# mason\_genome(1)

Random Genome Simulation

## NAME

mason\_genome - Random Genome Simulation

## SYNOPSIS

**mason\_genome** \[*OPTIONS*\] \[**-l** *LEN*\]+ **-o** *OUT.fa*

## DESCRIPTION

Simulate a random genome to the output file.  For each **-l**/**--contig-length** entry, a contig with the given length will be simulated.

## OPTIONS

- **-h**, **--help**

  Display the help message.

- **--version**

  Display version information.

- **-q**, **--quiet**

  Set verbosity to a minimum.

- **-v**, **--verbose**

  Enable verbose output.

- **-vv**, **--very-verbose**

  Enable very verbose output.

### Simulation Configuration:

- **-l**, **--contig-length** List of *INTEGER*'s

  Length of the contig to simulate. Give one **-l** value for each contig to simulate. In range \[1..inf\].

- **-s**, **--seed** *INTEGER*

  The seed to use for the random number generator. Default: *0*.

### Output Options:

- **-o**, **--out-file** *OUTPUT\_FILE*

  Output file. Valid filetypes are: *.sam\[.\*\]*, *.raw\[.\*\]*, *.frn\[.\*\]*, *.fq\[.\*\]*, *.fna\[.\*\]*, *.ffn\[.\*\]*, *.fastq\[.\*\]*, *.fasta\[.\*\]*, *.faa\[.\*\]*, *.fa\[.\*\]*, and *.bam*, where \* is any of the following extensions: *gz*, *bz2*, and *bgzf* for transparent (de)compression.

## EXAMPLES

- **mason\_genome** **-l** 1000 **-l** 4000 **-o** *genome.fa*

  Simulate a genome with two contigs of lengths 1000 and 4000 and write it to genome.fa.
