Give standard usage here

Describe the object here # use of globals for configuration... # I've created the separate Config.pm module, and 'use'd it in the # main module, for instance... # other configuration globals: # $use_dash = [1|single|double|mixed]

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.

_register_program_commands()

 Title   : _register_program_commands
 Usage   : $assembler->_register_program_commands( \@commands, \%prefixes )
 Function: Register the commands a program accepts (for programs that act
           as frontends for a set of commands, each command having its own
           set of params/switches)
 Returns : true on success
 Args    : arrayref to a list of commands (scalar strings),
           hashref to a translation table of the form

 Note    : To implement a program with this kind of calling structure, 
           include a parameter called 'command' in the 
           @program_params global
 Note    : The translation table is used to associate parameters and 
           switches specified in _set_program_options with the correct
           program command. In the globals @program_params and
           @program_switches, specify elements as 'prefix1|param' and 
           'prefix1|switch', etc.

_set_program_options

 Title   : _set_program_options
 Usage   : $assembler->_set_program_options( \@ args );

_prepare_input_sequences

 Title   : _prepare_input_sequences
 Usage   : ($seqs, $quals) = $assembler->_prepare_input_sequences(\@seqs, \@quals);

           nothing happens. Overload this method in the specific assembly module
           if processing of the sequences is needed (e.g. as in the
           TigrAssembler module).
 Returns : - sequence input
           - optional quality score input
 Args    : - sequence input (FASTA file or sequence object arrayref)
           - optional quality score input (QUAL file or quality score object
               arrayref)
