Dear all, I just solved my crystal structure and I was looking for my ligand. I have 4 molecules in the AU, but I found just in one molecule density for my ligand. In the other 3 molecules appeared deep red density when I tried to build something. Is this generally possible? The binding sites seem to be accessible for all 4 molecules.
Can anyone give some suggestion what happened or what I should do?
Thank you very much,
Marek
