 ## Feature filtering
 
-In the journal article three spectral cleaning steps are applied. In the first filter a Kruskal-Wallis test is used to identify features not reliably detected in the QC samples (p < 0.0001) of all batches. We follow the same parameters as the original article and do not use multiple test correction (`mtc = 'false'`).
