ArcGIS Raster Calculator won't work in main model

Question

I've created a sub-model in ArcGIS, which stretches my raster data to new values.

The strange thing is, that the model works, if I run it itself - as soon as I implement it in the main model, I get this error message:

ERROR 000539: Error running expression: rcexec() Traceback (most recent call last): File "", line 1, in File "", line 5, in rcexec File "c:\program files (x86)\arcgis\desktop10.2\arcpy\arcpy\sa\Functions.py", line 244, in Con where_clause) File "c:\program files (x86)\arcgis\desktop10.2\arcpy\arcpy\sa\Utils.py", line 47, in swapper result = wrapper(*args, **kwargs) File "c:\program files (x86)\arcgis\desktop10.2\arcpy\arcpy\sa\Functions.py", line 238, in Wrapper where_clause) File "c:\program files (x86)\arcgis\desktop10.2\arcpy\arcpy\geoprocessing_base.py", line 498, in return lambda *args: val(*gp_fixargs(args, True)) RuntimeError: ERROR 010240: Could not save raster dataset to C:\Users\Mattias\Documents\01_UNI\Diplomarbeit\GIS\DATA\data_out\scratch_IV.gdb\plus_ras with output format FGDBR. Failed to execute (Raster Calculator).

In my opinion, there's nothing wrong with my syntax - else it would not work in the sub-model directly...

Anyway, my map algebra expression is:

Con("%to_be_stretched%","%min_r_raster%",Con("%to_be_stretched%","%max_r_raster%",((("%to_be_stretched%" * 1.0) - "%min_in_raster%") / ("%max_in_raster%" - "%min_in_raster%")) * ("%max_r_raster%" - "%min_r_raster%") + "%min_r_raster%","VALUE >= %max_in%"),"VALUE <= %min_in%")

Answer 1

I"m guessing the issue is the temp workspace.

Check that the file geodatabase "C:\Users\Mattias\Documents\01_UNI\Diplomarbeit\GIS\DATA\data_out\scratch_IV.gdb\plus_ras" exists.

Answer 2

I get this same error when I try to write the raster calculator output to a network path that is too long and/or contains an odd character. When I write the output to my C: drive it works okay. The specific errors are the references to line 1, line, 8 and "could not save".

One solution is to write it to your C drive and then export it to the place that you want from ArcMap. (ArcGIS Desktop 10.7). Took me a while to figure this one out.
