EMBOSS: seqretall

| ## EMBOSS: seqretall

# Program seqretall

## Function

Reads and writes (returns) a set of sequences one at a time

## Description

This application is now replaced by "seqret" which is the same.

In early pre-release versions of EMBOSS, seqret read only one sequence so this program was needed to read more sequences. We have retained it for compatibility only.

## Usage

Here is a sample session with seqretall.

    % seqretall
    Reads and writes (returns) a set of sequences one at a time
    Input sequence(s): embl:eclac*
    Output sequence [eclac.fasta]:

## Command line arguments

       Mandatory qualifiers:
      [-sequence]          seqall     Sequence database USA
      [-outseq]            seqoutall  Output sequence(s) 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 database USA | Readable sequence(s) | Required
[-outseq] (Parameter 2) | Output sequence(s) USA | Writeable sequence(s) | <sequence>.format
Optional qualifiers | Allowed values | Default
(none)
Advanced qualifiers | Allowed values | Default
(none)

## Input file format

## Output file format

The output from seqretall 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, for example if you try to read the output from the example run with seqretall and give no output format.

As seqretall reads only the first sequence before opening the output file it will overwrite the sequences before reading has completed, with unpredictable result. Note that this is not true of seqretset which reads all sequences into memory at startup.
