Thanks for the reply! It looks like I am/have been running 32 bit python (Python 2.7.6 (default, Nov 10 2013, 19:24:18) [MSC v.1500 32 bit (Intel)] on win32). I ran the script a few times trying to catch the error message that flashes for half a second before the command window closes and it says something like "FATAL ERROR (INDEF) \n directory full" I don't know what directory the message is referring to, but i'm not limited in disk space...any ideas?I also tried changing the following script, which, unmodified, runs perfectly fine in ArcMap:arcpy.sa.ZonalStatisticsAsTable(inFeatureRaster, zoneField_RQ, inValueRaster_RQ, workspace + inFeatureProjects + "_ZonalStatsTable_RQ", "NODATA", "MEAN")
to a non-existent zone field, and it threw an error as expected:ExecuteError: Failed to execute. Parameters are not valid.
ERROR 000864: Zone field: The input is not within the defined domain.
ERROR 000889: Invalid field type.
Failed to execute (ZonalStatisticsAsTable).
so it looks like python is calling on the right SA functions. Now i'm just seriously confused.
