Title : new Usage : my $pattrengen = TFBS::PatternGen::AnnSpec->new(%args); Function: the constructor for the TFBS::PatternGen::AnnSpec object Returns : a TFBS::PatternGen::AnnSpec object Args : This method takes named arguments; you must specify one of the following three -seq_list # a reference to an array of strings # and/or Bio::Seq objects # or -seq_stream # A Bio::SeqIO object # or -seq_file # the name of the fasta file containing # all the sequences Other arguments are: -binary # a fully qualified path to the 'meme' executable # OPTIONAL: default 'ann-spec' -additional_params # a string containing additional # command-line switches for the # ann-spec program
patternSetThe three methods listed above are used for the retrieval of patterns, and are common to all TFBS::PatternGen::* classes. Please see TFBS::PatternGen for details.
