Options

[-?          | --help]                  #  Print full usage description.
[-x          | --no_stream]             #  Do not emit records.
[-i <string> | --index_name=<string>]   #  Directory name to contain index files.
[-p <uint>   | --prefix_length=<uint>]  #  Minimum prefix that can be matched  -  Default=guessed
[-I <file!>  | --stream_in=<file!>]     #  Read input from stream file         -  Default=STDIN
[-O <file>   | --stream_out=<file>]     #  Write output to stream file         -  Default=STDOUT
[-v          | --verbose]               #  Verbose output.

Examples

To create the Vmatch index from a FASTA file, do:

read_fasta -i <FASTA file(s)> | create_vmatch_index -i ~/my_vmatch_dir/my_vmatch_index -x

You will then get the following files:

~/my_vmatch_dir/my_vmatch_index.al1
~/my_vmatch_dir/my_vmatch_index.bck
~/my_vmatch_dir/my_vmatch_index.des
~/my_vmatch_dir/my_vmatch_index.lcp
~/my_vmatch_dir/my_vmatch_index.llv
~/my_vmatch_dir/my_vmatch_index.prj
~/my_vmatch_dir/my_vmatch_index.sds
~/my_vmatch_dir/my_vmatch_index.suf
~/my_vmatch_dir/my_vmatch_index.tis

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

read_fasta -i <FASTA file(s)> | vmatch_seq -i ~/my_vmatch_dir/my_vmatch_index
