Error in executing grid expression

tomwaddington — Tue, 08 Nov 2011 12:49:30 GMT

Can any one help, explain and possible provide a solution as to why this code keeps producing and error. Everything else runs up to this point and every variable is defined.

gp.MultiOutputMapAlgebra_sa("H:\Internship_Tom_Waddington\New_code/forest_b2grd = CON('H:\Internship_Tom_Waddington\New_code/forest_b1grd > 0,H:\Internship_Tom_Waddington\New_code/dem_resample')")

Traceback (most recent call last):
File "H:\Internship_Tom_Waddington\New_code\new_code.py", line 86, in <module>
gp.MultiOutputMapAlgebra_sa("H:\Internship_Tom_Waddington\New_code/forest_b2grd = CON('H:\Internship_Tom_Waddington\New_code/forest_b1grd > 0,H:\Internship_Tom_Waddington\New_code/dem_resample')")
ExecuteError: ERROR 010067: Error in executing grid expression.
Failed to execute (MultiOutputMapAlgebra).

in python you have to specify paths in one of these 3 ways:
r"c:\path"
"c:\\path"
"c:/path"

using "c:\path" won´t work.

Even with all the paths the same i.e. C:/path I still keep getting the Error in executing grid expression on the same line of code. Is there anything else that you think may be the cause?

Tom,

Don't have a grid file name long than 8 characters.
