How do I set a default genetic file?

In your account, under "My DNA files" you might want to upload files from multiple sources. For example, the user below has 2 sets of data, one from 23andMe and another from Ancestry.com, and chooses to upload both.

When you move your cursor on top of a set, you will see you know have a number of options: to edit the name of your file, to delete your data, or to set this particular dataset as DEFAULT. Simply tick the box where it says "Set as default dataset". you can change this at any time, before any purchase.
