# Microarray Library Files Microarray library files can be managed under *Microarray library files* section on *Other library files* tab on the *Library file management* page (Figure 1). The chip name and download source of stored Microarray library files will be shown in the table in this section.

Figure 1. Microarray libraries files section in Connected Multiomics library file management page.

Microarray probe tab files are used for processing microarray data in Connected Multiomics. When microarray intensity data files (e.g. Affymetrix .CEL files) are imported into a project, the chip type is automatically detected and the appropriate probe tab annotation file is downloaded. Thus, you would normally not need to manually add any probe tab annotation files. To add a custom probe tab file (e.g. for a custom chip), click the **+ Add probe sequence** button at the *Microarray library files* section (Figure 1). Scroll to the bottom of the *Chip name* drop-down list and choose **Other / Custom**. Name the chip by typing into the *Custom name* box and click the **Create** button (Figure 2). Characters such as $ \* | \ : " < > ? / % cannot be used in custom names.

Figure 2. Adding a custom probe tab file e.g. for a custom microarray chip.

A custom probe tab file can be added from your local computer by clicking the My Computer option. When browsing for files, only the files with relevant file extensions will be visible (.probe\_tab and various compressed formats). To add manifest, one needs to click the **+ Add manifest** button at the *Microarray library files* section (Figure 1). In the dialog, choose the right file from the dropdown list and push the Create button to compete the task (Figure 3).
