NAME

Bio::EnsEMBL::IdMapping::ScoredMappingMatrix - object holding a list of scored Entries

SYNOPSIS

# create a new ScoredMappingMatrix
my $gene_scores = Bio::EnsEMBL::IdMapping::ScoredMappingMatrix->new(
  -DUMP_PATH  => $dump_path,
  -CACHE_FILE => 'gene_scores.ser',
);

# add entries
my $gene_scores->add_Entry($entry1);

# serialise to file
$gene_scores->write_to_file;

# later, read these gene_scores from file
my $gene_scores1 = Bio::EnsEMBL::IdMapping::ScoredMappingMatrix->new(
  -DUMP_PATH  => $dump_path,
  -CACHE_FILE => 'gene_gene_scores.ser',
);
$gene_scores1->read_from_file;

DESCRIPTION

This object represents a collection of scores between source and target objects. It holds a list of Bio::EnsEMBL::IdMapping::Entry objects and has methods to retrieve indiviual or all Entries, as well as derived data like number of unique sources or targets, or various counts and averages.

It is the main collection for dealing with scored relationships in the stable Id mapping application.

new

Arg[1-N]    : see superclass
Example     : my $gene_scores = Bio::EnsEMBL::IdMapping::ScoredMappingMatrix->new(
                -DUMP_PATH   => $dump_path,
                -CACHE_FILE  => 'gene_scores.ser',
              );
Description : Constructor.
Return type : Bio::EnsEMBL::IdMapping::ScoredMappingMatrix
Exceptions  : none
Caller      : general
Status      : At Risk
            : under development

flush

Example     : $gene_scores->flush;
Description : Flushes (empties) the scoring matrix.
Return type : none
Exceptions  : none
Caller      : general
Status      : At Risk
            : under development

sub_matrix

Arg[1]      : Int $start - start index (inclusive)
Arg[2]      : Int $end - end index (inclusive)
Example     : # get the first 1000 elements in the matrix
              my $sub_matrix = $gene_scores->sub_matrix(1, 1000);
Description : Returns a sub-matrix of the ScoredMappingMatrix. The arguments
              ($start and $end) specify the position of the first and last
              element to return (inclusive, counting starts with element 1,
              not 0)
Return type : Bio::EnsEMBL::IdMapping::ScoredMappingMatrix
Exceptions  : none
Caller      : general
Status      : At Risk
            : under development

add_Entry

Arg[1]      : Bio::EnsEMBL::IdMapping::Entry $entry - Entry to add
Example     : $gene_scores->add_Entry($entry);
Description : Adds an Entry to the scoring matrix.
Return type : Float - the Entry's score
Exceptions  : thrown on wrong or missing argument
Caller      : general
Status      : At Risk
            : under development

update_Entry

Arg[1]      : Bio::EnsEMBL::IdMapping::Entry $entry - Entry to update
Example     : $gene_scores->update_Entry($entry);
Description : Updates an Entry (or rather its score) in the scoring matrix.
              Actually delegates to add_Entry(), only there as an intuitively
              named wrapper.
Return type : Float - the Entry's score
Exceptions  : thrown on wrong or missing argument
Caller      : general
Status      : At Risk
            : under development

add_score

Arg[1]      : Int $source - source object's internal Id ("dbID")
Arg[2]      : Int $target - target object's internal Id ("dbID")
Arg[3]      : Float $score - score for source/target pair
Example     : $gene_scores->add_score(1234, 5678, 0.997);
Description : Adds a score for a source/target pair to the scoring matrix.
              This is a low-level version of add_Entry().
Return type : Float - the score
Exceptions  : none
Caller      : general
Status      : At Risk
            : under development

set_score

Arg[1]      : Int $source - source object's internal Id ("dbID")
Arg[2]      : Int $target - target object's internal Id ("dbID")
Arg[3]      : Float $score - score for source/target pair
Example     : $gene_scores->set_score(1234, 5678, 0.997);
Description : Sets the score for a source/target pair in the scoring matrix.
              This method is similar to add_score, but assumes that the Entry
              has been added before, so won't update the sources and target
              lists.
Return type : Float - the score
Exceptions  : none
Caller      : general
Status      : At Risk
            : under development
