NAME

Bio::Tools::Run::AnalysisFactory - A directory of analysis tools

CONTENTS

SYNOPSIS



  # list all available analyses from the default location,
  # using a default (SOAP) access method
  use Bio::Tools::Run::AnalysisFactory;
  my $list = Bio::Tools::Run::AnalysisFactory->new();
                ->available_analyses;
  use Data::Dumper; print Dumper ($list);

  # ditto, but from a different location
  use Bio::Tools::Run::AnalysisFactory;
  my $list =
     Bio::Tools::Run::AnalysisFactory->new(-location => http://somewhere/something)
                ->available_analyses;

  # ...and using a different access method
  # (this example is not yet impelmented)
  use Bio::Tools::Run::AnalysisFactory;
  my $list =
     Bio::Tools::Run::AnalysisFactory->new(-location => http://somewhere/something,
                                           -access => novella)
                ->available_analyses;

  # list available categories of analyses
  use Bio::Tools::Run::AnalysisFactory;
  my $categories =
     Bio::Tools::Run::AnalysisFactory->new();
                ->available_categories;
  use Data::Dumper; print Dumper ($categories);

  # show all analyses group by categories
  use Bio::Tools::Run::AnalysisFactory;
  my $factory = Bio::Tools::Run::AnalysisFactory->new();
  foreach $cat ( @{ $factory->available_categories } ) {
    my @sublist = @{ $factory->available_analyses ($cat) };
    print "$cat:\n\t",
          join ("\n\t", @{ $factory->available_analyses ($cat) }),
          "\n";
  }

  # create an analysis object
  use Bio::Tools::Run::AnalysisFactory;
  $service = Bio::Tools::Run::AnalysisFactory->new();
                 ->create_analysis (edit.seqret);
  $service->run (
                #...
                )->results;



DESCRIPTION

The module represents a list of available analysis tools from a given location using a given access method. Additionally, for any of the available analyses, it can create an object of type Bio::Tools::Run::Analysis.

The module is a higher-level abstraction whose main job is to load a ’real-work-doing’ implementation. Which one is used, it depends on the -access parameter. The same design is used here as for Bio::Tools::Run::Analysis module.

There is available a SOAP access to almost all EMBOSS applications, running at European Bioinformatics Institute.

The documentation of all public methods are to be found in Bio::Factory::AnalysisI.

FEEDBACK

    Mailing Lists

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing list. Your participation is much appreciated.

    Support

Please direct usage questions or support issues to the mailing list:

bioperl-l@bioperl.org

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.

    Reporting Bugs

Report bugs to the Bioperl bug tracking system to help us keep track of the bugs and their resolution. Bug reports can be submitted via the web:

APPENDIX

Here is the rest of the object methods. Internal methods are preceded with an underscore _.

    new



 Usage   : my $factory =
             Bio::Tools::Run::AnalysisFactory->new(-access => soap,
                                                   -location => http://...);
 Returns : a new Bio::Tools::Run::AnalysisFactory object representing a list
           of available analyses
 Args    : There may be additional arguments which are specific
           to the access method (see methods new or _initialize
           of the access-specific implementations (such as module
           Bio::Tools::Run::AnalysisFactory::soap for a SOAP-based access).

           The recognised and used arguments are:
             -access
             -location
             -httpproxy
             -timeout



It builds, populates and returns a new Bio::Tools::Run::AnalysisFactory object. This is how it is seen from the outside. But in fact, it builds, populates and returns a more specific lower-level object, for example Bio::Tools::Run::AnalysisFactory::soap object - which one it is it depends on the -access parameter.
-access It indicates what lower-level module to load. Default is ’soap’. Other (but future) possibilities are:



   -access => novella
   -access => local



-location A location of the service. The contents is access-specific (see details in the lower-level implementation modules).

Default is http://www.ebi.ac.uk/soaplab/services (there are services running at European Bioinformatics Institute on top of most of EMBOSS analyses, and on some others).

-httpproxy In addition to the location parameter, you may need to specify also a location/URL of an HTTP proxy server (if your site requires one). The expected format is http://server:port. There is no default value. It is also an access-specific parameter which may not be used by all access methods.
-timeout For long(er) running jobs the HTTP connection may be time-outed. In order to avoid it (or, vice-versa, to call timeout sooner) you may specify timeout with the number of seconds the connection will be kept alive. Zero means to keep it alive forever. The default value is two minutes.

    _load_access_module



 Usage   : $class->_load_access_module ($access)
 Returns : 1 on success, undef on failure
 Args    : access should contain the last part of the
           name of a module who does the real implementation



It does (in the run-time) a similar thing as



   require Bio::Tools::Run::AnalysisFactory::$access



It prints an error on STDERR if it fails to find and load the module (for example, because of the compilation errors in the module).

    _guess_access



 Usage   : $class->_guess_access ($rh_params)
 Returns : string with a guessed access protocol (e.g. soap),
           or undef if the guessing failed
 Args    : rh_params is a hash reference containing parameters given
           to the new method.



It makes an expert guess what kind of access/transport protocol should be used to access the underlying analysis. The guess is based on the parameters in rh_params. Rememeber that this method is called only if there was no -access parameter which could tell directly what access method to use.

    VERSION and Revision



 Usage   : print $Bio::Tools::Run::AnalysisFactory::VERSION;
           print $Bio::Tools::Run::AnalysisFactory::Revision;
