Back to Modeller from a long absence, I am faced by a trivial, common issue; "no module named modeller" when running "fill_resid.py", which reads: from modeller import * from modeller.automodel import * # Load the automodel class long.verbose() env = environ() # directories for input atom files env.io.atom_files_directory = ['.', '../atom_files'] a = loopmodel(env, alnfile = 'alignment.ali', knowns = 'my, sequence = 'my_fill') a.starting_model= 1 a.ending_model = 1 a.loop.starting_model = 1 a.loop.ending_model = 2 a.loop.md_level = refine.fast a.make() fill_resid.py, my.pdb, and alignement.ali are in the same dworking directory (My aim is to fill lacking residues in ltwo loops of a protein) The software is correctly installed in debian amd64: francesco@gig64:~$ which mod9.10 /usr/bin/mod9.10 francesco@gig64:~$ Thanks for advice francesco pietra

Phosphoserine residue
by Mike Bramson 30 Jan '12

30 Jan '12

I am just getting started with Modeller, but I need to incorporate a phosphoserine residue, which Modeller cannot seem to handle by default. I have read the FAQ entry on defining new residue types, but it seems quite daunting and I do not have easy access to the needed software. I see that ten years ago, someone ran into the same problem, but as far as I can tell it was never resolved: http://salilab.org/archives/modeller_usage/2002/msg00177.html So I will ask the same question as that poor soul a decade ago: does anyone have the appropriate files for phosphoserine, and would be willing to share? Thanks, Mike Bramson

Need Help getting started
by Henry, Marcia B 30 Jan '12

30 Jan '12

I'm a novice (biochemistry). Very little computer programming, however I can usually teach myself from tutorials. I must be missing something. I can't get through the basic example. I have my sequence in PIR format. Next, going through the example, I opened up the modeller program to get the command screen. I started by typing mod9.10 since I don't have Python installed. c:\Program Files (x86)\Modeller9.10>mod9.10 usage: mod9.10script [...] Next, I attempt to use the command "profile.build()...... and it gives me the error 'profile.build' is not recognized as an internal or external command, operable program or batch file. I have tried to put a name in the parenthesis and I get the same error. Never recognizes the "name" in the parenthesis. I have tried to look at the commands by going to the command directory, but I get the same error regardless of which command I try. Please help! I think I can proceed if I could only start.

how to analyse the output file of align2d.py

mkapsa__637W> No residue topology library is in memory. Better radii would be used if topology.read() is called first. iup2crm_280W> No topology library in memory or assigning a BLK residue. Default CHARMM atom type assigned: N --> N This message is written only for the first such atom. I checked for the template sequence in the pdb_95.pir. but unfortunately I could not find any template sequence for the templates which I selected from the blast result.

If you look further down in the script you will see this: aln.salign(..., feature_weights=weights) i.e. SALIGN is being called with the weights given by the first argument in that 'for' statement above. > What do each of the 6 float constants represent? They're weights - just numbers that multiply each feature's distance matrix. The distance matrix used by SALIGN is simply a linear combination of these. > Also tell me What you exactly mean by feature_weights=[0]*6. I mean exactly what it says - that's elementary Python syntax. [0]*6 is the same as saying [0,0,0,0,0,0]. In other words, all of the features will have zero weight, so SALIGN won't calculate any of them.

Is there a way to it?
by Ashish Runthala 10 Jan '12

Dear Modellers, Is there a key to increase gap penalty scheme for different factors, like residue compatibility, Solvent Accessible Surface Area, depth of residue center from the molecular surface etc. Your help is appreciated.

Modeller is fully functional by itself. (In fact, to the best of my knowledge Sybyl only works with extremely old versions of Modeller anyway - these days Sybyl has been replaced with Discovery Studio.) > Can I use 'Modeller v9.10' with 'Python' or not? Yes, Modeller works with any version of Python between 2.4 and 3.2. > What is difference between use Modeller v9.10 with 'Python' *on > **Linux *and use Modeller v9.10 > with 'Python' *on **Windows Xp and **Windows 7*. Modeller will work in the same way on Linux and Windows. However, if you want to use other Python modules in combination with Modeller, you may find it easier to use Linux.

Dear Sir, I have a question. What commands are required in a Python script, 'evaluate_model.py', to, edit/prepare, 'plot_profiles.py', to, run linear plots of, selected assessment methods (assess.methods) or All , .i.e., GA341 scores' , DOPE-HR scores, normalized DOPE scores, apart from default, DOPE scores and MOLPDF graph plots?
