Calculating compound dissimilarity matrix using NPClassifier...
NPClassifier calculations:
              There are compounds completely or partially not classified by
              NPClassifier due to missing SMILES and/or NPClassifier not
              producing full classifications for all compounds.
              If possible, consider adding classifications manually for these
              before running compDis() with type =  NPClassifier for optimal
              dissimilarity calculations. See ?compDis for details.
Done!
