Detailed Description

base class for entity editors

Entities, chains, residues and atoms are assembled and modified via editors. Editors are usually used as one of the concrete subclasses of EditorBase: XCSEditor and ICSEditor. The former operates on the external carthesian coordinate system while the latter operates on the internal coordinate system. To create a new editor, use EntityHandle::EditXCS() and EntityHandle::EditICS(), respectively.

For an introduction to the concept of editors go here

void AddAltAtomPos	(	const String &	group,
		const AtomHandle &	atom,
		const geom::Vec3 &	position,
		Real	occ = 1.0,
		Real	b_factor = 0.0
	)

Add alternative atom position.

Parameters:

group	is the name of the alternative atom position group. If no group of that name exists, it will be created.
atom	is the atom handle the additional location belongs to. It is required that the atom has been inserted via InsertAltAtom, If the atom is a conventional atom without alternative location, a Error will be thrown.
position	is the alternative position

TorsionHandle AddTorsion	(	const String &	name,
		const AtomHandle &	a1,
		const AtomHandle &	a2,
		const AtomHandle &	a3,
		const AtomHandle &	a4
	)

Add named torsion to entity.

BondHandle Connect	(	const AtomHandle &	first,
		const AtomHandle &	second
	)

connect two atoms with bond

If there is already a bond between the two atoms, no new bond is created. Instead, the already existing bond is returned.

void DeleteAllAtoms

(

ResidueHandle

res

)

Delete all atoms of residue.

All associated torsions and bonds will also be removed

void DeleteAtom

(

const AtomHandle &

atom

)

Delete specific atom from this residue.

All associated torsions and bonds will also be removed as well.

Parameters:

atom	is the atom to remove. If no such atom exists, this method will have no effect

void DeleteChain

(

const ChainHandle &

chain

)

delete chain

all associated atoms, residues, torsions and bonds will also be deleted.

void DeleteResidue

(

const ResidueHandle &

residue_handle

)

Delete residue.

Atoms, bonds and torsions involving this residue are removed as well

ChainHandle::DeleteResidue, DeleteAtom

AtomHandle InsertAltAtom	(	ResidueHandle	residue,
		const String &	name,
		const String &	alt_group,
		const geom::Vec3 &	pos,
		const String &	ele = "",
		Real	occ = 1.0,
		Real	b_factor = 0.0
	)

Insert new atom with alternative position indicator.

See also:

EditorBase::AddAltAtomPos(), ResidueHandle

AtomHandle InsertAtom	(	ResidueHandle	residue,
		const String &	name,
		const geom::Vec3 &	pos,
		const String &	ele = "",
		Real	occupancy = 1.0,
		Real	b_factor = 0.0,
		bool	is_hetatm = false
	)

Insert new atom.

Insert new atom and add it to residue. For atoms with alternative atom locations use ResidueHandle::InsertAltAtom().

Parameters:

residue	is the parent residue
name	is the atom name. While free to choose a name, it is adviced to properly name the residues according to IUPAC rules as several algorithms as well as most builders in the conop module rely on proper naming.
pos	is the position of the atom in global coordinates

ChainHandle InsertChain

(

const String &

chain_name

)

create new chain

create new chain and attach it to entity.

Parameters:

chain_name

The chain name. Can be an arbitrary String. However, if you intend to use the PDB export funtionality, the chain_name should be a single letter, preferably in the range A-Z.

Returns:

The newly created chain handle

ResidueHandle InsertResidueAfter	(	ChainHandle	chain,
		int	index,
		const ResNum &	num,
		const ResidueKey &	k
	)

insert residue into chain

This method is identical to InsertResidueBefore() but inserts the residue after the specified position

See also:

InsertResidueBefore

ResidueHandle InsertResidueBefore	(	ChainHandle	chain,
		int	index,
		const ResNum &	num,
		const ResidueKey &	k
	)

void RenameAtom	(	AtomHandle	atom,
		const String &	new_name
	)

change the name of the atom to the new name

void RenameChain	(	ChainHandle	chain,
		const String &	new_name
	)

void RenameResidue	(	ResidueHandle	res,
		const String &	new_name
	)

void RenumberAllResidues	(	int	start,
		bool	keep_spacing
	)

renumber residues of all chains

Parameters:

start	Residues of every chain will be renumbered, whereas the first residue gets the residue number start.
keep_spacing	If set to false, residues will continously be renumbered ongoing from start. Otherwise the spacings between the residues are kept.

void ReorderAllResidues

(

)

reorder residues of all chains based on their residue number

void ReorderResidues

(

const ChainHandle &

chain

)

reorder residues of given chain based on their residue number

void SetChainDescription	(	ChainHandle	chain,
		const String	desc
	)

Assign a description to a chain.

Parameters:

chain	chain to assign to
desc	description

void SetChainType	(	ChainHandle	chain,
		const ChainType	type
	)

Assign type of chain according to ChainType.

Parameters:

chain	chain to assign to
type	type of the chain

void SetResidueNumber	(	ResidueHandle	res,
		const ResNum &	num
	)
