# Troubleshooting

### Singularity issues <a href="#extra-resources-and-getting-help" id="extra-resources-and-getting-help"></a>

Sometimes Singularity runs into problems when pulling multiple images at the same time for a pipeline run. In these instances it is sometimes better to pull the images manually into the directory that the pipeline will be run from, using for instance the following code:

```
singularity pull --name epidiverse-[PIPELINE]-[VERSION].simg \
docker://epidiverse/[PIPELINE]:[VERSION]
```

{% hint style="info" %}
Check the [Nextflow Documentation](https://www.nextflow.io/docs/latest/singularity.html) for more information about configuring Singularity
{% endhint %}

### Extra resources and getting help <a href="#extra-resources-and-getting-help" id="extra-resources-and-getting-help"></a>

If you still have an issue with running the pipeline then feel free to contact us at <info@epidiverse.eu> or by opening an issue in the respective pipeline repository on GitHub asking for help.

If you have problems that are directly related to Nextflow and not our pipelines then check out the [Nextflow gitter channel](https://gitter.im/nextflow-io/nextflow) or the [google group](https://groups.google.com/forum/#!forum/nextflow).
