Dear All,
I have a 3A structure, the quality of the data is not very good. Now I
have refined it to Rfree=40.7 in Refmac.
But it wonnot go further down. Then I used CNS to do annealing, then use
refmac to do rigid body refinement.
The Rfree converged to 0.34, but if I use restrain refinement it will go up
gradually. Then I use CNS refine
script to refine the anneal.pdb, then the rigid body of refmac refinement
converged at Rfree=0.33, but the refmac restrain
refinement will still increase the Rfree--given weighting=0.03, after 80
cycle Rfree is 0.38 and seems like still increasing.
Then I gave weighting=0.02, after 180 cycle, the Rfree is 0.37. I very
wonder if I give 1000 cycle to run, Rfree
will go back to 0.4. Can anybody give me some suggestions?
By the way, it is a dimer and I didnot use NCS restarin during
refinement. Below is from refmac log:
