will someone please help me. I would like to use Modeller to align the structures of 41 protein sequences to 1E1E, which has a structure. I have PDB files of all 42 proteins, and I have aligned all of them using ClustalW. I have altered the alignment to the PIR format, as specified. I am trying to perform an initial family alignment of all structures and sequences, as specified in 1.7.2, yet MALIGN3D does not work. It will not read in the structural information. I am very confused by everything and would greatly appreciate if someone could help me go through the process of aligning protein sequences to a known structure.

Hi all, I wanted to remind you once again that if you submit an email to the modeller_usage list it MUST be from the same email account a the one you used to sign up yourself from, otherwise your submission will get bounced back. Happy modeling, Bozidar

Re: Modeller for Mac OS X

Hi Dhaval, Although it shouldn't be, it might be ;-) Make sure you are in tcsh. If that doesn't help I would suspect it's Jaguar. I have compiled this version of MODELLER on my PowerBook running 10.1.5.

Hi modellers.. Today, i met this message from modeller....but i can not understand why this occurs.... i retrived 3TAT.pdb file from www.pdb.org and prepared ate1.ali file from ClustalW in PIR format... The related files and log file are below.... why modeller give me the 'sequence not read in' message??

Hi modellers.. When i run modeller6v1, i met 'sequence not read in' message in .log file... There are not any problems in .ali file.... If the known sequence residue number is different with its residue number in PDB file, how can i edit the PDB file ? e.g. .ali file MFMKF...... .pdb file M 5 F 6 M 10 ...... Regard.. Byung-Kwan Cho

2 problems - HETATM_IO and strange log (fwd)
by Frank J A B 02 Sep '02

02 Sep '02

Dear All I'm facing to problems with modeller. In the FAQ's question #16 there is an explanation on how to use hetero atoms in modelling adding the line HETATM_IO = on in the top script. There is also a comment (confuse in my opinion) about the use of w for water and . for other atoms in the alignment that still remains unsolved to me. In my case I'm trying to use FAD in the modelling. I can't wonder how to edit the alignment to include this Ws and .s Check the example given. INCLUDE SET ALIGNMENT_FILE = 'align1.ali', KNOWNS='templ1', SEQUENCE='targ1' SET HETATM_IO = on, WATER_IO = on CALL ROUTINE = 'model' The alignment file: >P1;templ1 structureX:templ1:1::10:: FAYVI/.wwww* >P1;targ1 sequence:targ1:1::8:: -GWIV/.ww-w* Need I to repeat the entire alignment (template/target) inside the same .pir file, but now only with signs like - , ., w , #) where the .s/Ws positions correpond to those aa that make contact with the HETATM in the structure/template ? The second question is about my log file. I'm habituated to use regularly Modeller since version 4 but suddenly the job was finished abruptly with this : MODELLER 6v2, 17 Feb 2002 PROTEIN STRUCTURE MODELLING BY SATISFACTION OF SPATIAL RESTRAINTS assgn___544E> Variable name not recognized: /pipe1/databases/pdb/uncompressed_files/pdb1hci.ent Command line: INCLUDE assgn___525E> Error in TOP variable assignment. recover____E> ERROR_STATUS >= STOP_ON_ERROR: 1 1 Is this some kind of bug or a user error ? I'm sure that the files are typed correctly (case-sensitive) and the folder where the job is started has all the files in it. Any hint asap will be very much appreciated. Thanks in advance brgds Frank Alarcon LNCC - Brasil www.lncc.br
