Upper limit distance restraint
by Miha Pavsic 03 Dec '03

03 Dec '03

Hello Modeller users, I am looking for a way to specify upper limit distance restraint between CA atoms of two residues (eg., max 10 A between CA:25 and CA:187). Can someone please give me an example of doing this? Regards, Miha Pavsic *** Miha Pavsic, PhD Student Josef Stefan Institute Dept. of Biochemistry and Molecular Biology Jamova 39, SI-1000 Ljubljana, Slovenia

Re: [modeller_usage] malign3d will not align multiple structures
by Mark Daniels 01 Dec '03

01 Dec '03

Hello Oliver- Thank you for the reply. MALIGN3D does not require an alignment file if the structural models have a 1:1 sequence correspondence. In my case I am aligning five models of the same protein. I figured out what the problem was by looking at the .top files in the examples/tutorial-model folder of modeller6v2. As it turns out, I have to add the command SET ALIGN_CODES = 'atip' 'atip' 'atip' 'atip' 'atip' with which MALIGN3D properly loads the five model atip.Bxxx files. The Sanchez and Sali Methods in Molecular Biology article does not mention this (and neither does the manual).

malign3d will not align multiple structures
by Mark Daniels 01 Dec '03

01 Dec '03

Hello all- I'm trying to run malign3d to align multiple models but the routine only 'sees' the first structure and does nothing. I'm using the malign3d.top file format described in the Sanchez and Sali 2000 Methods in Molecular Biology article: SET OUTPUT_CONTROL = 1 1 1 1 2 SET MAXRES = 700 SET ATOM_FILES = 'atip.B99990001' 'atip.B99990002' ; 'atip.B99990003' 'atip.B99990004' 'atip.B99990005' SET WRITE_FIT = on MALIGN3D All the atip.Bxxxx files contain a reasonable structure. Running the malign3d.top routine shown above fails to produce any .fit files and shows the following error: openf5__224_> Open 11 OLD SEQUENTIAL atip.B99990001 malign3_327W> Only one structure; nothing done. Would anyone be able to advise me on what I'm missing here or doing wrong? Thanks in advance- Mark Daniels The Scripps Research Institute

MacOS X Modeller 6v2
by Jack Howarth 20 Nov '03

20 Nov '03

Hello, The maintainer of the MacOS X version of Modeller 6.0 may want to consider installing fink 0.6.2 (from fink.sourceforge.net) and 'fink install' the gcc 3.4 g77 compiler to do the next build of Modeller 6.0 under Panther. While the gcc 3.4 g77 compiler isn't as agressive in optimization as the IBM XL Fortran for MacOS X compiler, it does a much better job than before (if used at -O3). This now enables the DFA ppc support in the compiler. I just mention this because the Absoft build of modeller seems a bit sluggish. Unless you have the very latest Absoft MacOSX compilers they might not even generate code as fast as the g77 from gcc 3.4. Otherwise perhaps you need a much higher optimization level setting with the Absoft compiler than you are currently using. Jack Howarth ps If you use g77 3.4 and find that you get compilation error at -O3 you might selectively add -fno-globals to those specific files. The use of -fno-globals on all the source files will impact the performance of the generated code because it disables higher order optimizations. So that should be avoided. ------------------------------------------------------------------------------ Jack W.

problems with heteroatoms
by Knoll, Michael 19 Nov '03

19 Nov '03

Hi modellers, I have some problems with including heteroatoms in my models. In my pdb-template file there is an HETATM entry at the end (in this case it´s CA). I've switched the HETATM_IO option on in the modeller top-file. Now if I add the residue type number 3 at the end of my alignment, it looks like this : >P1;755 structure:755: : : : : : : : . . . THANRLKLAGV3* >P1;5 sequence:5: : : : : : : : . . . THANRLLLAGV3* This additional entry leads to models which have the correct heteroatom modelled. Now I want to change the residue type number 3 into a wildcard so that in other cases every possible heteroatom could be modelled without looking at the template pdb-file. If I place . instead of 3, the modeller log-file shows following error-massage : Alignment sequence not found in PDB file: Can you tell me if it´s possible to use such a wildcard, or do I have to select the right residue type number for each HETATM-type. Thanks in advance, Michael --

Modeling Multidomain proteins
by Tjaart de Beer 18 Nov '03

Hi there I would like to model a multidomain protein but when I follow the instructions given in the manual I only only get a model based on the first structure in my alignment file. It totally ignores the second structure. There is no overlap between the domains. The top file and alignment file is attached. Can anyone help?

modeling a dimer
by Rao, Guru 14 Nov '03

14 Nov '03

Hi: I am working with a protein which we have characterized to be a dimer. Homologous proteins are also dimers and the 3D structures are of the dimeric forms. In these proteins, the amino acid sequence of the dimer is represented as A and B chains. Can I model my protein as a dimer by arranging my sequence as A and B chains with a " | " in between? Would appreciate some thoughts.
