Hello Ulpu, We have changed the way that the expansion factors are calculated. From now on you will be able to mix the attributes so that for instance you might have several strata per province. The file that should be used is called **areas_per_attributes.csv** **areas_per_attribute.csv** and in this CSV you must have a column per attribute that will be used ( using the name of the attribute as the name of the header) followed by the area and the "weight" of the plot. Take for instance the Drylands Monitoring and Assessment project. In this project each plot has a **"From CSV"** type of attributes called dryland_region and dryland_category. For each dryland "region"( like Sahel or Central Asia) there are plots situated in different "dryland strata"(categories like Arid, Semiarid and so on). So the CSV with the areas and weights of the plots (per combination of attributes) are the combination of these values (**CHECK THE NAMES OF THE HEADERS!** ): dryland_region,dryland_category,area,weight Sahel,Hyperarid,163953200,3 Sahel,Arid,201048300,2 Sahel,Semiarid,154001400,1 Sahel,Dry subhumid,99204200,1 HornAfrica,Hyperarid,82949500,3 HornAfrica,Arid,144818400,2 HornAfrica,Semiarid,143918800,1 HornAfrica,Dry subhumid,48291800,1 NorthernAfrica,Hyperarid,416110100,3 NorthernAfrica,Arid,96377700,2 NorthernAfrica,Semiarid,37256500,1 NorthernAfrica,Dry subhumid,15009000,1 ... So if in your project you have an attribute called *country* then you should include an **areas_per_attributes.csv** **areas_per_attribute.csv** file inside the CEP file that would look like this (in this example the country will only be Zanzibar): country,area,weight Zanzibar,150733,1 Then put this file that you generated inside the CEP file that was generated using Collect designer (you can open it as a ZIP file) Hope this helped!
