It's hard to say for sure what your problem is without seeing all of your input files, but it looks like you haven't turned on env.io.hetatm, so I don't think you should be seeing ligands in either your regular models or your loop models. You can see the restraints that loopmodel builds by looking at the loop_restraints() method in the modlib/modeller/automodel/loopmodel.py file. By default it builds stereochemical, phi/psi, and dihedral restraints, but not the ligand-protein restraints that automodel does. You could easily fix this to restrain ligands by overriding the special_restraints() method and calling automodel.nonstd_restraints() from there. Note however that the ligand-protein restraints may be too strong to allow your loop to explore much conformational space, so it may make sense to use weaker or fewer restraints here. > def special_restraints(self, aln): > rsr = self.restraints > rsr.add(atom_ids=('CA:189', 'CA:372'), > restraint_parameters=(3, 1, 1, 27, 2, 2, 0, 10.0, 0.1)) > rsr.add(atom_ids=('CA:189', 'CA:393'), > restraint_parameters=(3, 1, 1, 27, 2, 2, 0, 10.0, 0.1)) > rsr.add(atom_ids=('CA:372', 'CA:393'), > restraint_parameters=(3, 1, 1, 27, 2, 2, 0, 10.0, 0.1)) Note that this way of specifying restraints is error prone and deprecated.

restraints from multiple templates
by Mathew Smith 16 Aug '07

16 Aug '07

I was wondering how modeller uses the structural information of multiple templates. Are all aligned residues of all the templates used to create the restraints and are they weighted in any way e.g. by sequence identity of template to target or by residue type (exact matches weighted more than disimilar aa's)? Also how can I alter these things so that I can tailor the restraints that I use depending on in/dels and sequence similarity etc?

Reg. Generating profile plot using GNUPLOt
by saravanan 16 Aug '07

16 Aug '07

Query regarding visualizing profile in GNUPLOT We run the evaluate_model.py which implements mdl.assess_dope function in modeller8v2. We got the DOPE score. Now we want to generate the PLOT using GNUPLOT with the output of the script. We tried in GNUPLOT, we just got a diagonal line but not like presented in the tutorial. the script looks like: from modeller import* from modeller.automodel import* log.verbose() env=environ() env.libs.topology.read(file='$(LIB)/top_heav.lib') env.libs.parameters.read(file='$(LIB)/par.lib') #env.io.atom_files_directory='./:../atom_files' mdl=model(env) mdl.read(file='1fdx.B999900001.pdb') aln=alignment(env) code="1fdx_my" aln.append_model(mdl,atom_files='1fdx.B999900001.pdb',align_codes=code) aln.append_model(mdl,atom_files='1fdx.B999900001.pdb',align_codes=code+'-ini') mdl.generate_topology(aln,sequence=code+'-ini') mdl.transfer_xyz(aln) mdl.assess_dope(output='ENERGY_PROFILE REPORT',file='1fdx_my.profile', normalize_profile=True,smoothing_window=15) Looking forward for reply -P.Saravanan ____________________________________________________________________________________ Sick sense of humor?

modeller 9.2: spaghetti effect with multiple templates
by Raik Gruenberg 10 Aug '07

10 Aug '07

Hi modellers, already a while ago I have noticed that modeller tends to produce what I would call spaghetti proteins (containing knots and other fancy structures) when it is supplied with multiple templates that are far from the target (35 % or less) and also quite diverse among each other. However, Modeller 9 seems to suffer more from this effect than the previous versions: One of our test cases uses 10 templates with between 86% and 31% sequence similarity to the target. I know that this is not the optimal strategy (especially after reading this paper: http://bioinformatics.oxfordjournals.org/cgi/content/abstract/btm262v1 ) but modeller 8.2 still performed quite well and all 10 models had good topology (close to the 86% template) and secondary structure. However, I now re-run our test with modeller 9.1, using the identical alignment (T-Coffee) and the same input file (below) and the result looks much worse. Most among the 10 generated models show a messed up (swaped) topology, many have knots and the different models are generally more diverse. So to what extend differs the multiple-template treatment of Modeller 9 from previous versions? Do I need to use different parameters for multi-template modeling in the new version? Or is the general default modeling protocol different now? So here is our (old-style) input file: INCLUDE SET OUTPUT_CONTROL = 1 1 1 1 1 SET ALNFILE = 'final.pir_aln' SET KNOWNS = '1K2H_A' '1M31_A' '1J55_A' '1KSO_A' '1MQ1_A' '1MWN_A' '1MHO_' '1NSH_A' '1K8U_A' '1DT7_A' SET SEQUENCE = 'target' # code of the target SET ATOM_FILES_DIRECTORY = '../templates/modeller/' SET STARTING_MODEL= 1 # index of the first model SET ENDING_MODEL = 10 # index of the last model CALL ROUTINE = 'model' I am attaching a typical result of modeller 8 and one of modeller 9 for comparison. Thanks in advance for any comments! Best regards, Raik
