**What it does**

This tool downloads the master list of snpEff databases from a remote SnpEff repository. You can then look at this list and decide which database to use for your analysis. For example, if **List entries matching the following expression** parameter of this tool is set to *Mouse*, it will produce a tabular dataset with the following content::

    mm10  Mouse
    mm39  Mouse
    mm9   Mouse

This means that there are three available snpEff databases for mouse genome. If you want to use mm39 in you analysis:

 - set **Genome source** option of **SnpEff eff** Galaxy tool to *Download on demand*
 - enter 'mm39' into **Snpff Genome Version Name** text box

-------

.. class:: infomark

**The usage scenario**

There are two ways to use names of databases obtained with this tool in Galaxy's version on snpEff:

    #. Use **SnpEff download** tool. It will download the database to the history and you will be able to use it in **SnpEff eff** tool using *Downloaded snpEff database in your history* option of the **Genome source** parameter.
    #. Use *Download on demand* option of the **SnpEff eff** tool (again, **Genome source** parameter). In this case snpEff will download the database before performing annotation.
