# unitig
Dump the unitigs of an index as FASTA. A unitig is a maximal non-branching path through the de Bruijn graph implied by the index's kmers; the concatenation of every unitig reconstructs every stored kmer exactly once.
```bash
obikmer unitig INDEX [OPTIONS]
```
## Arguments
| Argument | Description |
|---|---|
| `INDEX` | Index directory |
## Options
`unitig` accepts the shared [predicate options](filter.md#predicate-options) (`--ingroup`, `--outgroup`, `--min-count`, etc.) to restrict which kmers are included before the unitigs are enumerated.
Output is FASTA on stdout.
