Synopsis
use Bio::EnsEMBL::OligoFeature;
my $feature = Bio::EnsEMBL::OligoFeature->new(
-PROBE => $probe,
-MISMATCHCOUNT => 0,
-SLICE => $chr_1_slice,
-START => 1_000_000,
-END => 1_000_024,
-STRAND => -1,
);
Description
An OligoFeature object represents the genomic placement of an OligoProbe
object. The data are stored in the oligo_feature table.
Methods
Methods description
Arg [1] : int - number of mismatches
Example : my $mismatches = $feature->mismatchcount();
Description: Getter and setter for number of mismatches for this feature.
Returntype : int
Exceptions : None
Caller : General
Status : Medium Risk |
Arg [-PROBE] : Bio::EnsEMBL::OligoProbe - probe
An OligoFeature must have a probe. This probe must already be stored if
you plan to store the feature.
Arg [-MISMATCHCOUNT]: int
Number of mismatches over the length of the probe.
Arg [-SLICE] : Bio::EnsEMBL::Slice
The slice on which this feature is.
Arg [-START] : int
The start coordinate of this feature relative to the start of the slice
it is sitting on. Coordinates start at 1 and are inclusive.
Arg [-END] : int
The end coordinate of this feature relative to the start of the slice
it is sitting on. Coordinates start at 1 and are inclusive.
Arg [-STRAND] : int
The orientation of this feature. Valid values are 1, -1 and 0.
Arg [-dbID] : (optional) int
Internal database ID.
Arg [-ADAPTOR] : (optional) Bio::EnsEMBL::DBSQL::BaseAdaptor
Database adaptor.
Example : my $feature = Bio::EnsEMBL::OligoFeature->new(
-PROBE => $probe,
-MISMATCHCOUNT => 0,
-SLICE => $chr_1_slice,
-START => 1_000_000,
-END => 1_000_024,
-STRAND => -1,
);
Description: Constructor for OligoFeature objects.
Returntype : Bio::EnsEMBL::OligoFeature
Exceptions : None
Caller : General
Status : Medium Risk |
Args : Hashref with all internal attributes set
Example : none
Description: Quick and dirty version of new. Only works if the code is very
disciplined.
Returntype : Bio::EnsEMBL::OligoFeature
Exceptions : None
Caller : General
Status : Medium Risk |
Arg [1] : Bio::EnsEMBL::AffyProbe - probe
Example : my $probe = $feature->probe();
Description: Getter, setter and lazy loader of probe attribute for
OligoFeature objects. Features are retrieved from the database
without attached probes, so retrieving probe information for a
feature will involve another query.
Returntype : Bio::EnsEMBL::OligoProbe
Exceptions : None
Caller : General
Status : Medium Risk |
Args : None
Example : my $probelength = $feature->probelength();
Description: Getter for the length of the probe. Shortcut for
$feature->probe->probelength(), which should be used instead.
Originally, this method returned the length of the feature,
which was often, but not always, the same as the length of the
probe.
Returntype : int
Exceptions : None
Caller : General
Status : Medium Risk
: Use $feature->probe->probelength() because this may be removed |
Arg [1] : (optional) string - probeset
Example : my $probeset = $feature->probeset();
Description: Getter and setter for the probeset for this feature. Shortcut
for $feature->probe->probeset(), which should be used instead.
Probeset is not persisted if set with this method.
Returntype : string
Exceptions : None
Caller : General
Status : Medium Risk
: Use $feature->probe->probeset() because this may be removed |
