Bio::Tools::Run::Minimo(3) Wrapper for local execution of the Minimo assembler


use Bio::Tools::Run::Minimo;
# Run Minmo using an input FASTA file
my $factory = Bio::Tools::Run::Minimo->new( -minimum_overlap_length => 35 );
my $asm_obj = $factory->run($fasta_file, $qual_file);
# An assembly object is returned by default
for my $contig ($assembly->all_contigs) {

# Read some sequences

# Run Minimo using input sequence objects and returning an assembly file

  Wrapper module for the local execution of the DNA assembly program Minimo.
  Minimo is based on AMOS ( and
  implements the same conservative assembly algorithm as Minimus


Mailing Lists

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.

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


 Title   : new
 Usage   : $assembler->new( -min_len   => 50,
                            -min_ident => 95 );
 Function: Creates a Minimo factory
 Returns : A Bio::Tools::Run::Minimo object
 Args    : Minimo options available in this module:
     qual_in      Input quality score file
     good_qual    Quality score to set for bases within the clear
                    range if no quality file was given (default: 30)
     bad_qual     Quality score to set for bases outside clear range
                    if no quality file was given (default: 10). If your
                    sequences are trimmed, try the same value as GOOD_QUAL.
     min_len / minimum_overlap_length
                  Minimum contig overlap length (between 20 and 100 bp,
                    default: 35)
     min_ident / minimum_overlap_similarity
                  Minimum contig overlap identity percentage (between 0
                    and 100 %, default: 98)
     aln_wiggle   Alignment wiggle value when determining the consensus
                    sequence (default: 2 bp)
     out_prefix   Prefix to use for the output file path and name


 Title   : out_type
 Usage   : $factory->out_type('Bio::Assembly::ScaffoldI')
 Function: Get/set the desired type of output
 Returns : The type of results to return
 Args    : Desired type of results to return (optional):
                 'Bio::Assembly::IO' object
                 'Bio::Assembly::ScaffoldI' object (default)
                 The name of a file to save the results in


 Title   :   run
 Usage   :   $factory->run($fasta_file);
 Function:   Run TIGR Assembler
 Returns :   - a Bio::Assembly::ScaffoldI object, a Bio::Assembly::IO
               object, a filename, or undef if all sequences were too small to
               be usable
 Returns :   Assembly results (file, IO object or assembly object)
 Args    :   - sequence input (FASTA file or sequence object arrayref)
             - optional quality score input (QUAL file or quality score object


 Title   :   _run
 Usage   :   $factory->_run()
 Function:   Make a system call and run TIGR Assembler
 Returns :   An assembly file
 Args    :   - FASTA file
             - optional QUAL file


 Title   :   _clean_file
 Usage   :   $factory->_clean_file($file)
 Function:   Clean file in place by removing NULL characters. NULL characters
             can be present in the output files of AMOS 2.0.8 but they do not
             validate as proper sequence characters in Bioperl.
 Returns :   1 for success
 Args    :   Filename
