Dear ALL: We are trying to do a molecular replacement using EPMR. IT is weird that we got high CC(0.58) but with high R factor about 0.89 as well. The second tier of solutions have cc about 0.54 and R factor about 0.95. How can we optimize our EPMR trials to get a definitive correct solutions? Thanks a lot for the help. Have a nice weekend!
