Erratum: "Martini Coarse-Grained Model for Polyethylenimine" [J. Comput. Chem. 2019, 40, 607-618, DOI:10.1002/jcc.25747].

Correction of calculation errors in the original article led to the change of bead type for the unprotonated beads in the coarse-grained polyethylenimine model. The original model was still of good quality while the updated model showed better performance in describing the interaction between polyethylenimine and DNA.
