Synopsis
# VariationGroup feature representing the location of a haplotype block
$vgf = Bio::EnsEMBL::Variation::VariationGroupFeature->new
(-start => 100,
-end => 100,
-strand => 1,
-slice => $slice,
-variation_group => $vg);
...
# a variation group feature is like any other ensembl feature, can be
# transformed etc.
$vgf = $vgf->transform('supercontig');

print $vgf->variation_group()->name(), "\n";
Description
This is a class representing the genomic position of a VariationGroup. A
VariationGroup is a collection of tightly linked Variations sometimes
known as a Haplotype block.
Methods
Methods description
Arg [1] : none
Example : print $vgf->display_id(), "\n";
Description: Returns the 'display' identifier for this feature. For
VariationGroupFeatures this is simply the name of the variation
group it is associated with.
Returntype : string
Exceptions : none
Caller : webcode

Arg [-dbID] :
see superclass constructor
Arg [-ADAPTOR] :
see superclass constructor
Arg [-START] :
see superclass constructor
Arg [-END] :
see superclass constructor
Arg [-STRAND] :
see superclass constructor
Arg [-SLICE] :
see superclass constructor
Arg [-VARIATION_GROUP] :
Bio::EnsEMBL::Variation::VariationGroup - the variation group that this
feature represents the genomic position of.
Arg [-VARIATION_GROUP_NAME] :
string - the name of this variation group. This allows the name to be
rapidly obtained even when the VariationGroup has not been retrieved from
the database.
Arg [-VARIATION_GROUP_ID] :
int - the internal identifier of the variation group. This can be set
instead of the VariationGroup to allow the variation group to be
lazy-loaded later.
Example :
$vgf = Bio::EnsEMBL::Variation::VariationGroupFeature->new
(-start => 100,
-end => 100,
-strand => 1,
-slice => $slice,
-variation_group_name => $vg->name(),
-variation_group => $vg);
Description: Constructor. Instantiates a new VariationFeature object.
Returntype : Bio::EnsEMBL::Variation::Variation
Exceptions : none
Caller : general
Status : At Risk |
Arg [1] : Bio::EnsEMBL::Variation::VaritionGroup $vg (optional)
Example : print $vg->variation_group->name();
Description: Getter/Setter for the VariationGroup associated with this
feature. If not set and this feature has an associated adaptor,
an attempt will be made to lazy-load the variation from the
database.
Returntype : Bio::EnsEMBL::Variation::VariationGroup
Exceptions : throw on bad argument
Caller : general
Status : At Risk |
Arg [1] : string $newval (optional)
The new value to set the variation_group_name attribute to
Example : $variation_group_name = $obj->variation_group_name()
Description: Getter/Setter for the variation_group_name attribute
