Description

This method is used to get project the genes annotated in the reference chromosome into the Haplotype regions.

Methods

Methods description

    Function:   It fetches the slice or contig according to the input_id, 
                and it defines the database where the
                previous annotations are stored and create a Bio::EnsEMBL::Pipeline::GeneBuilder
                object for that genomic, input_id and db
    Returns :   nothing
    Args    :   none

    Usage   :   $self->new(-DBOBJ       => $db,
                           -INPUT_ID    => $id,
                           -SEQFETCHER  => $sf,
                           -ANALYSIS    => $analysis,
                          );

                           
    Function:   creates a Bio::EnsEMBL::Analysis::RunnableDB::HaplotypeProjection object
    Returns :   A Bio::EnsEMBL::Analysis::RunnableDB::HaplotypeProjection object
    Args    :   -dbobj:      A Bio::EnsEMBL::DBSQL::DBAdaptor (required), 
                -input_id:   Hap_pair input id (required), 
                -seqfetcher: A Sequence Fetcher Object,
                -analysis:   A Bio::EnsEMBL::Analysis (optional) 
                -extend:     determines the extension of the virtual contig
                             note: not implemented yet!
                -golden_path: determines the name of the golden path to use

    Title   :   write_output
    Usage   :   $self->write_output
    Function:   Writes output data to db
    Returns :   array of exons (with start and end)
    Args    :   none
