thanks for the hint!
Actually I have been able to find and edit the python code in the qualitycheck.zip file, but the replacement of the max_value constant in the check_series_gaps function gave a wrong result with long series: it gives no gap though I know there are a few. Are there other global constants which I have to change in the check_metadata py module?
EDIT: also the "duplicate series" function miserably fails for long series. Therefore it must be something to edit, which lies outside the single functions. Please help me.
