Detailed Description

Minimalistic pdb parser.

Contain positions, atomic indexes, occupancy and beta. We should also add other info (e.g. residue name etc).

Member Function Documentation

void PLMD::PDB::addRemark ( const std::vector< std::string > & v1 )

Add information to the remark.

bool PLMD::PDB::checkForAtom ( const std::string & name ) const

Check if any of the atoms are named atom.

bool PLMD::PDB::checkForResidue ( const std::string & name ) const

Check if any of the residues are named name.

const std::vector< unsigned > & PLMD::PDB::getAtomBlockEnds ( ) const

Get the extents of the blocks containing the atoms.

std::string PLMD::PDB::getAtomName ( AtomNumber a ) const

return the name of a specific atom

const std::vector< AtomNumber > & PLMD::PDB::getAtomNumbers ( ) const

Access to the indexes.

void PLMD::PDB::getAtomRange	(	const std::string &	chainname,
		AtomNumber &	a_start,
		AtomNumber &	a_end,
		std::string &	errmsg
	)		const

Get the atoms in each of the chains.

const std::vector< double > & PLMD::PDB::getBeta ( ) const

Access to the beta array.

std::string PLMD::PDB::getChainID ( const unsigned & resnumber ) const

Get the chain ID that a particular residue is a part of.

void PLMD::PDB::getChainNames ( std::vector< std::string > & chains ) const

Get the names of all the chains in the pdb file.

AtomNumber PLMD::PDB::getNamedAtomFromResidue	(	const std::string &	aname,
		const unsigned &	resnum
	)		const

Return the atom named aname from residue number resnum.

AtomNumber PLMD::PDB::getNamedAtomFromResidueAndChain	(	const std::string &	aname,
		const unsigned &	resnum,
		const std::string &	chain
	)		const

Return the atom named aname from residue number resnum and chain.

Chain=="*" matches any chain and makes it equivalent to getNamedAtomFromResidue.

unsigned PLMD::PDB::getNumberOfAtomBlocks ( ) const

Get the number of blocks of atoms in the pdb.

const std::vector< double > & PLMD::PDB::getOccupancy ( ) const

Access to the occupancy array.

const std::vector< Vector > & PLMD::PDB::getPositions ( ) const

Access to the position array.

const std::vector< std::string > & PLMD::PDB::getRemark ( ) const

Access to the lines of REMARK.

std::string PLMD::PDB::getResidueName ( AtomNumber a ) const

return the residue name for a specific atom

std::string PLMD::PDB::getResidueName ( const unsigned & resnum ) const

get the name of the resnum'th residue

std::string PLMD::PDB::getResidueName	(	const unsigned &	resnum,
		const std::string &	chain
	)		const

get the name of the resnum'th residue of chain Chain=="*" matches any chain and makes it equivalent to getResidueName

unsigned PLMD::PDB::getResidueNumber ( AtomNumber a ) const

return the residue number for a specific atom

void PLMD::PDB::getResidueRange	(	const std::string &	chainname,
		unsigned &	res_start,
		unsigned &	res_end,
		std::string &	errmsg
	)		const

Get the residues in each of the chains.

bool PLMD::PDB::read	(	const std::string &	file,
		bool	naturalUnits,
		double	scale
	)

Read the pdb from a file, scaling positions by a factor scale.

bool PLMD::PDB::readFromFilepointer	(	FILE *	fp,
		bool	naturalUnits,
		double	scale
	)

Read from a file pointer.

void PLMD::PDB::setArgKeyword ( const std::string & new_args )

This is used to set the keyword ARG - this is so we we can use a1.

in the input for reference configurations

void PLMD::PDB::setPositions ( const std::vector< Vector > & v )

Set the position array.

unsigned PLMD::PDB::size ( ) const

Returns the number of atoms.
