Hi modllers, I am trying to use win version of modeller. I have two problems: 1. Although example files run fine, I get this error message with my proteins: check_337E>structure not read in 2. I have failed to get a log/out file. Any help will be appreciated. Regards, S. Zarina __________________________________________________ Do You Yahoo!?

MPAIRS problem - 6.2 vs 6a
by Daniel John Rigden 20 Jun '02

20 Jun '02

Hi I'm having a problem with a simple modelling task in 6.2. I get the following error pick_re_612_> Number of MODEL atoms, selected restraints; 1440 13788 TOP_________> 393 234 OPTIMIZE pair2___223E> Array too small. Increase MPAIRS current maximum, current need: 4320 4320 recover____E> ERROR_STATUS >= STOP_ON_ERROR: 1 1 I see that this problem has been reported twice before but I didn't find any answer. What's new in this case is that I can run the same task file (on a different machine) with Modeller 6a with no problems. Any thoughts as to what's going on? Thanks in advance.

Error in win distribution
by Andras Fiser 20 Jun '02

20 Jun '02

-- dear windows version users of modeller, there was a wrong environment variable definition in the distribution package of modeller, effecting only the windows distribution. 2 ways to correct it: ###################################### please visit http://salilab.org/modeller/download_installation.shtml and download/reinstall the full mod6v2.zip windows version again, or alternatively, ###################################### you can download and replace only the faulty file in your distribution, called mod.bat, you will find it in /bin/mod.bat. To get this file: anonymous ftp salilab.org cd andras get mod.bat ###################################### Thanks for Jaroslaw Pillardy to pointing out this problem.

Ideal helices
by Dan Thomas Major 18 Jun '02

18 Jun '02

Hi, I'm modelling G-protein coupled receptors using rhodopsin as a template. When I compare the Ramachandran plot of the models vs that of rhodopsin, the models have much more ideal helices than the rhodopsin X-ray structure (2.8 A). Is this because: 1) The homology is relatively low (20-30%) and the distance constraints receive a low weight in the pdf function?? 2) The helices in rhodopsin are less regular than the globular proteins used in the pdf parametrization?? 3) None of the above...

user_distance, group restraints
by Karl Gruber 18 Jun '02

18 Jun '02

Dear Modeller team, I have got a couple of questions about the more uncommon restraint types that are available in Modeller (v62). There is a rather big loop in my target structure for which no homology derived restraints can be defined and which tends to protrude into the vacuum in the resulting models. I wanted to try 'user_distance' in order to get a more compact model but failed in producing a correct restraints file. test input file: ----- . . set atom_types = 'CA' pick_atoms pick_atoms_set=2, selection_segment='2:' '3:' pick_atoms pick_atoms_set=3, selection_segment='10:' '11:' set restraint_parameters = 3 1 1 27 2 2 0 0.0 0.010 make_restraints restraint_type='user_distance' . . ----- restraints file: ----- MODELLER5 VERSION: MODELLER FORMAT R 3 1 1 27 2 2 0 11 0 0.0000 0.0100 R 3 1 1 27 2 2 0 11 0 0.0000 0.0100 R 3 1 1 27 2 2 0 20 0 0.0000 0.0100 R 3 1 1 27 2 2 0 20 0 0.0000 0.0100 . . ----- It appears to be a problem of pick-set 3. The numbers of atoms and restraints are correct (also in more realistic examples) but the second set of atom indices gets lost somewhere along the way. My second bunch of questions concerns restraint feature 5 (distance between gravity centers). What is the exact format of this restraint? How are 'groups of atoms' defined in the rsr-file? Is it equivalent with defining the gravity centers as pseudo-atoms and restraining the distance between them? Thanks a lot in advance!

Mol file...
by Bkcho 13 Jun '02

13 Jun '02

Hi all modellers. I want to draw 3D small molecules (Mol file) for docking to my enzyme active site. Is there any freeware to draw 3D molecules and minimize it, such as SYBYL? Best wishes, Byung-Kwan Cho Ph.D candidate, Laboratory of Molecular Biotechnology and Biomaterials, School of Chemical Engineering, Seoul National University.
