The inclusion of the density-based correction in the db-MFCC scheme is able to reduce the errors substantially compared to the eb-MFCC scheme, resulting in errors per amino acid between 5 and 9 kJ/mol, again with the exception of 3SEM. While this is a substantial improvement -in particular when considering that no additional fragment calculations are required for evaluation the density-based correction on top of the eb-MFCC -the remaining errors show that the db-MFCC can only partially capture the two-body and higher-order interactions.
