I am running the nutrient retention model and have two questions:
1) A good bit of time is being taken up by a process that looks like "ReprojectImage" in the message log. I tried feeding in a layer with a different projection on purpose just to see what would happen, and I got a warning right away. I am not getting this same warning message when I input my real (same projection) inputs, so I am pretty sure they really do have the same projection.
Do you know if this ReprojectImage process indicates that there is some problem?
2) I also get a warning message that looks like: "no flow direction found for 0 1" etc. up to 0 15. What do these numbers represent? I am wondering if they are cells on the edge of my DEM, or if there may be something wrong with my DEM.
