I am using Modelbuilder to calculate several rasters with different parameters for each grid cell. One of the final steps is to calculate the log of one of the rasters using Raster calculator. Unfortunately, I get the error at that last final step:
ERROR 000539: Error running expression: rcexec() Traceback (most recent call last): File "", line 1, in File "", line 5, in rcexec TypeError: cannot concatenate 'str' and 'int' objects
Failed to execute (Raster Calculator).
My model looks that way:
I can imagine that one of the reasons is that the arrow to the "raster calculator" is not solid. But I dont know why. The rasters derived from the previous step are fine. When using raster calculator outside modelbuilder to do that last step, all works fine. I am a bit at a loss here.
