure ensembles are listed in the Ensembles table.
Ensembles table
This table contains all the structure ensembles and individual structures in selected molecular system.
#
The ensemble serial number.
Chains
The chains that are present in the structure ensemble.
Residues
The number of residues per structure in the ensemble.
Models
The number of models in the ensemble.
Generation Run
The structure generation run of the ensemble.
Violation Lists
The number of structure violation lists for the ensemble.
Atom Name System
The atom naming system used in the structure ensemble.
Residue Name System
The residue naming system used in the structure ensemble.
Show Coords
Opens the {Coords} tab to display the coordinates of the atoms in the structure ensemble.
Import
Allows the user to import a structure or structure ensemble using the Import PDB file popup.
Export
Allows the user to export a structure or structure ensemble using the Export PDB file popup.
Remove
Removes the selected structures or structure ensembles from the molecular system.
Merge Into Ensemble
Merges a selection of multiple structures into a structure ensemble. The structures have to contain the same atoms.
Split Models
Splits a structure ensemble that consists of multiple models into the individual models.
Align Coords
Aligns the coordinates of the structure ensemble using a best fit routine.
Residues
The {Residues} tab lists the residues in the selected molecular system and some of their structural properties. Various sources of information can be toggled on and off for display in the Residues table.
The Structure: Structure Ensembles popup (Residues).
Ensemble
Specifies the ensemble for which residues and properties are displayed.
CcpCode
Specifies the CcpCode to display parameters only for specific residue types.
Angles
If selected, shows angle information in the Residue table, e.g. phi and psi angles in proteins. In case of a structure ensemble, averages of the ensemble are listed.
RMSDs
If selected, shows the RMSDs in the Residue table, e.g. backbone and all atom RMSDs.
Rama. params
If selected, shows the Ramachandran parameters in the Residue table.
Validation results
If selected, shows a variety of RMSDs calculated for individual atoms in the Residue table.
Residues table
This is the table that lists all the residues and their properties.
Chain
The name of the chain.
Seq Code
The sequence code of the residue.
Ccp Code
The Ccp Code of the residue.
Backbone RMSD
The backbone RMSD value for the residue. This value can be calculated in an ensemble using the [Calculate RMSDs] button.
All atom RMSD
The backbone RMSD value for the residue. This value can be calculated in an ensemble using the [Calculate RMSDs] button.
Φ Angle
The phi angle for a residue in a protein chain.
Ψ Angle
The psi angle for a residue in a protein chain.
Rama. Region
The classification of the residue in the Ramachandran plot region.
Calculate RMSDs
Calculates the RMSDs for the selected ensemble.
View Residue
Labels and focusses on the selected residue in the Structure: Structure Viewer popup.
Display Params
This option applies a colour code and adapts the sizes of atoms for the residues in the Structure: Structure Viewer popup. The colours and sizes of atoms depend on the value of the parameter selected under Validation Parameter (see below). Small atoms and blue colour correspond to small values of the parameter; Large atoms and yellow colours correspond to larger values of the parameter.
Delete Params
Deletes the parameters selected under Validation Parameter (see below).
Validation Parameter
Specifies the parameter that is used for the [Display Params] and [Delete Params] buttons.
Coords
The {Coords} tab lists the atom coordinates for a selected structure model.
The Structure: Structure Ensembles popup (Coords).
Ensemble
Specifies the ensemble from which models are selected for display of coordinates.
Model
Specifies the model in the selected ensemble for which coordinates are displayed.
Coords table
This table lists all the atomic coordinates in the selected model.

Residue
The residue name.
Chain
The chain name.
SeqId
The sequence identifier
x
The x coordinate of the given atom.
y
The y coordinate of the given atom.
z
The z coordinate of the given atom.
Occupancy
The occupancy of the given atom.
B Factor
The B factor of the given atom.
Locn Code
