I used Ancestry in the past but didn't really get much info, basically I'm Mediterranean which I know I am since that's where I grew up and links to some random 6th degree cousins which TBH could be anyone given that I'm from a country with a total population of ~4M.

I ended up downloading my data and canceling my Ancestry service since I wasn't comfortable with how that data could potentially be used in the future (one term of services change from sketchy stuff happening).

Question to people here, what can I do with this data I've downloaded? Data was surprisingly small, just 5MB - with 5 rows: rsid, chromosome, position, allele 1, allele 2. Is there any OSS software I can run on my machine to learn something useful about myself?
