Bio::AnalysisResultI - Interface for analysis result objects
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.
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 constraints 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).
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with 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.
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
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
