Hello @alessiamarcolini @Christopher22 ,

From my understanding, when I apply the RandomTiler in Histolab, I get a tile with coordinate information for the bottom left and top right vertices in the file name PVALB054_seed16777216_tile_1_level0_1980-700-2280-900 ( I added in the other information that is not bolded). However, I'd like to know how these coordinates are calculated, because the image I'm using in this particular example measures 1767 pixels wide by 1519 pixels high. How is Histolab arriving at the numbers it is exporting? I'd appreciate any clarification you may have. Thanks :)
