We found the origin of the problem but would like to see if you have edited some specific parameters in the web form related to the interaction matrix?
Did you change anything, or emptied may-be some fields?
Thank you for your response. I asked the research assistant who submitted the run and he said that he used the default settings and did not change anything. We are interested in finding out the interactions between the ligand dimer and DNA, not between the two ligands.
