In particular, I am trying to reproduce the electrostatic interaction, which is calculated "between the unperturbed charge distributions of the prepared fragments as they are brought together at their final positions". Consequently, I have taken the multipole derived charges (MCD-q) and computed the electrostatic interaction as the sum of the classical coulombic interactions between the atoms of fragment1 and fragment2. The electrostatic energies I get are 10 times smaller that the ones given by the program. Even if I have approximate the atoms as puntual charges, I suspect that the agreement should be better. Does anyone know the way in which ADF calculates the electrostatic interaction? Could anyone give an advice? Thank you in advance for your attention. Regards.

It has plugins for sequence alignment and homology modeling as well. Bodil is available for Linux, Windows and IRIX at http://users.abo.fi/bodil/ Please take a look at the tutorial included in the download package (or at http://users.abo.fi/bodil/bodil_tutorial.zip, the link on the page seems to be broken) in order to get started. In particular, Tools/Superimpose/Vertaa superimposes protein structures based on alpha-carbon packing density. No sequence alignment is necessary. Tools/Superimpose/RMSD can then be used to compute the RMSD on the pairs of matching alpha-carbon atoms.
