Bio::Tools::TargetP - Results of one TargetP run

   $targetp = Bio::Tools::TargetP->new(-file => 'targetp.out');

   # filehandle for TargetP :
   $targetp = Bio::Tools::TargetP->new( -fh  => \*INPUT );

TargetP modules will provides parsed information about protein localization. It reads in a targetp output file. It parses the results, and returns a Bio::SeqFeature::Generic object for each seqeunces found to have a subcellular localization


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.                  - General discussion  - About the mailing lists


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

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:

AUTHORS - Emmanuel Quevillon ^


Describe contact details here


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

analysis_method ^

 Usage     : $self->analysis_method();
 Purpose   : Inherited method. Overridden to ensure that the name matches
 Returns   : String
 Argument  : n/a

network ^

  Title   : network
  Usage   : $self->network($network)
  Function: This method Get/Set the network used for the analysis (PLANT or NON-PLANT)
  Example :
  Returns : string
  Arguments: On set, the network used

cleavage ^

  Title    :  cleavage
  Usage    : $self->cleavage($cleavage)
  Function : This method Get/Set if SignalP program was used to run TargetP
  Example  :
  Returns  : 1 or 0
  Arguments: On set, the cleavage used or not

next_prediction ^

  Usage    : $targetp->next_prediction()
  Purpose  : Returns the next TargetP prediction
  Returns  : A Bio::SeqFeature::Generic object
  Arguments: n/a

create_feature ^

  Title     : create_feature
  Usage     : $self->create_feature(\%hash);
  Function  : This method creates a new Bio::SeqFeature::Generic object
  Example   : 
  Returns   : Bio::SeqFeature::Generic
  Arguments : hash reference



 Title   : _initialize_state
 Usage   : n/a; usually called by _initialize() itself called by new()
 Function: This method is supposed to reset the state such that any 'history'
           is lost. State information that does not change during object
           lifetime is not considered as history, e.g. parent, name, etc shall
           not be reset. An inheriting object should only be concerned with
           state information it introduces itself, and for everything else
           call SUPER::_initialize_state(@args).

           The argument syntax is the same as for new() and _initialize(),
           i.e., named parameters following the -name=>$value convention.
           The following parameters are dealt with by the implementation
           provided here:
              -INPUT, -FH, -FILE
           (tags are case-insensitive).
 Example :
 Returns :
 Args    :


  Usage    : $targetp->_prediction()
  Purpose  : Returns the number of TargetP predictions
  Returns  : A scalar (number)
  Arguments: n/a


 Title     : _parsed
 Usage     : $targetp->_parsed(1)
 Function  : This method is used to know if the output result is parsed or not
             For internal use only
 Example   :
 Returns   : 1/0
 Arguments : 1/0 for setting


  Title    : _parse_results
  Usage    : $self->_parse_results()
  Function : This method parses a TargetP output
             For internal use only
  Example  :
  Returns  : n/a
  Arguments: none


 Title    : _parse_line
 Usage    : $self->_parse_line($line)
 Function : This method parses the line result
            For internal use only
 Example  :
 Returns  : Hash reference
 Arguemnts: line to parse


 Title    : _add_feature
 Usage    : $self->_add_feature($feature)
 Function : This method stores a feature object
            For internal use only
 Example  :
 Returns  : n/a
 Arguments: Bio::SeqFeature::Generic


 Title    : _toString_location
 Usage    : $self->_toString_location($key)
 Function : This method convert the 'one letter code' location to 
            the corresponding definition
            For internal use only
 Example  :
 Returns  : Location or undef
 Arguments: String
