# Adding a Gene Set Click the **+ Add gene set databases** button under the *Gene set databases* section header on the [library file management page](broken://spaces/5WPPw051cYE3Zthy5U7m/pages/9npv9u7RcPWHiXftGkmn). If you are using an assembly supported by Connected Multiomics (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 Connected Multiomics repository (Source: http://geneontology.org)

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 your local computer by clicking the option of *My Computer*. Only the files with relevant file extensions will be supported (.gmt and various compressed formats).
