# Class SequenceOutputOptions
Configuration for writing sequence (FASTA/FASTQ) files.

Defined in | <seqan/seq_io.h>
Signature | `struct SequenceOutputOptions`

## Member Variable Overview

- `int SequenceOutputOptions::lineLength`
  Length of the lines when writing out.
- `bool SequenceOutputOptions::qualMeta`
  Whether or not to write the meta information into the `"+"` line before the qualities (interpreted for FASTQ only). Default is `false`.

## Detailed Description

This struct is used for the configuration of writing out FASTA and FASTQ files.

## Member Variables Detail

### `int SequenceOutputOptions::lineLength`

Length of the lines when writing out.

Set to `-1` for default behaviour (no line break for FASTQ, line length of 70 for FASTA) and `0` for disabling line breaks.

### `bool SequenceOutputOptions::qualMeta`

Whether or not to write the meta information into the `"+"` line before the qualities (interpreted for FASTQ only). Default is `false`.
