Hi, I have a problem with the following sentence: "if I collect all spots I get good map, but it is impossible to solve the structure by molecular replacement" - if you have a good map (I assume electron density map) then the structure is solved... for me a good map is a map I can interpret.

Dear all, I have a particular problem... so, I have a beautiful crystal with nice diffraction pattern at 2.7A. The diffraction images are composed by very strong spots and weak spots. With XDS, if I collect all spots I get good map, but it is impossible to solve the structure by molecular replace
