## ◆ centerTransform()

## ◆ computeSecondaryStructure()

 bool SBMStructuralModel::computeSecondaryStructure ( bool & secondaryStructureChanged, bool forceUpdate = false )

The function returns true if and only if everything went well. The boolean secondaryStructureChanged is modified by the function and is true if and only if the secondary structure was changed compared to the previous call. Since several objects may call this function, a SecondaryStructureChanged event is also sent when this is the case, so that all objects may be warned.

 double SBMStructuralModel::getAsphericity ( const SBNodeIndexer & nodeIndexer )
static

This function returns the asphericity parameter of the system of atoms (based on their positions and masses) in nodeIndexer. The asphericity parameter changes in the [0, 1] range, where 0 corresponds to a sphere and 1 corresponds to a rod.

## ◆ getLockedFlag()

 bool SBMStructuralModel::getLockedFlag ( ) const
virtual

This function returns the locked flag of the structural model. When the structural model is locked, its geometry (the atoms positions), topology (the bonds) and identities (node names and indices) cannot be edited by the user. However, other properties can still be edited. For example, secondary structure information can still be computed, and materials and color schemes can still be applied. Note that some properties that cannot be edited by users can still be edited by developers.

## ◆ getPrincipalAxes()

 SBMatrix33 SBMStructuralModel::getPrincipalAxes ( const SBNodeIndexer & nodeIndexer )
static

Returns the principal axes of the inertia tensor of the system of atoms (based on their positions and masses) in nodeIndexer. The eigen vectors are sorted by their eigen value in the descending order, i.e. the first one corresponds to the first principal axes. In other words: the first axis corresponds to the longest domain dimension, while the third axis corresponds to the smallest domain dimension.

If the nodeIndexer doesn't contain any atoms or their parents then the function returns a zero matrix.

 SBQuantity::length SBMStructuralModel::getRadiusOfGyration ( const SBNodeIndexer & nodeIndexer )
static

This function returns the radius of gyration of the system of atoms (based on their positions and masses) from nodeIndexer. The radius of gyration is computed as follows: Rg = sqrt(sum(m_i * (r_i - r_c)^2, i=1..N) / M) where N is the number of atoms, m_i is the mass of i-th atom, r_i is the i-th atom's position, r_c is the center of mass of all N atoms, M is the total mass of all of the N atoms.

If the nodeIndexer doesn't contain any atoms or their parents then the function returns zero.

## ◆ getShapeParameter()

 double SBMStructuralModel::getShapeParameter ( const SBNodeIndexer & nodeIndexer )
static

This function returns the shape parameter of the system of atoms (based on their positions and masses) in nodeIndexer. The shape parameter, S, changes in the [-0.25, 2] range, where 0 corresponds to a sphere, negative values correspond to oblate ellipsoid, possitive values correspond to prolate ellipsoid.

It is computed as follows: S = prod((lambda_i - lambda_mean), i=1..3) / (lambda_mean^3) where lambda_i is the i-th eigen value of the inertia tensor, lambda_mean is the mean of eigen values and is equal to sum(lambda_i, i=1..3).

## ◆ getSpatialTransform()

 SBDTypeSpatialTransform SBMStructuralModel::getSpatialTransform ( const SBNodeIndexer & nodeIndexer )
static

Returns the spatial transform based on the inertia tensor of the system of atoms (based on their positions and masses) in nodeIndexer.

If the nodeIndexer doesn't contain any atoms or their parents then the function returns a zero transform.

## ◆ getStructuralRoot()

 SBMStructuralModelNodeRoot * SBMStructuralModel::getStructuralRoot ( ) const

This function returns a pointer to the structural root of the structural model. This root is a structural node, and can be used as a convenience root for e.g. recursive algorithms that operate on structural nodes (such algorithms could not work on the structural model itself, since the SBMStructuralModel class does not derive from SBMStructuralModelNode).

This function returns true if all atoms in nodeIndexer are in the same plane Note that for 3 atoms and less it will always return true

## ◆ populateChainIDs()

 bool SBMStructuralModel::populateChainIDs ( bool forceRenumbering = false )

This function populates the chain IDs for all chains in the structural model.

The numbering of chain IDs for the chains with missing IDs will start from the maximum chain ID present in the structural model, for example, if there are chains with IDs 0, 1, 4 then the numbering of other chains with missing IDs will commence from 5.

If some chains have the same IDs then the repetitions will be renumbered, for example, chain IDs 0, 2, 2 will become 0, 2, 3.

If forceRenumbering is set to true then it renumbers chains IDs starting from 0 iff at least on of the chains has a missing ID or has the same ID as another chain in the structural model.
