[GRASS-user] how to add a loop in the graphical modeler

[Victor Lundström]

Hi everyone,

I'm trying the start getting familiar with the graphical modeler as I have a lot of raster operations that I need to automate.
I have 456 raster layers that I (1) want to interpolate using v.surf.bspline, and then (2) export to six different folders, 76 rasters for each.

I have designed the workflow in the graphical modeler using just one layer to see that everything works the way that it should, and it does!
However, I can't for the life of me figure out how to set up a loop so that it can iterate through all the remaining layers. I'm trying my best to
read the manual, but since all of this is new to me, I can't figure out (1) how to add several raster layers. Whenever I use the "add data to model" I can
only add one layer from the drop down list. I also don't know if I need two loops, one for interpolation and then one for the raster export.

I have attached a screenshot that outlines my model. I hope you'll be able to guide me in the right direction!

Best,
Victor
