Getting "ERROR 000999: Failed to get raster"?

Question

I'm trying create a raster with

arcpy.MosaicToNewRaster_management

and this message appears in the end of the process:

Runtime error Traceback (most recent call last): File "", line 1, in File "c:\program files (x86)\arcgis\desktop10.2\arcpy\arcpy\management.py", line 12384, in MosaicToNewRaster raise e ExecuteError: ERROR 000999: Failed to get raster. Please check if the input parameters is correct. Failed to execute (MosaicToNewRaster).

My script is like this:

import arcpy
from arcpy import env

env.workspace = "C:\Users\user\Documents\ArcGIS\Default.gdb"
arcpy.MosaicToNewRaster_management("SG-21-Z-D.tif;SG-22-Y-C.tif;SH-21-X-B.tif;SH-22-V-A.tif", "marco", "marco.tif", "#", "#", "1", "BLEND", "#")

Should I change something?

Answer 1

You've got a file geodatabase as your workspace, which can't house tifs. Set your workspace to the folder containing the tifs or remove the .tif if the rasters are in your geodatabase.
