Hello,I try the code below I get the following error:Executing: SingleOutputMapAlgebra ((I:\giswork\mattandpeter\MD_ansense_001 + I:\
giswork\mattandpeter\MD_ansense_002 + I:\giswork\mattandpeter\MD_ansense_003) \
3) I:\giswork\mattandpeter\MDE_001test #
Start Time: Wed Jun 02 10:59:15 2010
Failed to execute. Parameters are not valid.
ERROR 010394: Map Algebra expression: Syntax error at location 1 (around (I:\g)
of expression ((I:\giswork\mattandpeter\MD_ansense_001 + I:\giswork\mattandpeter

Failed to execute (SingleOutputMapAlgebra).
End Time: Wed Jun 02 10:59:15 2010 (Elapsed Time: 0.00 seconds)
However, this command works fine in Raster Calculator. I don' t know what's wrong with my syntax for SOMA. I've tried forward and back slashes. Any ideas on how I can get this to work? Or why its not working?Thanks,Mike
