Bio::AnalysisResultI - Interface for analysis result objects
Package variables
No package variables defined.
Included modules
Inherit
Synopsis
Bio::AnalysisResultI defines an interface that must be implemented by
a subclass. So you cannot create Bio::AnalysisResultI objects,
only objects that inherit from Bio::AnalysisResultI.
Description
The AnalysisResultI module provides an interface for modules
encapsulating the result of an analysis that was carried out with a
query sequence and an optional subject dataset.
The notion of an analysis represented by this base class is that of a unary or
binary operator, taking either one query or a query and a subject and producing
a result. The query is e.g. a sequence, and a subject is either a sequence,
too, or a database of sequences.
This interface defines methods to access analysis result data and does
not impose any contraints on how the analysis result data is acquired.
Note that this module does not provide support for running an analysis.
Rather, it is positioned in the subsequent parsing step (concerned with
turning raw results into BioPerl objects).
Methods
Methods description
Usage : $date = $result->analysis_date();
Purpose : Get the date on which the analysis was performed.
Returns : String
Argument : n/a |
Usage : $meth = $result->analysis_method();
Purpose : Get the name of the sequence analysis method that was used
to produce this result (BLASTP, FASTA, etc.). May also be the
actual name of a program.
Returns : String
Argument : n/a |
Usage : $vers = $result->analysis_method_version();
Purpose : Get the version string of the analysis program.
: (e.g., 1.4.9MP, 2.0a19MP-WashU).
Returns : String
Argument : n/a |
Usage : $query_obj = $result->analysis_query();
Purpose : Get a Bio::PrimarySeqI-compatible object representing the entity
on which the analysis was performed. Lacks sequence information.
Argument : n/a
Returns : A Bio::PrimarySeqI-compatible object without sequence information.
The sequence will have display_id, description, moltype, and length data. |
Usage : $obj = $result->analyis_subject();
Purpose : Get the subject of the analysis against which it was
performed. For similarity searches it will probably be a database,
and for sequence feature predictions (exons, promoters, etc) it
may be a collection of models or homologous sequences that were
used, or undefined.
Returns : An object of a type the depends on the implementation
May also return undef for analyses that don\'t involve subjects.
Argument : n/a
Comments : Implementation of this method is optional.
AnalysisResultI provides a default behavior of returning undef. |
Usage : $vers = $result->analyis_subject_version();
Purpose : Get the version string of the subject of the analysis.
Returns : String or undef for analyses that don\'t involve subjects.
Argument : n/a
Comments : Implementation of this method is optional.
AnalysisResultI provides a default behavior of returning undef. |
Title : next_feature
Usage : $seqfeature = $obj->next_feature();
Function: Returns the next feature available in the analysis result, or
undef if there are no more features.
Example :
Returns : A Bio::SeqFeatureI implementing object, or undef if there are no
more features.
Args : none |
