# dump

Dump all kmers of an index as CSV, one row per kmer, with per-genome counts or presence.

```bash
obikmer dump INDEX [OPTIONS]
```

## Arguments

| Argument | Description |
|---|---|
| `INDEX` | Index directory to dump |

## Options

| Option | Default | Description |
|---|---|---|
| `--force-presence` | off | Output presence/absence (0/1) even if the index stores counts |
| `--debug` | off | Prefix each row with the partition and layer columns |
| `--head N` | none | Limit output to the first N kmers |

`dump` also accepts the shared [predicate options](filter.md#predicate-options) (`--ingroup`, `--outgroup`, `--min-count`, etc.) to restrict which kmers are dumped.

Output is CSV on stdout.
