Tkinter_Idle askyesno issue
by Wolf Cochrane 11 Jan '06

11 Jan '06

Hi Is it just me of does this bit of code always print "False" when run through Idle (Chimera v1.2065). If so, how to I get around it without having to build my own dialogs. import Tkinter import tkMessageBox #root = Tk() #root.geometry("500x510") #root.title("Yes/No") #root.mainloop() print tkMessageBox.askyesno("Linker range","Click Yes if a range of Linkers will be used at this Permutation Site") Thanks Wolf

Concerns regarding secondary structure
by rquiroga＠immf.uncor.edu 08 Dec '05

Greetings, I have some concerns with Chimera's secondary structure detection/depiction. I am using Modeller to predict some 3D structures. I open my predicted structure in pdb file in Chimera along with the original structure I based my prediction on, and find that my predicted structure lacks two beta sheets that the model protein has, though the AA that compose the B-sheet are identical for the two proteins when I compare sequences with Matchmaker. I tried opening my predicted structure in MolMol and it detects the B-sheet, though I hugely prefer Chimera, so if you could solve this problem for me I would be very greatful. Thanks in advance, and regards Rodrigo Quiroga

collaboratory tool
by Xavier Deupi 22 Nov '05

22 Nov '05

Hi, In the workshop last week I asked some of you about the collaboratory tool. Well, I'm making some tests and, so far, it has more or less worked between two computers in our lab. Now I want to try 'outside' the university firewall. But during the tests, Chimera has crashed a couple of times when I was joining the session I had just started. I include the error report generated by my computer (a PowerBook G4). I don't think I made anything different the times it has worked than the times the program crashed. Hope the error report makes some sense to you. Thanks, xavi *********************************************** Date/Time: 2005-11-21 13:59:03.443 -0800 OS Version: 10.4.3 (Build 8F46) Report Version: 3 Command: python2.4 Path:

Reference Manual

17 Nov '05

Dear Chimera Staff, I was wondering where can I get an offline reference manual (*.pdf) for Chimera if there is any? I noticed that the documentation site only has user guides available for online viewing. Or will you be putting together something like that soon? Thank you and good day Reiner Villavicencio BS Biochemistry Dept. of Physical Sciences and Mathematics College of Arts and Sciences University of the Philippines, Manila "Its hard to hold on to something that can never be yours in anyway you want... something that wasnt really yours to begin with... you just have to go on and accept the fact that while good things never last some dont even start...."

Re: [chimera-dev] [Chimera-users] Rotation callback
by Eric Pettersen 11 Nov '05

11 Nov '05

Hi Charlie, The answer is: sort of. You can't get a callback for when a specific model moves, but you can get callbacks for when any models move and from there it's pretty easy to deduce if models you are interested in moved. There are two possible triggers you could use. The one most typically used is chimera.MOTION_STOP (mentioned in the Trigger Notifications programming example), which fires one second after models have stopped moving (the motion can be due to user interaction or programmatic repositioning). On the assumption that what you want to do in response to the trigger is somewhat heavyweight, this is the trigger you would want to use. The other trigger is 'OpenState', which will fire many times as a motion occurs. If you use this trigger, you could check to see if the trigger data's 'modified' attribute contains the OpenState instance of the model(s) you care about and whether the trigger data's 'reasons' attribute contains the string "transformation change". There is an OpenState instance for each model ID/subID pair. So some models share a single OpenState instance (e.g. a structure model and corresponding surface model). Models have an 'openState' attribute, and OpenState instances have an 'xform' attribute containing the transformation matrix. If you use the MOTION_STOP trigger, you would compare the transforms of the models you care about with previous ones that you'd saved to determine if the models had moved. UndoMove is an example of an extension that uses MOTION_STOP. --Eric Eric Pettersen UCSF Computer Graphics Lab pett(a)cgl.ucsf.edu http://www.cgl.ucsf.edu On Nov 10, 2005, at 12:06 PM, Charlie Moad wrote: > Is it possible to register a python callback for when a protein is > rotated and get the rotation information? > > Thanks, > Charlie > > _______________________________________________ > Chimera-users mailing list > Chimera-users(a)cgl.ucsf.edu > http://www.cgl.ucsf.edu/mailman/listinfo/chimera-users

(Replies should be sent to chimera-dev(a)cgl.ucsf.edu) Sending commands and data to chimera can be done with the --send command line argument that was added for web browser support (it's not enabled by default except on Mac OS X, use Tools/Preferences Web Access to "Accept web data"). For bidirectional communication, you'll need to add some Python code -- python supports the same IPC that the underlying C library does, but the IPC should be integrated into the chimera event loop -- look at the socket code from CHIMERA/share/DBPuppet/tcl_sockets.py to see an example of integrating Internet sockets. Internet sockets are the general solution because standard input and output can only be used by one other appliction, but there are security issues. Chimera uses a shared key (read from the filesystem) security protocol to prevent hijacking of the web browser connection. I'd also recommend creating a chimera extension with all of the STRAP related code in it. For examples on how to do that, see the Chimera Programmer's Guide examples, <http://www.cgl.ucsf.edu/chimera/docs/ProgrammersGuide/Examples/index.html>. The examples also show how to use chimera selections pragrammatically. So the answer is yes, chimera could be linked to STRAP. I hope this answer gives you some ideas on how to proceed. I would be delighted to work with you to get the programs working together. Greg Couch UCSF Computer Graphics Lab gregc(a)cgl.ucsf.edu

Recent API changes
by Greg Couch 18 Oct '05

18 Oct '05

Hello Developers, In the recent chimera release candidates and the imminent 1.2180 production release, there several API changes that may trip up existing code. Many of these changes are due to our improved method of moving data between Python and the underlying C++ layer (roughly 2X faster). Most of the changes are detailed below. Greg Couch gregc(a)cgl.ucsf.edu ------ The new code works much better with the Python help function. In the IDLE window, try help(chimera.Atom) and you'll see all of Atom's methods and their argument types and return values. For the changes below assume: m is a Molecule r is a Residue a is an Atom b is a Bond x is a Xform Atoms have a simpified interface to their bonds: a.bonds() returns a list of bonds a.neighbors() returns a list of adjacent atoms (via bonds) a.bondsMap() is both of the above combined as a dictionary and is what a.bonds() used to return If a structure has alternate locations, you can get just the highest occupancy bonds/atoms with a.primaryBonds() and a.primaryNeighbors(). Molecules have a corresponding m.primaryAtoms() function. Residues have a simpified interface to their atoms: r.atoms() returns a list of atoms r.atomNames() returns a list of atom names r.atomsMap() is both of the above combined as a dictionary with atom name as the key and a list of atoms with that name as the value Residue ids (of type MolResId) no longer have an exposed str method: r.id.str() is now 'str(r.id)' or 'print r.id' MolResId, Point, Vector, and Xform now have copy constructors. You can make copies in the C++ style, 'xprime = Xform(x)', or in the Python style with the copy module or the __copy__ method. The following chimera module functions are now static methods: Atom_getIdatmInfoMap -> Atom.getIdatmInfoMap Camera_hasMode -> Camera.hasMode Camera_modes -> Camera.modes Color_list -> Color.list Color_lookup -> Color.lookup Color_remove** Element_bondLength -> Element.bondLength Element_bondRadius -> Element.bondRadius LODControl_get -> LODControl.get Material_list -> Material.list Material_lookup -> Material.lookup Material_remove** Mol2io_isBlankLine -> Mol2io.isBlankLine Mol2io_splitLine -> Mol2io.splitLine OGLFont_defaultFont -> OGLFont.defaultFont OGLFont_setDefaultFont -> OGLFont.setDefaultFont OpenModels_get -> OpenModels.get PDBio_addStandardResidue -> PDBio.addStandardResidue PDBio_bondLengthTolerance -> PDBio.bondLengthTolerance PDBio_removeStandardResidue -> PDBio.removeStandardResidue PDBio_setBondLengthTolerance -> PDBio.setBondLengthTolerance PDBio_standardResidue -> PDBio.standardResidue PixelMap_list -> PixelMap.list PixelMap_lookup -> PixelMap.lookup PixelMap_maxLength -> PixelMap.maxLength PixelMap_remove** PseudoBondMgr_mgr -> PseudoBondMgr.mgr Residue_getDefaultRibbonStyle -> Residue.getDefaultRibbonStyle RibbonResidueClass_classes -> RibbonResidueClass.classes RibbonResidueClass_deregisterClass -> RibbonResidueClass.deregisterClass RibbonResidueClass_registerClass -> RibbonResidueClass.registerClass RibbonXSection_circle -> RibbonXSection.circle RibbonXSection_line -> RibbonXSection.line RibbonXSection_square -> RibbonXSection.square Selectable_count -> Selectable.count Shader_list -> Shader.list Shader_lookup -> Shader.lookup Shader_remove** Spline_makeGeometryVector -> Spline.makeGeometryVector Texture_computeComponents -> Texture.computeComponents Texture_computeDimension -> Texture.computeDimension Texture_computeImageTypeBytes -> Texture.computeImageTypeBytes Texture_computeTarget -> Texture.computeTarget Texture_list -> Texture.list Texture_lookup -> Texture.lookup Texture_remove** TrackChanges_get -> TrackChanges.get Xform_coordFrame -> Xform.coordFrame Xform_identity -> Xform.identity Xform_lookAt -> Xform.lookAt Xform_rotation -> Xform.rotation Xform_translation -> Xform.translation Xform_xRotation -> Xform.xRotation Xform_xform -> Xform.xform Xform_yRotation -> Xform.yRotation Xform_zAlign -> Xform.zAlign Xform_zRotation -> Xform.zRotation ** Color_remove, Material_remove, PixelMap_remove, Shader_remove, and Texture_remove Unlike C++, Python can not have a method and a static method with the same name. So the static method versions have been excised from the Python layer.

Getting the selected elements
by Wolf Cochrane 06 Oct '05

Hi, I've written software and want to use Chimera as vector application for it. As a input step I want the user to select a atom on a structure, using his/her mouse in the Chimera GUI. I've had a look at the Chimera code and online documentation but haven't been able to figure out how to get the selected elements (Existing elements) on a structure. I will appreciate it if you can help me out. Regards Wolf Cochrane Bioinformatics and computational Biology Unit University Pretoria
