Now that your upload is done, you have the option to compute all your data at once. You just need to click on the rocket icon located in the top right section of the tool.
You will see these options to refresh all computations at once, based on your latest data. Now click "Confirm & Launch".
A series of jobs is then performed by the platform. When your number of jobs (in the top right section) goes back to a green status, this means all your data have been computed. You can navigate in the tool during the computation, which may take some time according to the number of items to be processed.
