[phenixbb] Phasing using CryoEM Map

Hello All, I trying to phase my 4Å data with low resolution cryoEM maps (various 12-18Å). There is some documentation, but not really for dealing with EM data. I am having trouble converting the EM data from mrc to suitable F's for phaser. One would want to try different density contours of the cryoEM map, but I haven't found a good way to accomplish this. I also have been unable to search for Ta6Br12 clusters using Autosol even though the documentation seems to suggest that it is possible using the "TX" or "XX" designation for heavy atom search. Any guidance would be extremely helpful. best, Alex
