When a reading is "N", convert the reading to "0" or "5" or some other value.

The Feature

Could we add a feature where, when a certain reading is "N", it is converted to "0" or "5" or some other value? This way, values that rarely change won't be affected by errors, and values with decimal points that have errors can simply be changed to "0".

[SybexX]

This is already implemented. If you are activated PreValueUse and there is a valid Value/PreValue, the "N" are replaced with the number from the PreValue.

[Zuray-wzj]

Isn't PreValueUse only set to the default value "true"? Is it changed in the original file?

[SybexX]

The default value is "true", but you can also deactivate it on the configuration page.

The "N" are replaced at this point: ClassFlowPostProcessing.cpp

[Zuray-wzj]

After disabling it, it shows "PreValue deactivated". Where do I input the numbers? Should I directly modify the ClassFlowPostProcessing.cpp file? Does it mean that after an error occurs, all values will be changed to the replacement values? Can each row have different values? For example, the first replacement is "1", the second one is "0", and the third value is "5", like that.

[SybexX]

If you activate Prevalueuse and there is a valid Prevalue, the "N" will automatically be replaced by the correct numbers.
If a number is only recognized with "N", you should rather try something with the camera settings until this number is correctly recognized.
