Filters a structure based on detected stereo-chemical violations. Entity version.

If a stereo-chemical violation (i.e., a bond or an angle with a value outside the range defined by the mean value, the standard deviation and the tolerance parameter) is detected in a residue's side-chain, all atoms in the side chain are removed from the structure. If a violation is detected in the backbone, all atoms in the residue are removed. This behavior is changed by the always_remove_bb flag: when the flag is set to true all atoms in the residue are removed even if a violation is just detected in the side-chain

If a stereo-chemical violation (i.e., a bond or an angle with a value outside the range defined by the mean value, the standard deviation and the tolerance parameter) is detected in a residue's side-chain, all atoms in the side chain are removed from the structure. If a violation is detected in the backbone, all atoms in the residue are removed. This behavior is changed by the always_remove_bb flag: when the flag is set to true all atoms in the residue are removed even if a violation is just detected in the side-chain

int  sequence_separation,
Real  max_dist 
)

Creates a list of distances to check during a Local Difference Distance Test starting from multiple reference structures.

Requires a list of reference structure and an inclusion radius (max_dist).

The structures in the list have to be properly prepared before being passed to the function. Corresponding residues in the structures must have the same residue number, the same chain name, etc. Gaps are allowed and automatically dealt with: if information about a distance is present in at least one of the structures, it will be considered.

If a distance between two atoms is shorter than the inclusion radius in all structures in which the two atoms are present, it is included in the list. However, if the distance is longer than the inclusion radius in at least one of the structures, it is not be considered a local interaction and is excluded from the list

The function takes care of residues with ambigous symmetric sidechains. To decide which naming convention to use, the functions computes a local distance score of each reference structure with the first reference structure in the list, using only non ambigously-named atoms. It picks then the naming convention that gives the highest score, guaranteeing that all references are processed with the correct atom names.

The cutoff list that will later be used to compute the Local Distance Difference Test score and the sequence separation parameter must be passed to the function. These parameters do not influence the output distance list, which always includes all distances within the provided max_dist (to make it consistent with the single-reference corresponding function). However, the parameters are used when dealing with the naming convention of residues with ambiguous nomenclature.

)

Calculates the Distance RMSD in a model, given a list of distances with their refence length.

Calculates the two values needed to determine the Distance RMSD Test score for a given model, i.e. the sum of the squared distance deviations and the total number of distances on which the sum was calculated. The function requires a list of distances for which the distance deviation has to be computed, together with a reference length for each of them. The function also requires a model on which the returned values are computed. Furthermore, the function requires a default deviation value to be used in the calculations when a distance is not present in the model.

The distance information needs to be stored in ian instance of the GlobalRDMap object. This object stores two distance lengths for each distance. This function uses the first of them as reference length and ignores the second.

The function only processes standard residues in the first chains of the model and of the reference For residues with symmetric sidechains (GLU, ASP, ARG, VAL, PHE, TYR), the naming of the atoms is ambigous. For these residues, the function computes the Distance RMSD score that each naming convention would generate when considering all non-ambigous surrounding atoms. The solution that gives lower score is then picked to compute the final Distance RMSD score for the whole model.

A sequence separation parameter can be passed to the function. If this happens, only distances between residues whose separation is higher than the provided parameter are considered when computing the score.

If a string is provided as an argument to the function, residue-per-residue statistics are stored as residue properties. Specifically, the local residue-based Distance RMSD score is stored in a float property as the provided string, while the residue-based sum of squared distances and the number of distances checked are saved in two properties named [string]_sum (a float property) and [string]_count (an int property).

create a density representation of an entity in a density map

This function creates a density representation of the entity provided by the user in a density map, also provided by the user. The user can choose the type of density of the output map:

Journal of Molecular Biology (2009) pp. 1-10 ROSETTA_LOW_RESOLUTION guassian spheres in real space to represent density, one per residue. See reference above. Only useful at low resolution

The user can also choose if the density map should be cleared of its previous content before creating the density representation.

The user must also provide a resolution parameter.

This function will only create a density represenation of the entities (or portion of entities ) that fall within the borders of the map. The user must take care that this condition is verified for all entities for which he wants a representation.

This functions creates a density representation of the entity provided by the user in a density map, in Fourier space using the correct scattering factors for the elements involved.

The user can also choose if the density map should be cleared of its previous content before creating the density representation.

The density is generated in Fourier space. In order to avoid artifacts in the final density representation, the function avoids sharp frequency cutoffs by applying a Gaussian falloff. The user must provide the resolutions at which the cutoff should begin and end, as opposed to a single resolution cutoff value.

This function will only create a density represenation of the entities (or portion of entities ) that fall within the borders of the map. The user must take care that this condition is verified for all entities for which he wants a representation.

Calculates the Local Distance Difference Test score for a given model starting from an alignment between a reference structure and the model.

Calculates the Local Distance Difference Test score given an alignment between a model and a taget structure. Requires a threshold on which to calculate the score and an inclusion radius to determine the interatiomic distances to check. Obviously, the strucvtures of the model and the reference must be attached to the alignment. By default the first structure in the alignment is considered the reference and the second is considered the model, but this can be changed by passing to the function the indexes of the two structures in the ref_index and mdl_index parameters. BEWARE: This algorithm uses the old version of the Local Distance Difference Test (multiple cycles, single threshold, etc. ) and will give a slightly different result than the other functions
