i have a multi domain protein data of 3.28 A resolution
the completness is 92 %
it is a 68 KDa protein 3 domains individually i used in phaser and i got the solution but with 4th domain when i am running phaser solution i am getting but the density is not so clear for that .
is this due to 92 % completness of data. without 4th domain the R factor and  R fre e is 29 / 40
