NAME
TFBS::Matrix - base class for matrix patterns, containing methods common to allDESCRIPTION
TFBS::Matrix is a base class consisting of universal constructor called by its subclasses (TFBS::Matrix::*), and matrix manipulation methods that are independent of the matrix type. It is not meant to be instantiated itself.FEEDBACK

The rest of the documentation details each of the object methods. Internal methods are preceded with an underscore.matrix
Title : matrix Usage : my $matrix = $pwm->matrix(); $pwm->matrix( [ [12, 3, 0, 0, 4, 0], [ 0, 0, 0,11, 7, 0], [ 0, 9,12, 0, 0, 0], [ 0, 0, 0, 1, 1,12] ]); Function: get/set for the matrix data Returns : a reference to 2D array of integers(PFM) or floats (ICM, PWM) Args : none for get; a four line string, reference to 2D array, or a 2D piddle for set
pdl_matrix
Title : pdl_matrix Usage : my $pdl = $pwm->pdl_matrix(); Function: access the PDL matrix used to store the actual matrix data directly Returns : a PDL object, aka a piddle Args : none
revcom
Title : revcom Usage : my $revcom_pfm = $pfm->revcom(); Function: create a matrix pattern object which is reverse complement of the current one Returns : a TFBS::Matrix::* object of the same type as the one the method acted upon Args : none
rawprint
Title : rawprint Usage : my $rawstring = $pfm->rawprint); Function: convert matrix data to a simple tab-separated format Returns : a four-line string of tab-separated integers or floats Args : none
prettyprint
Title : prettyprint Usage : my $prettystring = $pfm->prettyprint(); Function: convert matrix data to a human-readable string format Returns : a four-line string with nucleotides and aligned numbers Args : none
length
Title : length Usage : my $pattern_length = $pfm->length; Function: gets the pattern length in nucleotides (i.e. number of columns in the matrix) Returns : an integer Args : none
randomize_columns
Title : randomize_columns Usage : $pfm->randomize_columns(); Function: Randomizes the columns of a matrix Returns : Nothing Args : none
