Hey @Vojtech_Huser, I hear you that a ‘no’ would be helpful, but alas, ATLAS is too functional and does indeed support your desire:)
So, the current UI isn’t entirely intuitive, but here’s the link to see your cohort imported from the JSON file you shared: http://www.ohdsi.org/web/atlas/#/cohortdefinition/1769587
How do you get there?
Go to ‘Cohort Definitions’, click ‘New Cohort’, then go to the ‘Export’ tab and the ‘JSON’ button, paste the JSON from your file into the textbox, then click the ‘Reload’ button in the bottom-right below the textbox. Then go back to the ‘Definition’ tab, and you’ll see the cohort has been imported.
