NAME

       TFBS::Word - IUPAC DNA consensus word-based pattern class =head1 DESCRIPTION

       TFBS::Word is a base class consisting of universal constructor called by its subclasses (TFBS::Matrix::*), and word pattern manipulation
       methods that are independent of the word type. It is not meant to be instantiated itself.

   new
	Title	: new
	Usage	: my $pwm = TFBS::Matrix::PWM->new(%args)
	Function: constructor for the TFBS::Matrix::PWM object
	Returns : a new TFBS::Matrix::PWM object
	Args	: # you must specify the -word argument:
		  -word,       # a strig consisting of letters in
			       # IUPAC degenerate DNA alphabet
			       # (any of ACGTSWKMPYBDHVN)

		  #######

		  -name,	# string, OPTIONAL
		  -ID,		# string, OPTIONAL
		  -class,	# string, OPTIONAL
		  -tags 	# a hash reference reference, OPTIONAL

   search_seq
	Title	: search_seq
	Usage	: my $siteset = $pwm->search_seq(%args)
	Function: scans a nucleotide sequence with the pattern represented
		  by the PWM
	Returns : a TFBS::SiteSet object
	Args	: # you must specify either one of the following three:

		  -file,       # the name od a fasta file (single sequence)
		     #or
		  -seqobj      # a Bio::Seq object
			       # (more accurately, a Bio::PrimarySeqobject or a
			       #  subclass thereof)
		     #or
		  -seqstring # a string containing the sequence

		  -max_mismatches,  # number of allowed positions in the site that do
				    # not match the consensus
					    # OPTIONAL: default 0

   search_aln
	Title	: search_aln
	Usage	: my $site_pair_set = $pwm->search_aln(%args)
	Function: Scans a pairwise alignment of nucleotide sequences
		  with the pattern represented by the word: it reports only
		  those hits that are present in equivalent positions of both
		  sequences and exceed a specified threshold score in both, AND
		  are found in regions of the alignment above the specified
		  conservation cutoff value.
	Returns : a TFBS::SitePairSet object
	Args	: # you must specify either one of the following three:

		  -file,       # the name of the alignment file in Clustal
				      format
		     #or
		  -alignobj	 # a Bio::SimpleAlign object
			       # (more accurately, a Bio::PrimarySeqobject or a
			       #  subclass thereof)
		     #or
		  -alignstring # a multi-line string containing the alignment
			       # in clustal format
		  #############

		  -max_mismatches,  # number of allowed positions in the site that do
				     # not match the consensus
					     # OPTIONAL: default 0

		  -window,     # size of the sliding window (inn nucleotides)
			       # for calculating local conservation in the
			       # alignment
			       # OPTIONAL: default 50

		  -cutoff      # conservation cutoff (%) for including the
			       # region in the results of the pattern search
			       # OPTIONAL: default "70%"

NAME

       TFBS::PatternI - interface definition for all pattern objects (currently includes matrices and word (consensus and regular expressions )

DESCRIPTION

       TFBS::PatternI is a draft class that should contain general interface for matrix and other (future) pattern objects. It is not defined and
       not used yet, as I need to ponder over certain unresolved issues in general pattern definition. User feedback is more than welcome.
