NAME
TFBS::PatternGen - a base class for pattern generators DESCRIPTION
TFBS::PatternGen is a base classs providing methods common to all pattern generating modules. It is meant to be inherited by a concrete pattern generator, which must have its own constructor. pattern Title : pattern Usage : my $pattern_obj = $patterngen->pattern() Function: retrieves a pattern object produced by the pattern generator Returns : a pattern object (currently available pattern generators return a TFBS::Matrix::PFM object) Args : none Warning : If a pattern generator produces more than one pattern, this method call returns only the first one and prints a warning on STDERR, In those cases you should use I<all_patterns> or I<patternSet> methods. patternSet Title : patternSet Usage : my $patternSet = $patterngen->patternSet() Function: retrieves a pattern set object containing all the patterns produced by the pattern generator Returns : a pattern set object (currently available pattern generators return a TFBS::MatrixSet object) Args : none all_patterns Title : all_patterns Usage : my @patterns = $patterngen->all_patterns() Function: retrieves an array of pattern objects produced by the pattern generator Returns : an array of pattern set objects (currently available pattern generators return an array of TFBS::Matrix::PFM objects) Args : none perl v5.14.2 2008-01-24 TFBS::PatternGen(3pm)
