Again, I appreciate all of your suggestions. I have tried many of them and I am excited to report that I have had great success with the Crank-2 Enhanced EP pipeline in ccp4 as recommended by Navraj Pannu. Even without my partial rosetta model, Crank2 was able to build a model that covers ~85% of my structure- much better than my partial rosetta model that only covers ~50%. Because I only gave crank2 my iodide dataset and my sequence, it was encouraging to see that the Crank2 model aligns quite well with my partial rosetta model. 

I hope that others who have datasets with weak anomalous signal give crank2 a try!

Thanks again,
Gabriel
