When you have done your hybridization and scanned it, you can register information about the scanning process as a Scan item in BASE. A scan item holds information about the scanning process, such as which scanner and what settings you have used. It can also hold information about the images that was produced as well as the actual image files.

If you want you can upload the images from the scan to BASE. This is optional, but the images are needed if you want to create spot images later on.
To upload images for a scan you must first go to the single-item view for the scan. On this page you will find the Images tab which will take you to a list view of the images from this scan. New images are created in the same way as any other item in BASE, by clicking the New… button. You may add as many images as you like.
