## Function

Create random nucleotide sequences

## Description

makenucseq writes an output file with a set of random nucleotide sequences. The sequence composition is defined from reading a codon usage file: the sequences are created with triplet frequencies matching those given in the file, with the end trimmed to be in the correct reading frame. The number of sequences to create and length of each sequence is specified. Optionally, a user-defined string may be inserted into each output sequence at a specified position

## Algorithm

## Usage

Here is a sample session with makenucseq

    % makenucseq
    Create random nucleotide sequences
    Codon usage file (optional):
    Number of sequences created [100]:
    Length of each sequence [100]:
    nucleotide output sequence(s) [makeseq.fasta]:

Go to the output files for this example

Example 2

Providing a codon usage file specifies the sequence composition. This Pseudomonas aeruginosa file specifies a high GC content.

    % makenucseq
    Create random nucleotide sequences
    Codon usage file (optional): Epseae.cut
    Number of sequences created [100]:
    Length of each sequence [100]:
    nucleotide output sequence(s) [makeseq.fasta]:

Go to the output files for this example

## Input file format

makenucseq reads an optional codon usage file.

The input is a standard EMBOSS codon usage query.

Data can also be read from codon usage output in any supported format written by an EMBOSS or third party application.

The input format can be specified by using the command-line qualifier `-format xxx`, where 'xxx' is replaced by the name of the required format. The available format names are: emboss, cut, gcg, cutg, cutgaa, spsum, cherry, transterm, codehop, staden and numstaden.

## Output file format

makenucseq writes a sequence file with the number of sequences requested.
