**Using SnpEff in Galaxy: A few points to remember**

SnpEff relies on specially formatted databases to generate annotations. It will not work without them. There are several ways in which these databases can be obtained.

**Pre-cached databases**

Many standard (e.g., human, mouse, *Drosophila*) databases are likely pre-cached within a given Galaxy instance. You should be able to see them listed in **Genome** drop-down of **SnpEff eff** tool.

In you *do not see them* keep reading...

**Download pre-built databases**

SnpEff project generates large numbers of pre-build databases. To obtain and use them follow these steps:

  #. Use **SnpEff databases** tool to generate a list of existing databases. Note the name of the database you need.
  #. Use **SnpEff download** tool to download the database.
  #. Finally, use **SnpEff eff** by choosing the downloaded database from the history using *Downloaded snpEff database in your history* option of the **Genome source** parameter.

Alternatively, you can specify the name of the database directly in **SnpEff eff** using the *Download on demand* option (again, **Genome source** parameter). In this case snpEff will download the database before performing annotation.

**Create your own database**

In cases when you are dealing with bacterial or viral (or, frankly, any other) genomes it may be easier to create database yourself. For this you need:

 #. Download Genbank record corresponding to your genome of interest from NCBI or use annotations in GFF format accompanied by the corresponding genome in FASTA format.
 #. Use **SnpEff build** to create the database.
 #. Use the database in **SnpEff eff** (using *Custom* option for **Genome source** parameter).

Creating custom database has one major advantage. It guaranteess that you will not have any issues related to reference sequence naming -- the most common source of SnpEff errors.
