When having multiple templates and several unwanted regions this procedure becomes very tedious.

Hi all, suppose I have the following simple "dummy" py-modeller script: from modeller import * from modeller.automodel import * log.verbose() env = environ() env.io.atom_files_directory = '<path to pdb>' # containing d1f0la3.pdb a = automodel(env, alnfile = '<my_pir_file.pir>', # alignment filename knowns = 'd1f0la3', # codes of the templates sequence ='d1f0la3') # code of the target a.starting_model = 1 a.ending_model = 3 a.make() and the corresponding pir file: >P1;d1f0la3 sequence:d1f0la3: 1: : 180: :f.1.2.1 (A;201-380) Diphtheria toxin, middle domain {Corynebacterium diphtheriae [TaxId; 1717]} PDB; d1ddta3 d1p3gb_ d1p3gf_ d1p3pb_ d1p3pf_ d1p3bf_ d1p3ib_: : 0.00: 0.00 CINLDWDVIRDKTKTKIESLKEHGPIKNKMSESPNKTVSEEKAKQYLEEFHQTALEHPELSELKTVTGTNPVFAGANYAAWAVNVAQVIDSETADNLEKT TAALSILPGIGSVMGIADGAVHHNTEEIVAQSIALSSLMVAQAIPLVGELVDIGFAAYNFVESIINLFQVVHNSYNRPAY* >P1;d1f0la3 structureX:d1f0la3: :A: :A:f.1.2.1 (A201-380) Diphtheria toxin, middle domain {Corynebacterium diphtheriae [TaxId 1717]} PDB d1ddta3 d1p3gb_ d1p3gf_ d1p3pb_ d1p3pf_ d1p3bf_ d1p3ib_:Corynebacterium diphtheriae [TaxId; 1717]:-1.00:-1.00 CINLDWDVIRDKTKTKIESLKEHGPIKNKMSESPNKTVSEEKAKQYLEEFHQTALEHPELSELKTVTGTNPVFAGANYAAWAVNVAQVIDSETADNLEKT TAALSILPGIGSVMGIADGAVHHNTEEIVAQSIALSSLMVAQAIPLVGEL--IGFAAYNFVESIINLFQVVHNSYNRPAY* Then I get the following error when executing the script: Traceback (most recent call last): File "/cluster/tmp/armin/test/d1f0la3_d1f0la3_1.py", line 14, in <module> a.make() File "/cluster/bioprogs/modeller9v5_RSR/modlib/modeller/automodel/automodel.py", line 98, in make self.homcsr(exit_stage) File "/cluster/bioprogs/modeller9v5_RSR/modlib/modeller/automodel/automodel.py", line 425, in homcsr self.check_alignment(aln) File "/cluster/bioprogs/modeller9v5_RSR/modlib/modeller/automodel/automodel.py", line 407, in check_alignment aln.check() File "/cluster/bioprogs/modeller9v5_RSR/modlib/modeller/alignment.py", line 191, in check self.check_structure_structure(io=io) File "/cluster/bioprogs/modeller9v5_RSR/modlib/modeller/alignment.py", line 200, in check_structure_structure return f(self.modpt, io.modpt, self.env.libs.modpt, eqvdst) _modeller.ModellerError: check_a_282E> Unable to read structural information for alignment sequence: 1 d1f0la3 This command requires structures.

initial model
by sdh 17 Aug '10

17 Aug '10

Hello All, I want to model a multi-domain protein. Thus, I aligned manually all templates (corresponding to the individual domains) and used them as an input for Modeller. (Note that the templates overlap only over few residues.) However, when I compared the initial model (.ini) to the aligned templates, I saw that Modeller did something more than just transferring the coordinates from the templates. Namely, the relative orientation of domains is not as in my structural alignment. Is thee any way to force Modeller to use exactly the input coordinates? initial_malign3d is set to False and default transfer_xyz() is used Thanks for help! Staszek

Parallel task using sge_pe_job()
by Charles Xue 28 Jul '10

28 Jul '10

Hello, I am attempting to run MODELLER in parallel on a cluster with multiple nodes. The script I used is below: from modeller import * from modeller.parallel import * from modeller.automodel import * log.verbose() j = sge_pe_job() env = environ() a = automodel(env, alnfile='2NT2-mult.ali', knowns=('1m3gA','2wgpA','2hxpA'), sequence='2NT2', assess_methods=(assess.DOPE, assess.GA341)) a.starting_model = 1 a.ending_model = 25 a.use_parallel_job(j) a.make() However, once I submit the job (using the parallel environment mpich), the job runs on the master node fine but fails on all the slave nodes. The error is also ambiguous: within the slave1 output file (identical for all other output files except the slave0 one which runs fine): error: executing task of job 76003 failed: Thanks in advance for the help! -Charles Xue

Re: [modeller_usage] have you solved the problem with installation under Windows XP

The Modeller shortcut in the Start menu simply runs command.com /E:8192 /K "C:\Program Files\Modeller9v8\bin\modenv.bat" i.e. it starts a command prompt and runs that batch file to set up the environment so that Modeller will work. (If you run a regular command prompt, it won't have the paths set up properly, and Modeller won't work.) I don't know why the Start menu shortcut isn't being installed on your system - although you have to run the installer as an admin user in order for it to do that (it should warn you if you don't) - but you can make your own shortcut to Modeller in this case.

I can't find anything with *batch* in the search. The Modeller batch file is called modenv.bat and lives in the 'bin' directory under whichever directory you installed Modeller in (C:\Program Files\Modeller9v8 by default). On a successful install, it looks like: @echo off set MODINSTALL9v8=C:\Program Files\Modeller9v8 set PYTHONPATH=C:\Program Files\Modeller9v8\modlib; set LIB_ASGL=C:\Program Files\Modeller9v8\asgl set BIN_ASGL=C:\Program Files\Modeller9v8\bin set PATH=%MODINSTALL9v8%\bin;%PATH% cd C:\Program Files\Modeller9v8 echo You can find many useful example scripts in the echo examples\automodel directory. echo Type 'mod9v8' to run Modeller. What does yours look like? Ben Webb, Modeller Caretaker -- modeller-care(a)salilab.org http://www.salilab.org/modeller/ Modeller mail list: http://salilab.org/mailman/listinfo/modeller_usage

have you solved the problem with installation under Windows XP
by Andrew Voronkov 20 Jul '10

20 Jul '10

Dear Modeller administration, there is definitely a problem with installation of Modeller uinder windows XP 64 bit. I have installed it on different PCs in different places, I don't get icon in Start menu and when I run it using command line there is an error message about environment which is not set properly. I don't know if there is such a problem with Windows XP 32 bit as well, but this is definitely a bug with Windows XP 64 bit. If you have such a system or any of users have it - please test Mod9v8 and confirm that it doesn't install properly. Sincerely yours, Andrew
