... | create_bowtie_index [options] -d <my_dir> -i <my_index>

Options

[-?          | --help]                  #  Print full usage description.
[-x          | --no_stream]             #  Do not emit records.

[-O <file>   | --stream_out=<file>]     #  Write output to stream file         -  Default=STDOUT

Examples

To create a bowtie index from a FASTA file, do:

read_fasta -i <FASTA file(s)> | create_bowtie_index -d ~/my_dir -i my_index -x

You will then get the following files:

~/my_dir/my_index.1.ebwt
~/my_dir/my_index.2.ebwt
~/my_dir/my_index.3.ebwt
~/my_dir/my_index.4.ebwt
~/my_dir/my_index.rev.1.ebwt
~/my_dir/my_index.rev.2.ebwt

And finally to use this new index with bowtie_seq, simply do:

read_fasta -i <FASTA file(s)> | bowtie_seq -i ~/my_dir/my_index
