[ensembl-dev] Fwd: Help with Bio::EnsEMBL::Mapper Class

[Andrés Arturo Lanzós Camaioni]

Hi.

My name is Andrés Lanzós and I am using the Ensembl API for the first time.

I want to map genes from primates in a genomic align.

First, I use the method get_Mapper () to transform the coordinates from
each original sequence to the alignment.

$this_mapper = $genomic_align->get_Mapper();


Then, I use the method list_pairs () to find the coordinates for each gene
in the alignment.

my $start0=$this_mapper->list_pairs($gene_id,$gene_start,$gene_end,$type);

But I have a problem with the fourth argument: $type, i do not know which
value to put.

Could yo help me with this?

My final objective is to extract the common regions between the genes for
the different species of the alignment.

Thank you.

Kind regards,
Andrés Lanzós.
