**What it does**

This tool uses `"snpEff build -genbank"` or `"snpEff build -gff3"` commands to create a snpEff database.

------

.. class:: infomark

**Working with Genbank files**

Using Genbank data for creating databases has several advantages:

 #. Genbank files contain annotations (such as locations of genes) together with sequences. This ensures that these two are in sync with each other.
 #. When you are analyzing small genomes (or not so small) it is much more convenient to create a database on the fly and use it.

 .. class:: warningmark

 SnpEff errors out on highly fragmented genomes containing multiple scaffolds. This is because a single gene may be split between multiple scaffolds causing SnpEff to crash. If this is happening use GFF route described below.

-------

**Genbank usage scenario**

Suppose you have a series of Illumina reads from an experiment involving *E. coli* K-12 MG1655. You want to map these reads to the reference genome of K-12 MG1655, call variants, and annotate them using snpEff. This tool enables you to follow the following analysis steps:

 #. Go to `NCBI <http://www.ncbi.nlm.nih.gov>`_ page for K-12 MG1655 genome (note that all NCBI genomes have similar list of files associated with them).
 #. Copy URL for file with extension `gbff.gz`
 #. Paste the URL into upload tool and set datatype to `genbank.gz`.
 #. Use this tool to generate a snpEff database and FASTA sequences from the dataset you've uploaded during the previous step.
 #. Use your Illumina reads to map against FASTA dataset generated in the previous step using BWA-MEM.
 #. Call variants using **Freebayes**.
 #. Annotate vcf output of Freebayes with **SnpEff eff** using database generated at step 2 (using *Custom* option for **Genome source** parameter).

In this scenario Genbank dataset is used twice. First, it is used to produce FASTA sequences that are using by BWA to map against. Second, it is used to create snpEff database. This guarantees that you will not have any issues related to reference sequence naming.

-------

.. class:: infomark

**Working with GFF files**

Alternatively you can create a SnpEff database from `GFF3 <https://en.wikipedia.org/wiki/General_feature_format>`_ files downloaded from NCBI or any other source. Using GFF dataset for building SnpEff database requires two inputs:

 #. The GFF file itself
 #. A genome in FASTA format

The GFF file contains coordinates of various features, but does not contain underlying sequences. This is why a FASTA file needs to be provided as well.

------

**GFF usage scenario**

The following example also uses *E. coli* K-12 MG1655:

#. Go to `NCBI <http://www.ncbi.nlm.nih.gov>`_ page for K-12 MG1655 genome.
#. Copy URLs for files with `gff.gz` and `fna.gz` extensions. The first file contains annotations in GFF3 format. The second file contains entire genome as a FASTA record.
#. Paste URLs into upload tool and set datatypes to `gff3` and `fasta.gz` for annotations and genome, respectively.
#. Use this tool to generate a snpEff database from the GFF dataset.
#. Map your reads against the FASTA dataset and continue as described in the above example.
