If you see enough in your map, just build a backbone model and use that to generate a crude mask for DM (in case you can apply NCS averaging).

I can find the Se site and get the phase, but the density map is not so good. Some part of the protein (about 1/3) has a homologue model which is also can be found using Phaser. The homologue region has a good map while other region only show a poor map. I think the combination of experimental phase and MR phase might improve the map. Is there anybody can help find which program can work on this?
