# Adding a Variant Effect Predictor (VEP) Database

Click the **+ Add VEP database** button under the *VEP database* section on the [library file management page](https://help.connected.illumina.com/partek/partek-flow/user-manual/settings/components/library-file-management/library-file-management-page).

If you are using an species supported by Partek (i.e., human, mouse, rat), a VEP database from [ENSEMBL](http://www.ensembl.org/info/data/ftp/index.html) will be available for automatic download. Select the **Download database** radio button and click **Create** (Figure 1).

![Figure 1. For certain model organisms, automatic downloads of VEP databases are available](https://1384254481-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FJVEESmJAPppJ3ijFq5aR%2Fuploads%2Fgit-blob-6e9f023c34a5cd1183ae0c9b607af12756226ad0%2Fadd-vep-auto.png?alt=media)

If you are working with a custom assembly, choose the **Import database** radio button and click **Create** (Figure 2). A VEP database can be added from the *Partek Flow Server* or a *URL* download link. The behavior of each option is similar to when importing a reference sequence (see [Adding a Reference Sequence](https://github.com/illumina-swi/partek-docs/blob/main/docs/partek-flow/user-manual/settings/components/library-file-management/adding-reference-sequence.md)). ENSEMBL maintains an extensive list of VEP databases for various species. We recommend going to [ENSEMBL's ftp download site](http://www.ensembl.org/info/data/ftp/index.html) and finding the VEP database download link for your species of interest.

![Figure 2. VEP databases can be added for other species](https://1384254481-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FJVEESmJAPppJ3ijFq5aR%2Fuploads%2Fgit-blob-0b068b4db229fbb7941439f9a94e737f4a7f3e95%2Fadd-vep-custom.png?alt=media)

One VEP database is allowed per genome assembly. Once a VEP is successfully imported, the **+ Add VEP database** button will not be shown (Figure 3).
