Detailed Description

mutable sequence handle.

Sequences are mostly used as part of a multiple sequence alignment. The class allows for fast mapping between residue index and position in the sequence. The GetResidueIndex() method maps from position in the sequence to residue index, taking the sequence offset into account. The reverse mapping is done with GetPos().

Optionally, an entity view may be attached to the sequence with AttachView(). If HasAttachedView() is true, the GetResidue() method can be used directly to map from sequence position to residue. Note that it is required that the entity view has only one chain. Sequences are created from string as

String seq_str="ALGW--ALN"

SequenceHandle seq=CreateSequence("NAME", seq_str);

Sequences IO is dealt with in the sequence module. For more information, consult this page.

SequenceHandle ( const impl::SequenceImplPtr & impl )

Member Function Documentation

void AttachView ( const mol::EntityView & view )

attach entity view to sequence

Exceptions:

IntegrityError when the view contains more than one chain

void AttachView	(	const mol::EntityView &	view,
		const String &	chain_name
	)

attach entity view to sequence

The sequence is mapped onto the chain with given name

Definition at line 267 of file sequence_handle.hh.

SequenceHandle Copy ( ) const

create copy sequence The newly created sequence has the same attached view.

iterator end ( ) const

inline

Definition at line 268 of file sequence_handle.hh.

mol::EntityView GetAttachedView ( ) const

get attached view. may be an invalid entity view

See also:: SequenceHandle::AttachView(const mol::EntityView&, const String&)

int GetFirstNonGap ( ) const

Get position of first non-gap character in sequence.

String GetGaplessString ( ) const

Get sequence as string ignoring gaps.

int GetLastNonGap ( ) const

Get position of last non-gap character in sequence.

int GetLength ( ) const

Get lenght of sequence, including gaps.

const String& GetName ( ) const

Get name of sequence.

See also:: SequenceHandle::GetName()

int GetOffset ( ) const

Get sequence offset from N-terminus.

See also:: SequenceHandle::GetOffset

char GetOneLetterCode ( int position ) const

get one letter code of residue at position

int GetPos ( int residue_index ) const

Get zero-based index for given residue number.

Exceptions:

out_of_range,if number is not included in sequence.

mol::ResidueView GetResidue ( int position ) const

get residue at position

will return the residue view at the given sequence position or an invalid residue view when no view is attached, the index is out of bounds or the position contains a gap.

int GetResidueIndex ( int pos ) const

Get residue index corresponding to given sequence position.

Parameters:

pos	zero-based index

Exceptions:

out_of_range if pos is not in [0, length-1].

const String& GetString ( ) const

get sequence as a string, including all the gaps

See also:: GetGaplessString()

GenericPropContainerImpl* GpImpl ( )

const GenericPropContainerImpl* GpImpl ( ) const

bool HasAttachedView ( ) const

whether the sequence has an attached view

See also:: SequenceHandle::AttachView(const mol::EntityView&, const String&)

impl::SequenceImplPtr& Impl ( ) const

bool IsValid ( ) const

whether the sequence is valid

operator ConstSequenceHandle ( ) const

bool operator!= ( const SequenceHandle & rhs ) const

bool operator== ( const SequenceHandle & rhs ) const

char operator[] ( size_t index ) const

void SetName ( const String & name )

set name of sequence

void SetOffset ( int offset )

Set sequence offset.

By default the sequence offset is zero, i.e. the beginning of the sequence lies exactly at the N-terminus. Setting the sequence offset to a positive number will shift the sequence towards the C-terminus.

void SetOneLetterCode	(	int	position,
		char	new_char
	)

void SetString ( const String & seq )

Set sequence String.
