i have similar issue as well
i had ran the Xtrige and yep it was suspected as twinning dataset
i can not define my space group so i ran bounch of space groups in the phaser
i got solution for p22121
every time i ran autobuild it failed ( my resolution is around 2.5)
i have not tried the nightly-build yet -- but i will
i open the map and model
some part of model can fit nicely but some part are messy
what sould i do ?
im thinking to do map modification .... will it work ? i know the tool on ccp4 but i have not got it right ... always failed.....
any suggestion ??

> I am having an issue with refining my structure. I have a 2.36 A resolution dataset. I have found a solution by molecular replacement in the space group P3221. I have been refining the structure, however, my Rfactor/Rfree are not decreasing even though I have good density. My current Rfactor/Rfree values are .40/.43. Can anyone help me?
there is a collection of things to think about at
