<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hi Matt,<div><br></div><div>I think that your run is the "one-good-model' protocol, in which case there are by default 5 runs of rebuilding the model and they are then combined into a single model. Autobuild one-good-model does take a long time, but this seems a bit longer than usual. This could be due to the simulated annealing that you are doing...</div><div><br></div><div>I had a look at our standard structures in the PHENIX structure library and pulled out some examples to give you some examples of how long the procedure can take. These do not include simulated annealing:</div><div><br></div><div><br></div><div>rh-dehalogenase rebuilds 290 residues at 2.8 A and takes 3 hours (starting R/Rfree = 0.17/0.23 ; final = 0.15/0.21)</div><div><br></div><div>a2u-globulin at 2.4 A, four chains each with 157 residues, takes 13 hours to run rebuild-in-place (R/Rfree= 0.31/0.35 starting; 0.20/0.24 final)</div><div><br></div><div>apoferritin at 2.0 A; 173 residues; takes 26 hours (R/Rfree= 0.23/0.26 starting; 0.22/0.25 final)</div><div><br></div><div><br></div><div>So overall I'd say your case is on the long side but is probably doing what it is supposed to do. To check it out, have a look at your log file</div><div><br></div><div>AutoBuild_run_1_/TEMP0/AutoBuild_run_1_/AutoBuild_run_1_1.log </div><div><br></div><div>which is the first of 5 rebuild-in-place runs on your model. (AutoBuild runs itself in the TEMP0 subdirectory, yielding all the AutoBuild_run_1_ runs there, then the resulting models get combined into a final model which goes in top AutoBuild_run_1_/overall_best.pdb). </div><div><br></div><div>See if the first run has improved the model and the R/Rfree...Your starting R/Rfree before rebuilding will look like this:</div><div><br></div><div>Refining model: unrefined.pdb_1</div><div>Model: refine.pdb_1 R/Rfree=0.31/0.35</div><div><br></div><div>..and the end of the file will look like this:</div><div><br></div><div><br></div><div><div><div>SOLUTION CYCLE R RFREE BUILT PLACED</div><div> 1 2 0.22 0.26 573 0</div><div> 2 3 0.21 0.24 577 0</div><div> 3 4 0.21 0.24 598 0</div><div><br></div><div>so in this case (a2u-globulin) this single rebuild-in-place works well...then combining the 5 models from 5 such runs gives the final R/Rfree of 0.20/0.24 I mention above.</div><div><br></div><div>I hope that helps!</div><div>All the best,</div><div>Tom T</div><div><br></div><div><br></div></div><div><br></div></div><div><br><div> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><div><div><div><div><br>Thomas C.

I am not sure if it runs properly since this is my first time to run this module....it took like almost a day to just finish the run_1 (there should be five runs by default?), which means it will take me another 4 days to finish the whole thing. My protein has around 350 residues and in the refined model, I have omitted some loops (about 80 residues) because I cannot see the electron density of those regions. I have put the seq.dat file with the full sequence (~350 residues) and the commands "place_water=Yes" and "s_annealing=True". The resolution is 2.4 A.
