pdb code
by si yang 21 Dec '11

21 Dec '11

Good day to all, I have encountered a small problem during model.evaluation, the normalized dope.py requires to load a built model as indicated below: # Read a model previously generated by Modeller's automodel class mdl = complete_pdb(env, '../atom_files/xxx.pdb' right now the xxx should be replaced by the pdb code such as 1fdx, however my protein sequence is not yet deposited into PDB, thus it does not has pdb code, i just name it as MBL.B99990003.pdb (for example) after the atom_files: mdl = complete_pdb(env, '../atom_files/MBL.B99990001.pdb' However, the error stated that the pdb file is not a valid file, so do any expert provide suggestion to solve this problem?? Your response is appreciated.... Regards, Zhao Yang Institute of Bioscience UPM, 43400, Serdang Selangor, Malaysia

Re: [modeller_usage] Who is best among these to search templates?

First, as to the differences between CS-Blast and HHpred, please consult the two links below: http://lmgtfy.com/?q=hhpred+wiki&l=1 http://lmgtfy.com/?q=cs-blast+wiki&l=1 There is no absolute way to answer your second question. CS-BLAST provides only a starting (and context-dependent) checkpoint for BLAST or PSI-BLAST, from which those programs usually find more homologues than when they start from a single protein sequence. HHpred, however, further uses all sequences found by PSI-BLAST, aligns them and makes hidden Markov models, and then performs HMM-HMM search which is at present the most sensitive way to detect homology. The problem with HHpred is that even though it is most sensitive, it doesn't contain all PDBs in its library, so PSI-BLAST jump-started by CS-BLAST may still end up finding a better alignment simply because, unlike HHpred, it searches against all PDB sequences out there. Publications about both methods and their respective web pages offer clear descriptions of what each approach can do. Shouldn't be too hard to find them using PubMed.

Who is best among these to search templates?

Respected Sir, First of all sorry for a bit unrelated question to MODELLER, but please tell me, what is the difference between 1. CS-BLAST 2. HHpred Who is the best of these two at searching most reliable homologoua templates (PDBs) for a target sequence? I am not able to find differences between these two. Thank you Sir and Sincerely, Ashish Ashish Runthala, Lecturer, Structural Biology Cell, Biological Sciences Group, BITS, Pilani Rajasthan, INDIA

What is the difference in salign_multiple_struc among these 2 conditions
by Ashish Runthala 14 Dec '11

14 Dec '11

Dear Modellers, I am a bit confused about the utility of auto_overhang=true usage in salign_multiple_struc.py for MSA computation. Even if i don't use this line, result comes the same as _fit files are generated. Same is the case when i don't use this line before computing the alignment writing the result. Alignment files generated are also same in both these cases, both including the sub-optimal alignments. Please explain me this difference. Is it that auto_overhang option is integrated in salign_multiple_struc.py and is employed automatically without being called for it. Thanks, Ashish Ashish Runthala, Lecturer, Structural Biology Cell, Biological Sciences Group, BITS, Pilani Rajasthan, INDIA

What environment variables did you set?

No, we only support the standard version of Python (/usr/bin/python) shipped with OS X. > I currently use it, and I cant import modeller We distribute all the SWIG inputs to build the Modeller Python extension, in src/swig/, so in principle you can build it for a newer version of Python if you like (the rest of the Modeller Python code will already work with Python 3).

windows 7, modeller 9.10 and python 2.6.6
by Ludovic Autin 09 Dec '11

09 Dec '11

Hi, until I never add any problem with MODELLER, which is a really nice software. I recently encounter a problem on windows 7-64bits. Python2.6.6 32bits is installed as well as a python2.7 64bits version. Modeller 9v10 is installed and seem to work. The problem is accessing modeller from Python 2.6.6. After setting all the environment properly for modeller, inside python I got this error : import _modeller ImportError : DLL load failed: La procedure specifie est introuvable (sorry for the french, ie file not found) Its seems that there is some library that cant be found. I used dependancy walker to see what was the dependancy of _modlib.so in modlib/python2.6/ and it appear to be libmodlib.dll that is in the bin directory... I try to add the bin directory ion the path but didnt solve the problem... Any idea what could cause this confusion/problem ?? what should I do ?? Thanks a lot in advance, any help is welcome Ludovic

have problem running modeller 9.10
by Yu Li 04 Dec '11

04 Dec '11

Hi, I am trying to use modeller to model a chimera protein. I am going through the online tutorial and documentations. However I found that I cannot run modeller on my computer. I have a windows 7 machine with python 2.7 installed. The error message I got when I type mod9.10 model-default.py in command window is: 'import site' failed; use -v for traceback Cannot open logfile model-default.log: Permission denied. I am in the same fold as the model-default.py file. Anyone know what is going on? Many many thanks.
