Member Function Documentation

std::pair<geom::Line3, Real> FitCylinder ( std::vector< unsigned long > &  indices_ca) const

Returns a line which is the axis of a fitted cylinder to the atoms with indices given in indices_ca It is assumed that we fit an alpha-helix and that the CA atoms are oredered sequentially This is used for the initial guess of the helix axis

std::pair<geom::Line3, Real> FitCylinder ( const mol::EntityView view1) const

see FitCylinder(std::vector<unsigned long>&)

Real GetAlphaHelixContent ( std::vector< unsigned long > &  indices_ca,
std::vector< unsigned long > &  indices_c,
std::vector< unsigned long > &  indices_o,
std::vector< unsigned long > &  indices_n 
) const

Returns the percentage of residues in the EntityView (segment) that are in an alpha-helix Each residue is assigned as being in an alpha-helix or not, based on and backbone torsion angles and the hydrogen bonding (O-N) (this term is used only if the segment contains at least 8 residues The entity view should be a single segment with no gaps and no missing N,CA,C,O backbone atoms the first and last residues will not be asessed for helicity

Real GetAlphaHelixContent ( const mol::EntityView segment) const

see above

Real GetAngle ( const AtomHandle a1,
const AtomHandle a2,
const AtomHandle a3 
) const

Returns the angle between the three atoms in rad

a2 is considered the central atom, i.e the result is the angle between the vectors (a1.pos-a2.pos) and (a3.pos-a2.pos)

Real GetAngle ( int  atom1_index,
int  atom2_index,
int  atom3_index 
) const

Returns the angle between the three atom indices in rad

atom2 is considered the central atom, i.e the result is the angle between the vectors (atom1.pos-atom2.pos) and (atom3.pos-atom2.pos)

geom::Vec3 GetCenterOfMassPos ( std::vector< unsigned long > &  indices,
std::vector< Real > &  masses 
) const

Calculates the center of mass given a list of indices and provided masses.

the masses vector contains only the masses for the atoms indexed by indices, not for all atoms in the frame

Real GetDihedralAngle ( const AtomHandle a1,

Returns the minimal distance between the center of mass of two groups of atoms

atoms and their masses are defined by indices and masses for those atoms

Real GetMinDistBetwCenterOfMassAndView ( const mol::EntityView view_cm,
