Making the symlink is easy: assuming you already have the RPM installed, just do (as root, and all on one line) ln -sf /usr/lib/modeller9v1/modlib/modeller /usr/lib/python2.5/site-packages/ Ben Webb, Modeller Caretaker -- modeller-care(a)salilab.org http://www.salilab.org/modeller/ Modeller mail list: http://salilab.org/mailman/listinfo/modeller_usage

problems modeling a multimer
by Douglas Kojetin 15 May '07

15 May '07

Hi All, I would like create a hexameric model using a target sequence and a hexameric PDB template. I am trying to create an alignment using input files that have the \ character to separate the chains. Example: >P1;target sequence:target:::::::0.00: 0.00 AAAAA\ BBBBB\ CCCCC\ DDDDD\ EEEEE\ FFFFF* I'm using the align2d.py example, as detailed in tutorial 2. My input PDB file has six chains (A-F). My align2d.py file is as follows: """ align2d.py START from modeller import * log.verbose() env = environ() aln = alignment(env) mdl = model(env, file='PDBfile_hexamer', model_segment= ('FIRST:A','LAST:F')) aln.append_model(mdl, align_codes='PDBfile_hexamer', atom_files='PDBfile_hexamer.pdb') aln.append(file='target_hexamer.ali', align_codes='target') aln.align2d() aln.write(file='target_hexamer-PDBfile_hexamer.ali', alignment_format='PIR') aln.write(file='target_hexamer-PDBfile_hexamer.pap', alignment_format='PAP') """align2d.py END Using modeller9v1 (linux RPM), I started the above calculation (python align2d.py), but it has not finished after 20 hours (and is still going; 100% CPU and 22.6% memory usage out of 3 GB total, according to 'top'). Although I used log.verbose(), there is very little output in the associated log (see below). Any ideas?

The alignment sequence must match that from the atom file exactly. Another possibility is that some residues in the atom file are missing, perhaps because they could not be resolved experimentally. (Note that Modeller reads only the ATOM and HETATM records in PDB, NOT the SEQRES records.) In this case, simply replace the section of your alignment corresponding to these missing residues with gaps. read_te_288W> Protein not accepted: 2 1XEFA rdabrk__337E> Structure not read in (please consult the log file for more details): Please help.

Optimizing the Helix strain in the model?
by Ngo Duc Tri 14 May '07

14 May '07

Dear Modeller users, I can learn from the Interative Example (Modeller Tutorial) that I can increase the accuracy of the helix strain by removing or transfering the gap to the begining or ending ot the helix. However If my alignment don't have the gap in the helix region and the alignment score seem maximum. I would like to know how I can do in this situation because optimizing the loop cannot be applied in this. This region is in the transmembrane of a membrane protein. Thank you very much for all of your advices, My best regards, TriNgo

loop to connect two domain
by Jayapal, Prabha 14 May '07

14 May '07

Dear Modeller: I am new to protein modelling. I want to connect two domains by a loop containing 16 residues. I am having templates for both the domains and not for the loop. I have tried some of the loop modelling techniques but unsuccessful. Can anybody help me with this situation? Thanks in advance. Cheers J.Prabha

hey, i'm new to modeller. I can use modeller and and get homology models of proteins but when it comes to writing the superposed pdb's (the x_fit.pdb's) it comes up with an error and doesn't... i've included the .top, .ali, and .pdb as well as a screenie of the error. any help would be greatly appreciated. thanks heaps -mike

Modeller as webservice (WSDL)

L.S, I'm currently using modeller as standalone application but 'm planning to set up a more automated setup. To do this i wanted to use modeller as a webservice (WSDL) in Taverna. Has any body ever created a wrapper for this? In the archives no reference to wsdl found :-( Thanx in advance Kees-Jan

[Fwd: Cannot generate the plot of DOPE?]
by Modeller Caretaker 08 May '07

08 May '07

-------- Original Message -------- Subject: Cannot generate the plot of DOPE? Date: Wed, 9 May 2007 02:03:18 +0900 From: Ngo Duc Tri <ngoductri(a)gmail.com> To: modeller-care(a)salilab.org Dear Modeller users, I finished modelling my protein and doing the evaluation step. I run the file evaluate_model.py to calculate the DOPE score of my model. I got DOPE score : -39521.605469 and there was no error in the log file. I use this profile file to generate the DOPE plot using GNUPLOT but this program show a strange line. Actually It just show the position of my aminoacid but no DOPE score for each. I run the GNUPLOT and used the command: plot ' myprotein.profile' I want to ask you If it's the error of GNUPLOT or my profile file? And how can i fix it to show the actual DOPE score for each residues. Thank you very much for your comments, Best regards, TriNgo Sungkyunkwan University

Ubuntu installation issue
by Christian Meesters 07 May '07

07 May '07

Hi, I just installed Ubuntu 7.04 on one machine and tried to get modeller running. I tried an installation from source as well as using the rpm. Actually modeller itself is installed, but the python module is not available. The only python-installation I have is 2.5 and I would rather not work with 2.3. Last time I installed modeller I had the module running with python 2.4, so I guess running with 2.5 should be possible, too. (There are no .so-files I could get into the python path manually.) Did anyone try to install modeller on Ubuntu/Debian or alike and has a hint for me? TIA Christian
