# Lists A list of features can be used to filter data or perform some analysis e.g. pathway enrichment analysis, or perform visualization like heatmap etc. * Click on gear button on Analysis page the top right corner * Choose **Settings** in the menu * Select **Lists** from the left panel of the *Components* section. To create new list, select the **+ New list** button on the top of the page and give the list a name. Choose between the three list options: * **Local file**: text file (.txt) on the local computer * **Text**: manually specify a list of names * **Hosted lists**: lists hosted by Illumina When manually specifying a local file or text, only the user who added the list can view and use the lists. The list name needs to be unique for each user. A description is optional. The list of features can be specified from a .txt file on your local computer by selecting the **Local file** option. The .txt file should contain only one feature per row.
To manually enter a list of genes, select the **Text** option. Content can be typed into the text field or pasted from the clipboard as one feature per row.
Select **Add list** to add the list. The new list will be added to the list table. When the *Hosted lists* option is chosen, lists can be downloaded by clicking the check box for each list on the left to select lists and click **Add list.**
View and sort the name of the list, number of features, owner, and creation date by clicking the column title of the list table. Click on the 3 dots under Actions column to download or edit the list:
