Change it in the same file. Change the residue name and number, being careful to keep the rest of the columns in the same place. Also make sure that the new residue number isn't the same as some other residue. The fact that protein histidines are coordinating the metal shouldn't be an issue. Let me know if you run into problems. --Eric

error running Antechamber
by S Datta 22 Jun '07

22 Jun '07

Hi I am trying to prep a ligand using chimera for docking. When I try to add charges, one error which is always present is "Atom whose IDATM type has no Sybyl type: #-99.-99:1@CO(type: Co). At the end the reply log asks to check the total charge and spin multiplicity. When I manually change the total charge, after the Atom error briefly appears, Chimera either freezes (windows) or runs the program /../antechamber/exe/mopac.sh (in linux) infinitely. Could someone help me decipher what is going wrong ? I tried to change the input format of the ligand file from .pdb to .sy2 but that didnt help. thanks a lot SD ____________________________________________________________________________________ Got a little couch potato?

discontinuous ribbon for nuc. structure
by bala 20 Jun '07

20 Jun '07

Hello, While i make the ribbon representation for an RNA duplex, sometimes ribbon is discontinuous in between, what could be the reason for it ? I hve two conformation sof the same duplex taken at 1ns interval from MD trajectory. For one conformation, ribbon is continuous but for the other there is a discontinuity at the middle.. I analysed the structure, it seems ok. thanks in advance, Bala

Delphi calculation for electrostatic surface potential
by Shunsuke Meshitsuka 18 Jun '07

18 Jun '07

Dear Doctors, I want to calculate surface potential by Delphi type calculation. I have tried from Menu bar, tool --- DelPhi ,but have not obtained the results. Please let me know the way to use them for the calculation of surface potentials from a PDB fie in linux version of chimera-1.2417. Shunsuke Meshitsuka D.Sci., D.Med.

to view nmr pdb structures
by Shunsuke Meshitsuka 15 Jun '07

15 Jun '07

Dear researchers, I have used chimera as a viewer of proteins. I have a question how to overlay the 20 structures of NMR pdb data by chimera. When there are 20 structures of structurename01.pdb, structurename02.pdb,,,structurename20.pdb, > chimera structurename**.pdb makes a random location and random orientation of each protein. Please let me know the method. Shunsuke Meshitsuka D.Sci., D.Med.

release next week
by Elaine Meng 14 Jun '07

14 Jun '07

Dear Chimera users, As you may know, we made a production release earlier this month. Since then, a few bugs have come to our attention that were not revealed by our test suite or by users during the "release candidate" phase. We plan to make another production release late next week with the following fixes: - ensure POV-Ray image view always matches that in Chimera, instead of most of the time 8-) - make Minimize Structure work with metal ions (those in Amber parm94: calcium, magnesium, iron, etc.) - fix saving of sessions when sequences have been added to an alignment in Multalign Viewer (current workaround is to save the modified alignment to an alignment file) There may be additional updates and minor fixes not mentioned here. Best, Elaine ----- Elaine C.

hi Elaine, I just loaded a pdb, selected an off-center atom, typed 'cofr' at commandline, and the cofr does not appear to change (rotation looks the same in the chimera window).

Re: [Chimera-users] export scene to maya, obj, iges, stl, dwg-dxp?
by Greg Couch 14 Jun '07

14 Jun '07

Just to follow up, the Maya VRML2 importer is actually a conversion program in Maya's bin directory. On Windows the program is called wrl2ma.exe and on Linux and Mac OS X it is called wrl2ma. See the Maya documentation for details. - Greg
