Try to obtain signals from CSADigitizer, but there is not PixelHit trees in the data.root File

Thanks for figuring out how to find the histogram. It works on the default example configuration. Thanks again.
However, when we want to implement the CSADigitizer on a 25-pixel detector configuration which was borrowed from
GeometryBuilderGeant4 module, passive volumes in GDML: Question/Issue.
It failed again to have the PixelHit tree. We tried both the positive and negative threshold in the setting of [CSADigitizer]. I appreciate your help in advance.
