## Function

Create random protein sequences

## Description

makeprotseq writes an output file with a set of random protein sequences. The sequence composition is defined from reading a pepstats output file of protein composition: the sequences are created with amino acid frequencies matching those given in the file. 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 makeprotseq

    % makeprotseq
    Create random protein sequences
    Pepstats program output file (optional):
    Number of sequences created [100]:
    Length of each sequence [100]:
    protein output sequence(s) [makeseq.fasta]:

Go to the output files for this example

Example 2

    % makeprotseq
    Create random protein sequences
    Pepstats program output file (optional): ../pepstats-keep/laci_ecoli.pepstats
    Number of sequences created [100]:
    Length of each sequence [100]:
    protein output sequence(s) [makeseq.fasta]:

## Output file format

The output is a standard EMBOSS sequence file.

The results can be output in one of several styles by using the command-line qualifier `-osformat xxx`, where 'xxx' is replaced by the name of the required format. The available format names are: embl, genbank, gff, pir, swiss, dasgff, debug, listfile, dbmotif, diffseq, excel, feattable, motif, nametable, regions, seqtable, simple, srs, table, tagseq.

See: http://emboss.sf.net/docs/themes/SequenceFormats.html for further information on sequence formats.
