Error: Ran out of slaves to run tasks
by Xiao-Ping Zhang 16 May '12

16 May '12

Dear Modellers, When I was refining loops for a model in parallel, I asked modeller to generate 9999 models. But modeller stopped at 1245 with the following error. The computer has six cores, modeller uses four of them. The other two cores were free. Thank you for your help. <Slave on localhost> failed (Connection lost to slave <Slave on localhost>: [Errno 104] Connection reset by peer) - removing from <Parallel job [<Slave on localhost>, <Slave on localhost>, <Slave on localhost>, <Slave on localhost>]> <Loop model building task #1.1219> on <Slave on localhost> completed <Loop model building task #1.1217> on <Slave on localhost> completed <Loop model building task #1.1222> on <Slave on localhost> completed <Loop model building task #1.1218> on <Slave on localhost> completed <Loop model building task #1.1223> on <Slave on localhost> completed <Loop model building task #1.1224> on <Slave on localhost> completed <Loop model building task #1.1225> on <Slave on localhost> completed <Loop model building task #1.1226> on <Slave on localhost> completed <Loop model building task #1.1228> on <Slave on localhost> completed <Loop model building task #1.1229> on <Slave on localhost> completed <Slave on localhost> failed (Connection lost to slave <Slave on localhost>: [Errno 104] Connection reset by peer) - removing from <Parallel job [<Slave on localhost>, <Slave on localhost>, <Slave on localhost>, <Slave on localhost>]> <Loop model building task #1.1227> on <Slave on localhost> completed <Loop model building task #1.1230> on <Slave on localhost> completed <Loop model building task #1.1232> on <Slave on localhost> completed <Loop model building task #1.1233> on <Slave on localhost> completed <Loop model building task #1.1234> on <Slave on localhost> completed <Slave on localhost> failed (Connection lost to slave <Slave on localhost>: [Errno 104] Connection reset by peer) - removing from <Parallel job [<Slave on localhost>, <Slave on localhost>, <Slave on localhost>, <Slave on localhost>]> <Loop model building task #1.1235> on <Slave on localhost> completed <Loop model building task #1.1237> on <Slave on localhost> completed <Loop model building task #1.1238> on <Slave on localhost> completed <Loop model building task #1.1239> on <Slave on localhost> completed <Loop model building task #1.1240> on <Slave on localhost> completed <Loop model building task #1.1241> on <Slave on localhost> completed <Loop model building task #1.1242> on <Slave on localhost> completed <Loop model building task #1.1243> on <Slave on localhost> completed <Loop model building task #1.1244> on <Slave on localhost> completed <Loop model building task #1.1245> on <Slave on localhost> completed <Slave on localhost> failed (Connection lost to slave <Slave on localhost>: [Errno 104] Connection reset by peer) - removing from <Parallel job [<Slave on localhost>, <Slave on localhost>, <Slave on localhost>, <Slave on localhost>]> Traceback (most recent call last): File "refine_loop.py", line 41, in <module> a.make() File "/usr/local/lib/python2.7/site-packages/modeller/automodel/loopmodel.py", line 36, in make self.build_seq(self.inimodel, 1) File "/usr/local/lib/python2.7/site-packages/modeller/automodel/loopmodel.py", line 190, in build_seq self.parallel_loop_models(atmsel, ini_model, num, sched) File "/usr/local/lib/python2.7/site-packages/modeller/automodel/loopmodel.py", line 208, in parallel_loop_models self.loop.outputs.extend(job.run_all_tasks()) File "/usr/local/lib/python2.7/site-packages/modeller/parallel/job.py", line 136, in run_all_tasks raise ValueError("Ran out of slaves to run tasks") ValueError: Ran out of slaves to run tasks XP

a question about loop refinement
by mircial＠sjtu.edu.cn 29 Feb '12

29 Feb '12

Dear All: I am a new user of the MODELLER package. I am using the modeller package to refine a loop region of a X-ray crystal structure. I have finished modelling 100 independent structures of that loop and in order to pick out the "good" structures, I need to do cluster analysis on these structures and then compare the representative models from each cluster, am I right? My question is, could MODELLER package do this cluster analysis on the loop structures I got? or I need other softwares to do this analysis? Thanks in advance! R-X Gu

I don't know why you're not seeing any output files - perhaps you're looking in the wrong place for them - but you would see an error message if something went wrong.

How to use MODELLER as an ordinary Python module?
by Desmond Kho 21 Feb '12

21 Feb '12

Hi, I have problem with ' 'import site' failed' when I run plot_profiles.py script. File "plot_profiles.py", line 1, in ? import pylab ImportError: No module named pylab I have all Python2.6, Matplodlib, NumPy, SciPy installed. I read about "Known issues and questions with 9.10", but can't find the instructions for running Modeller with Python. May I know how to run Modeller with pyhton beside the mod9.10 script? Thanks.

energy function scaling factors
by Armin Meier 20 Feb '12

20 Feb '12

Hi Modellers, MODELLER provides a scaling option for energy function terms via e.g.: env.schedule_scale=physical.values(default=1.0, ca_distance=2) In this case, ca_distances are upscaled. If a CA-CA distance is described by a single Gaussian, its restraint is as in http://salilab.org/modeller/manual/node469.html#SECTION001332100000000000000 When scaling CA-CA distances by factor 2, is then "c" (and dc/df) simply multiplied by 2? Thanks for elucidation

Confusion between two models
by hari krishna 19 Feb '12

19 Feb '12

Dear All, I am trying to model a protein containing 859 amino acids. After loop modeling and refinement of two different models, I have doubt in chosing which model for further usage.. Becuase the stereochemical quality was good for one model (85% in favorable region) and for the second model its about 65%. Except this all other parameters like Z-score, energy, residue error plot and DOPE score favors the second model. In this case which one i need to choose. Please help me in this regard. I am attaching the procheck program results.
