Sparse To Dense

This node converts 'Sparse' binary (bitvector) or count (bytevector) fingerprints to the corresponding 'Dense' representation

NB Dense fingerprints are length-restricted to Integer.MAX_VALUE whereas Sparse fingerprints are restricted to Long.MAX_VALUE in length and Integer.MAX_VALUE cardinality

This node was developed by Vernalis Research. For feedback and more information, please contact
