Dear authors,

Your manuscript has been reviewed by two referees, and I am happy to see that both referees generally agree in their assessment that the work does not contain any major flaws. The referees however have a considerable number of comments, that will need to be addressed first before the manuscript can be considered for final publication. In general I agree with the proposed changes that you posted in the discussion, perhaps with the exception of the response to the issue of the order of experiments that both referees commented on. While your proposed text clearly describes the text, it does not contain your full reasoning, which is quite nicely explaining in the response to referee #1. So my suggestion is to include a full description of not only the choice you made, but also why you had to make them (large number of possibilities etc). This will make the reasoning much easier to follow for the average reader. I am looking forward to receiving a revised manuscript along the lines of your responses, along with a complete rebuttal document (which can be based on the responses).

Best regards

Ryan Teuling
