Running TFlowFuzzy leads to an error message: 'Invalid counted values are available. Do you want to set this data to the active state?' In the log file there is written for several times: 'Invalid count value tolerance 0.000000 with count object zone...'.
The error message is caused by zero or empty values in the attribute tolerances. TFlowFuzzy requires tolerances > 0. Workaround: - Make sure that all counts have a tolerance > 0 - Use the option 'Use only network objects with volume > 0 and counted value > 0'.
