Accessing and Downloading Your Raw Data

Important: The raw data provided by 23andMe is an advanced view of all the uninterpreted raw genotype data, including data that is not used in 23andMe reports. This data has undergone a general quality review however only a subset of markers have been individually validated for accuracy. As such, the data from 23andMe's Browse Raw Data feature is suitable only for research, educational, and informational use and not for medical or other use.

 

23andMe is preparing to transition customers located in Canada to an updated version of the 23andMe experience. You will receive an email when your account has been transitioned.

Accessing Your Raw Data

You can access your raw genetic data within your 23andMe account one of two ways:

  • Click on Tools in the navigation bar at the top of your homepage, and select Browse Raw Data from the available tools.

The main view of the Browse Raw Data feature shows the same pictorial representation of each chromosome — including a Y chromosome — for all users. It is important to note that except in rare genetic cases, women do not inherit a Y chromosome and will see “not determined” for markers found on the Y chromosome. 

Downloading Your Raw Data

To download your raw data, click on the Download tab from within the Browse Raw Data tool and enter your account password. If you have forgotten your account password but remember the answer to your security question, you can reset your password here. If you have forgotten both your password and the answer to your security question, please contact us for assistance.

Utility

The text file consists of lines of your genotype call data (your A's, T's, C's and G's). Keep in mind that having your data in hand may be of limited practical usefulness, depending on how much information you can extract from the data beyond what the 23andMe site already gives you.

Locating Your Downloaded File

The Raw Data file will be downloaded in the form of a zipped (.zip) text file, and begins with the word genome. If you are having trouble locating your raw data file, try searching your computer for a file containing the word “genome”. Once you have located your file in your Downloads folder or on your Desktop, you will need to double click or right click on the file to unzip it. An unzipped version of the file will then be located in your Downloads or Desktop folders.

Some computers may automatically unzip the file for you, in these cases, you will need to look for the text (.txt) file instead of the zipped (.zip) file.

Once you have located and unzipped your file, it can be opened in a text editor like WordPad or Excel.

The download feature requires you to re-enter your account password as well as the answer to the secret question that you chose during account setup.

Secret Question

When downloading your raw data, you will need to enter the answer to your secret question. If you have forgotten the answer to this question but are able to log in to your 23andMe account, you can change your secret question from the Account Settings page.

If you are not able to log in to your account, you will need to contact us in order to reset your secret question.

Locating your downloaded file 

The downloaded 23andMe Raw Data file naming scheme begins with the word genome, so you may want to search your computer for a file containing genome. Once you have located your file in your Downloads folder or on your Desktop, you will need to double click or right click on the file to unzip it. An unzipped version of the file will then be located in your Downloads or Desktop folders. 

Some computers may automatically unzip the file for you, in these cases, you will need to look for the text (.txt) file instead of the zipped (.zip) file.
