problem!

Dear users, I am trying to produce a chimeric model for my protein. The first thing I want to do is to check the alignment I have. When I tell Modeller to execute the "check_alignment" command, I get the following message: rdpir___E> alignment sequence not found in PDB file: 1 ./pXXXX.pdb ####################################################################################################################################### The alignment I have is: >P1;pXXXX structureX:pXXXX:.::.::::: CKPMSNFRF-GENHAIMGVAFTWVMALACAAPPLVGWS--RYIPEGMQC-SCGIDYYTPHEETNNESFVIYMFVVHFIIPLIVIFFCYGQLVFTVKEAAAQQQESATTQKAEKEVTRMVIIMVIAFLICWLPYAGVAFYIFTH--------QGSDFGPIFMTIPAFFAKTSAVYNPVIYIMM* >P1;pAveM structure:pAveM:2::211::::: -----------VRWAKLYSLVIWGCTLLLSSPMLV-----------------------------EVFTNMLLNVVGFLLPLSVITFCTMQ---------------------ERRATVLVLVVLLLFIICWLPFQISTFLDTL----------------VITQIASFMAYSNSCLNPLVYVIV* >P1;Ali2 sequence:Ali2:::::::: VKTMSMGRMRGVRWAKLYSLVIWGCTLLLSSPMLVFRTMKEYSDEGHNVTACVISYPSL---IWEVFTNMLLNVVGFLLPLSVITFCTMQIMQVLRNNEMQKFKEIQT---ERRATVLVLVVLLLFIICWLPFQISTFLDTLHRLGILSSCQDERIIDVITQIASFMAYSNSCLNPLVYVIV* ####################################################################################################################################### Perhaps, something is wrong with file names or PDB codes.(I stored the pdb files as pXXXX.pdb) Can somebody help me?

Model Refinement
by Derek Smith 12 Aug '99

12 Aug '99

Dear Modellers I have a manually constructed model protein, which I would like to refine using the MODELLER default schedule. I have attempted this using the protocol based on question 12 in the MODELLER FAQ. However, I find that MODELLER reads the model.ini file, and then extracts restraints from the templates, which are then used in the optimization of the model. I would like to refine my model based only upon my initial conformation. Is this possible do do, and if so, how should I go about it? Thanks in advance, Derek Smith. ************************************************************************* Derek Smith phone: (01904) 432550 Structural Biology Laboratory email: derek(a)yorvic.york.ac.uk Department of Chemistry fax: (01904) 410519 University of York, Heslington, York.

refinement of initial structure
by Derek Smith 09 Aug '99

09 Aug '99

Dear Modellers, I have a manually constructed model and I would like to use the MODELLER optimisation protocol. I have attempted to follow the FAQ question 12, but I find that although MODELLER reads in the 'model.ini' file I give it, it then extracts restraints from the templates to refine the model. Is there a way of presenting MODELLER with a model (minus any other details) and using the program purely as a structure refinement tool? Any help would be appreciated, Derek Smith -- ************************************************************************* Derek Smith phone: (01904) 432550 Structural Biology Laboratory email: derek(a)yorvic.york.ac.uk Department of Chemistry fax: (01904) 410519 University of York, Heslington, York.
