Thank you for the explanations!
I set the job with new parameters. In case it would not be enough I will try
to limit part of the sequence meant for rebuilding or just do loops fitting.
Sincerely,
Tanya

composite model. Each of the 5 models is made by running 5 cycles of
rebuild-in-place, which rebuilds the entire model in overlapping
6-residue segments. This particular process is parallelized only up to the number of models,
so your 32 processors unfortunately don't help you; you are using only 5
of them and getting only 5-fold improvement over one processor. This run seems like it was going fine and was 95% of the way done: AutoBuild_run_1_1_/TEMP0/AutoBuild_run_1_N.log ends with *Copying refined_pdb_in.pdb to composite_model.pdb in
AutoBuild_run_1_/TEMP0
Beginning merge with current best model: refined_pdb_in.pdb
Merging models: composite_model.pdb refine_1.pdb
Refining model: Build_composite_3.pdb
Model: AutoBuild_run_1_/TEMP0/Build_composite_refined_3.pdb
R/Rfree=0.23/0.25 This run doesn't look good: or with error *
TRIED resolve_extra_huge ...but not OK Failed to carry out AutoBuild_build_cycle: but my guess is that if you use a recent "nightly build" of phenix
(available on the web site) the error may go away or at least it *should*
give you a more informative error message if not. You can speed up your job by saying "n_cycle_rebuild_max=1" or =2 (instead
of =5); that will be 5x or 2.5x faster. I am guessing your job could take
about a day on 5 processors (just more than you had), depending on
resolution. All the best,
Tom T Hello! I am trying to use Autobuild wizard and it seems that it takes longer
time
that I expected.
That's why I have next questions: 1. What is "usual" time range estimate for Autobuild run with default
parameters if my model has 7 chains with 284 aa in each?
(if I'm running Autobuild on a single machine it does not finish in 3
days
or on cluster with usage of 32 processors - in 24 hours) 2. Do I use phenix comman correctly for using several machines at once? I used /phenix-1.4-89, command line
*phenix.autobuild data=e239a.hkl seq_file=seq.dat model=model.pdb
nproc=32* In 24 hrs, which is my limit on cluster time, I get next things -
AutoBuild_run_1_1_/AutoBuild_run_1_1.log ends with *Setting up to build 5 models to be combined into final model #1
NOTE: input model will be rebuilt in place: nothing will be added or
deleted.
