Changing Rat Atlas from Duke to WHS

[Brianna Newton]

Hi, 

I am trying to change the default rat atlas from Duke to the WHS. When I go into DSI studio after downloading the WHS_rat_atlas_v4_pack.zip rat bundle, the entire rat folder is missing after I delete the Duke files. How do I enable the WHS rat  to be new atlas? 

Thank you for your help!
