Hi Heather,

Hmm... a little hard to tell what the problem is.

So first:  autobuild should have refined this model as one of the first things it did.  Did it get about the same R that you got when refining it directly with phenix.refine?  If no, then have a look at the refinement .eff files (the autobuild one is in AutoBuild_run_1_/TEMP0 unless that was cleaned up) and see what is different.

Next....what happens if you just run phenix.refine to get a map, also take the map from this autobuild run, and look at them along with your model. Is one a lot better than the other?

If you take your best working map and run phenix.fit_loops with this model...how does that do?

All the best,
Tom T

I'm a bit confused about what is going on with my autobuild run.  I solved a structure from anomalous data to 2.7A but many loops are missing.  I ran phaser with the current model and native data that extends to 2.4A and got a solution and started autobuild from there.  I used mostly the default settings and rebuild_in_place=False.  After a pretty short time I realized the run was over and at the bottom of the log I see this:

Cycle 3  R/Rfree=0.28/0.35  Built=488  Placed=467


AutoBuild_build_cycle  AutoBuild  Run 162 Fri Sep  6 14:33:39 2013



Deciding if we should continue...

Recent R change per cycle:  0.0


Ending these build cycles as the recent change in R per cycle has been 

0.0 and the required value of change  is  -0.005

and the R is somewhat acceptable at 0.276670644792

You might consider making one very good model now with: 


phenix.autobuild \

 data=/Users/heather/Desktop/M/AutoBuild_run_162_/overall_best_refine_data.mtz \

 model=/Users/heather/Desktop/M/AutoBuild_run_162_/overall_best.pdb \

 rebuild_in_place=True \

 seq_file=/Users/heather/Desktop/M/m.pir


My full sequence is 325 amino acids so only about 75% is build in.  I am hoping autobuild can help find at least some of these missing residues.  Why would the change in R be zero? What is meant by "You might consider making one very good model now with:"?  I tried running autobuild with these new files and rebuild_in_place=true and get the same type of message.  Is this the best that autobuild can do?  I also ran the phaser solution through refinement and can significantly lower the Rs from 0.26/0.33 to 0.22/0.30.  I appreciate any advice on how best to proceed.  

I am using 1.8.2-1472 if that matters.


Thanks,
Heather
