Thanks for reporting the issue. We will look into it asap but due to the Covid crisis we are a bit slower than usual.

Hi @jiyanbio , thanks for reporting this issue.

If I understand your question correctly, you want to get Haddock score using this package. Unfortunately, the iScore package cannot directly provide you Haddock score. The Haddock scores in dataset 684 were not generated by this package but by Haddock software itself.

However, if you have Haddock models (Haddock pdb files), it's possible to calculate the Haddock score with iScore package. Let's take the 1ACB_1w.pdb file from dataset 684 as an example. Before reading the following example, it's better to have a look at what Haddock score is: https://www.bonvinlab.org/software/haddock2.2/scoring/.

Example: using iScore package to extract Haddock energies

>>> from iScore.energetic.haddock_energy import HaddockEnergy
>>> he = HaddockEnergy('1ACB_1w.pdb')
>>> he.read_energies()
# Eelec: electrostatic intermolecular energy
>>> he.ec
-256.513
# Evdw: van der Waals intermolecular energy
>>> he.evdw
-26.9989
Edesol: desolvation energy
>>> he.edesolv
16.2592

What the code above does is actually to extract the energy values from 1ACB_1w.pdb file. You could open the 1ACB_1w.pdb file and should find those values in the header.

After extracting the Haddock energies, then you can calculate the Haddock score with the equation given in the page https://www.bonvinlab.org/software/haddock2.2/scoring/. The Haddock models in dataset 684 are from Haddock water stage, so you need to use this euqation: HADDOCKscore-water = 1.0 Evdw + 0.2 Eelec + 1.0 Edesol + 0.1 Eair. The Eair is 0, so it can be ignored.
