YEs, you have to create a new layer that can be pass to the next algorithm in the modeler. It's not ideal, but there is no other way to o it, since selection is not something that can be stored in the layer, it is a QGIS thing, and as such cannot be used with layers not loaded such as the

Keep in mind that you need to have a license to write to sid files. If you only have the license to read sids, when you partition your existing 4GB sid, the output will most likely be geotiff which isn't as compressed as sid so the overall file size may be larger. On Apr 5, 2014 1:48 PM,
