       Bio::Assembly::IO::bowtie - An IO module for assemblies in Bowtie format *BETA*


        $aio = Bio::Assembly::IO( -file   => "mybowtie.bowtie",
                                  -index  => "myindex",
                                  -format => "bowtie");
        $assy = $aio->next_assembly;


       This is a read-only IO module designed to convert Bowtie
       (<>) formatted alignments to Bio::Assembly::Scaffold
       representations, containing Bio::Assembly::Contig and Bio::Assembly::Singlet objects.  It
       is a wrapper that converts the Bowtie format to BAM format taken by the
       Bio::Assembly::IO::sam module which in turn uses lstein's Bio::DB::Sam to parse binary
       formatted SAM (.bam) files guided by a reference sequence fasta database.

       Some information is lost in conversion from bowtie format to SAM/BAM format that is
       provided by Bowtie using the SAM output option and the conversion to SAM format from
       bowtie format is slower than using bowtie's SAM option.  If you plan to use SAM/BAM format
       it is preferable to use this Bowtie option rather than convert the format after the fact.

       See the Bio::Assembly::IO::sam documentation for relevant details.


       ·   Required files

           A bowtie (".bowtie") alignment and the bowtie index or fasta file used to generate the
           alignment are required.

       ·   Compressed files

           ...can be specified directly , if IO::Uncompress::Gunzip is installed. Get it from
           your local CPAN mirror.


   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.

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

        Usage   : my $obj = new Bio::Assembly::IO::bowtie();
        Function: Builds a new Bio::Assembly::IO object
        Returns : an instance of Bio::Assembly::IO
        Args    : hash of options:

                   -file    => bowtie_output_file
                   -index   => bowtie_index or fasta_file used to create index
                   -no_head => boolean skip SAM header
                   -no_sq   => boolean skip SQ lines of SAM header
