parseDataFile()

parseDataFile(array  $aFlines) : \Amelaye\BioPHP\Domain\Sequence\Entity\Sequence

Parses a TRANSFAC matrix data file and populates this manager's fields.

Parameters

array $aFlines

The lines the script has to parse

Throws

\Exception

Returns

__construct()

__construct() : mixed

Constructor.

Returns

mixed —

isEntryStart()

isEntryStart(string  $sLine) : bool

Tells whether a line opens a new TRANSFAC record, which the accession number does.

Parameters

string $sLine

The line to analyze

Returns

bool —

isEntryEnd()

isEntryEnd(string  $sLine) : bool

Tells whether a line closes a TRANSFAC record.

Parameters

string $sLine

The line to analyze

Returns

bool —

getEntryId()

getEntryId(array  $aFlines, string  $sLine) : string

Extracts the identifier uniquely naming a TRANSFAC record, its accession number.

Parameters

array $aFlines

The whole file, buffered
string $sLine

The line opening the entry

Returns

string —

getAccession()

getAccession() : string

Returns

string —

getId()

getId() : string

Returns

string —

getDateCreated() : string

Returns

string —

getDateUpdated()

getDateUpdated() : string

Returns

string —

readLabel()

readLabel(string  $sLine) : string

Reads the two-letter label a line carries.

Parameters

string $sLine

The line to analyze

Returns

string —

readData()

readData(string  $sLine) : string

Reads the data a line carries, which starts at its fifth column.

Parameters

string $sLine

The line to analyze

Returns

string —

parseCommonField()

parseCommonField(string  $sLabel, string  $sData) : bool

Reads the fields every TRANSFAC record carries, and says whether it did : a subclass calls this first and only looks at the labels of its own record when it did not.

Parameters

string $sLabel
string $sData

Returns

bool —

parseDate()

parseDate(string  $sData) : mixed

Parses one DT line, which dates either the creation or the last update of the record and may carry a time of day.

Format : DT 20.06.90 11:00:03 (created); ewi.

Parameters

string $sData

Returns

mixed —

append()

append(string  $sBuffer, string  $sData) : string

Appends the data of a line to a field written over several of them.

Parameters

string $sBuffer
string $sData

Returns

string —

splitList()

splitList(string  $sText, string  $sSeparator = ";") : array

Splits a field listing its values, semicolon separated and possibly closed by a period, into its items.

Parameters

string $sText
string $sSeparator

Returns

array —

parseMatrixRow()

parseMatrixRow(string  $sData) : array

Parses one row of the weight matrix, the label being the position it describes.

Format : 01 1 2 2 0 N

Parameters

string $sData

Returns

array —
