The HBDA functions calculate H-bond forming properties of compounds such as the number of hydrogen bond donors or acceptors in a molecule.
Example
Let's calculate the donor count of the adenine nucleobase!
donorCount()
The CT calculation returns 2 as the donor count of adenine.
Let's examine thimine, its pair molecule in the structure of nucleic acids!
We calculate the acceptor count of thymine with CT:
acceptorCount()
