Reads options (REQUIRED: either --fr, or (-f and -r)):¶

-f filename[.gz], --reads_fwd filename[.gz]

Name of forwards reads fasta or fastq file. Must be used with --reads_rev

-r filename[.gz], --reads_rev filename[.gz]

Name of reverse reads fasta or fastq file. Must be used with --reads_rev

--fr filename[.gz]

Name of interleaved fasta/q file

MUMmer options:¶

--cds_min_hit_length INT

Minimum hit length when running nucmer of CDS sequences against contigs [30]

--cds_min_hit_id FLOAT

Minimum hit percent identity when running nucmer of CDS sequences against contigs [80]

--ctg_min_hit_length INT

SMALT mapping options:¶

-k INT, --smalt_k INT

kmer hash length in SMALT (the -k option in smalt index) [15]

-s INT, --smalt_s INT

kmer hash step size in SMALT (the -s option in smalt index) [3]

-y FLOAT, --smalt_id FLOAT

Minimum identity threshold for mapping to be reported (the -y option in smalt map) [0.5]

External tools:¶

--gage_minid INT in [0,100]

Minimum percent identity used when GAGE runs nucmer [80]

--kraken_preload

Use the --preload option when running kraken

--ratt_config filename

Specify your own RATT config file [None]

Other options:¶

--ctg_layout_plot_title STRING

Title to use in contig layout plot [IVA QC contig layout and read depth]

--min_ref_cov INT

You must supply reads in one of two ways: 1) both --reads_fwd and --reads_rev; or 2) --fr. Also, you must either supply a reference with --embl_dir, or choose one automatically from a database with --ref_db.
