# Adding a Gene Set

Click the **+ Add gene set databases** button under the *Gene set databases* section header on the [library file management page](https://help.partek.illumina.com/partek-flow/user-manual/settings/components/library-file-management/library-file-management-page).

If you are using an assembly supported by Partek (e.g. human), a gene set from [geneontology.org](http://geneontology.org) will appear in the *Gene set database* drop-down list (Figure 1). Select the **Download gene set** **database** radio button and click **Create**.

![Figure 1. For many model organisms, automatic downloads of gene sets are available from the Partek repository (source: http://geneontology.org/)](https://1384254481-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FJVEESmJAPppJ3ijFq5aR%2Fuploads%2Fgit-blob-c94c9b694528a37582eb28e331275a974932c6c1%2Fadd-gene-set-db-human.png?alt=media)

If you prefer to add a custom gene set, or if you are working with a custom assembly, choose **Add gene set database** from the *Gene set database* drop-down list (Figure 2). Name the gene set by typing into the Custom Name box and click **Create**. Characters such as $ \* | \ : " < > ? / % cannot be used in custom names. A gene set file 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://help.partek.illumina.com/partek-flow/user-manual/settings/components/library-file-management/adding-a-reference-sequence)). When browsing for files on the Partek Flow server, only the files with relevant file extensions will be visible (.gmt and various compressed formats).
