Installation problems Windows XP
by Simon P Gough 21 Oct '02

Dear Modellers & Bozidar & team (Sending against think it got lost) Thanks for sending the key for the program . As a computer illiterate I find it hard to understand how to install modeller under Windows XP (1.7GHz Athlon processor, 1.5mB RAM) using the instructions given on the Web site. After unpacking the zip file to C:\ Modeller6v2 Then I setenv "KEY_MODELLER6v2" to "E-mailed value" setenv MODINSTALL6v2 C:\modeller6v2 Why ? setenv LIBS_LIB6v2 $MODINSTALL6v2/models.lib (I guessed it might be this one ??) set path=($path $MODINSTALL6v2) OK -left out the non-existent "bin" directory ?? set limit stacksize unlimited Not accepted by program -not done I could not then run the program with the command "Install" or "modeller6v2.exe" Or "make install" Could anyone please help me . It would be great to be able to use this program. Thanks! Simon Gough

Is this a bug?

Dear Modellers, When running the compare.log script on the TvLDH example I obtained a qualitatively different aliignment than the "known" which I downloaded from the web-site.

Bug reported in previous message - Description and Workaround
by Richard Friedman 21 Oct '02

21 Oct '02

Dear Modeller Team, I am running Modeller 6v2 on a Dec Alpha. I was not able to run the compare script for the TvLDH tutorial successfully with the script and filenamse provided. The directory in which I attempted this is encoded in the preceeding e-mail message. As far as I can see, the program is reading the input pdb file name incorrectly. For example, 1bmdA is read as 1bmd. As a result the job does not run. I found however when I copied the pdb files to ones with shorter names i.e. copied 1bmdA.pdb to 1bmd.pdb the script ran well. Please excuse me if this apparent bug is really due to an error on my part, but if it is, please let me know how. Thanks and best wishes, Rich -------------------------------------------------------------- Richard A.

Question on 1fdx example
by Richard Friedman 18 Oct '02

18 Oct '02

Fellow Modellers, I ran the first example in the Modeller tutorial, 1fdx, and I got several restraint violations in the final structure. I ran the diagnostics, and I dod not receive any error messages. Is this as it should be? Is there anywhere in which one can obtain a standard 1fdx run that can be used as a "known"? I know that, based upon faq #23, interpreting restraint violations is something of an art. I am asking to make sure that I ran the program correctly, and that the program is running as it should be. My violated restraints are: Summary of the restraint violations: NUM ... number of restraints. NUMVI ... number of restraints with RVIOL > VIOL_REPORT_CUT[i]. RVIOL ... relative difference from the best value. NUMVP ... number of restraints with -Ln(pdf) > VIOL_REPORT_CUT2[i]. RMS_1 ... RMS(feature, minimally_violated_basis_restraint, NUMB). RMS_2 ...

modeller usage
by Somanadh Babu 17 Oct '02

17 Oct '02

Hello, I am a begiiner with modeller. I am using modeller6v2. I tried running modeller with model-default.top as the input file and from what I knew,a '.atm' file has to be generated after the process. I am working in LINUX. The process stopped after a couple of seconds and the message STOP was thrown. No ".atm" file was generated. How do I proceed further? sincerely, somanadh

Problems reading in pdb template file

Hi, I'm quite new to using MODELLER and am having difficulties reading in a pdb template file.

problem with SET MD_LEVEL

I don't remember that other user had commented that we must to set something special (a variable or so) to run MD in our models. Any hint will be very helpful Thanks in advance Frank Alarcon www.lncc.br

Dear modellers: I have modelled a molecule successfully using modeller. This molecule forms dimers, probably very similar as it occurs with the template molecule, and I would like to optimize my model to improve the dimerization surface and intersubunit contacts. Which would be the best strategy to do it so?. How can I restrain changes in one subunit to be exactly modelled in the other subunit?. Many thanks in advance for your suggestions, Santiago *********************************************** Santiago Ramón-Maiques Instituto de Biomedicina de Valencia Consejo Superior de Investigaciones Científicas C/ Jaime Roig, 11 46010 Valencia, Spain ***********************************************
