Pdb models generated on Haddock 2.4 server

Just a short observation:
I submitted an NMR ensemble that was split during the Haddock run. I just noticed that the first pdb structure (protein1.pdb) has a larger file size and some weird additional protons in each amino acid. This does not happen when I split the models using the pdb toolbox.

Comparison of the last amino acids from protein1.pdb and protein1_2.pdb:

In which directory are you looking? Under data/ensemble?

The relevant files for the docking are the ones in the begin dir where missing atoms have been rebuilt.
I would not expect you will find those weird additional protons there.

They could be the result of the processing done on the first model with molprobity.
But they will be discarded since not following the naming convention of the force field used by HADDOCK.

Right, it was in the input directory (from the input tgz). The files in the begin directory are fine !
