Hi, thank you very much for proposing these solutions. However, I am not entirely sure that I'll manage to cope with that (I possibly misunderstand the use of inline variables). My worries are the following: I have read the "Iterate Rasters" tutorial and this is why I think I have a problem with my input data (my 50 GRID in the"output" folder). First, when I select this folder, I don't see the list of rasters appearing, such as in the tutorial where this list: "Aland_grid". "Aparcel_grid"... is displayed. I first thought I have a problem with my rasters but from what I saw on various forums, this is would be normal that I don't see them because at this stage, when I select the input raster, I am only supposed to select a folder. Is it the case or the fact that I don't see my list of rasters means that there is a problem With them? In my case, I select my input raster folder called "ouput" and the only output raster I have is "maat_e1000", which is the first in my list of rasters. If I understand the use of inline variable well, I can use the name of my ouput rasters as inline variables to create the name of the following output variables; by "following" I mean the output of the following tool I will use (in example 2 this is the "Project tool", for me it would be the "Minus" tool). However, I don't manage to create the 50 outputs I want by using Iterate raster because it seems to only consider 1 input raster ("maat_e1000, see the attached file) instead of the 50 rasters. So I still think that I first need to fix that: make sure that it will iterate on my 50 rasters. Well, I hope this clarifies a little bit my problem and will help to solve it, or at least I hope this would reveal where I am wrong! Thanks!
