# Program seqretset

## Function

Reads and writes (returns) a set of sequences all at once

## Description

## Usage

Here is a sample session with seqretset.

    % seqretset
    Reads and writes (returns) a set of sequences all at once
    Input sequence set: embl:eclac*
    Output sequence [outfile.fasta]:

## Command line arguments

       Mandatory qualifiers:
      [-sequence]          seqset     Sequence set USA
      [-outseq]            seqoutset  Output sequence set USA

       Optional qualifiers: (none)
       Advanced qualifiers: (none)
       General qualifiers:
      -help                bool       report command line options. More
                                      information on associated and general
                                      qualifiers can be found with -help -verbose

Mandatory qualifiers | Allowed values | Default
--- | --- | ---
[-sequence] (Parameter 1) | Sequence set USA | Readable sequences | Required
[-outseq] (Parameter 2) | Output sequence set USA | Writeable sequences | <sequence>.format
Optional qualifiers | Allowed values | Default
(none)
Advanced qualifiers | Allowed values | Default
(none)

## Input file format

## Output file format

The output from seqretset is a set of sequences, and by default will be written in FASTA format all in one file.

In some cases the output filename will be the same as the input filename, but as seqretset reads all the sequences before opening the output file it will safely overwrite. Note that this is not true of seqretall which only reads the first sequence before opening the ouput file, but is true of seqret which reads the first sequence at startup.
