Going back to Shane's issue with MR, I had a similar problem where I had a heavy atom dataset that seemed isomorphous with one of my native datasets. I tried making an isomorphous difference fourier map using Fs from my heavy atom data set and phases from my native MR solution. I couldn't make it work until I got a fresh MR solution into my heavy atom dataset and then the anomalous difference map made sense. Was there a better way that I could have used my native dataset instead of doing a second MR?
