010331: Unable to construct a TEST expression.


Test failed in a map algebra expression because a valid logical expression could not be obtained. The reason could be the INFO selection expression and other parameters of the Test tool are not specified correctly.

The Test tool has two inputs. The first is the grid name, and the second parameter is a logical INFO selection expression. The logical expression must be contained within single or double quotes.


  • Make sure you are using the correct syntax.
  • Make sure that your logical expression makes a valid selection.
