Many passing tests contain general condenser, in source:systemtest/testcases_petascope/test_wcps/queries so I'd assume it's some error in your query. Have a look at:

• source:systemtest/testcases_petascope/test_wcps/queries/24-condense_coverage_one_var.test
• source:systemtest/testcases_petascope/test_wcps/queries/25-condense_field_two_vars.test
• source:systemtest/testcases_petascope/test_wcps/queries/27-construct_boring_histogram.test
• source:systemtest/testcases_petascope/test_wcps/queries/28-construct_histogram_range_condition.test
• source:systemtest/testcases_petascope/test_wcps/queries/29-filter_image(lines).test
• source:systemtest/testcases_petascope/test_wcps/queries/31-Discrete_Fourier.test
• source:systemtest/testcases_petascope/test_wcps/queries/32-construct_condense_cosinus_gray_image.test
• source:systemtest/testcases_petascope/test_wcps/queries/33-construct_condense_gray_image.test
• source:systemtest/testcases_petascope/test_wcps/queries/41-filter_calculation_reloaded.test
• source:systemtest/testcases_petascope/test_wcps/queries/42-filter_calculation.xml

[Dimitar Misev]

Reopened, the problem is that variables in petascope are required to start with a '$', whereas in the WCPS standard they are not.

[Peter Baumann]

This generality (ie, leaving out the $ prefix for variable identification) will have to be abandoned when uniting WCPS with XQuery, so in future the $ will be mandatory anyway.

[abeccati]

There is more relevant ticket to be used as reference for $ involving issues (see #303).
