# Submit a Spectrum

{% hint style="warning" %}
**Careful:**  At the moment, there is no way for users to *delete* or *update* spectral data (only to add new data).  So please double check your data (for example: graph it in excel or something) and make sure you have selected the right options in the form before submitting.

If an error occurs and you need help correcting it, don't hesitate to [contact us](https://www.fpbase.org/contact).
{% endhint %}

Spectral information can be submitted at [www.fpbase.org/spectra/submit/](https://www.fpbase.org/spectra/submit/).  Alternatively, if you would like to add fluorescent protein spectra on any given protein page, you can click "add spectrum" link or the <img src="https://3628226197-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LWgO4ROSn0Jb5Iyrwqq%2F-LXKONNNvh7-VszuZFfJ%2F-LXKOskNaIMdLYwKxKOt%2FScreen%20Shot%202019-01-28%20at%2011.59.36%20AM.png?alt=media&#x26;token=b38e3a33-00bf-4b6d-9382-73b71d86b198" alt="" data-size="line"> icon at the top left of the existing spectra.
