Chimera Multiscale using VRML?
by Thomas Goddard 10 Dec '04

10 Dec '04

Hi Dong, The Chimera Multiscale extension is described in the Chimera User's Guide in the Tools section. http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/multiscale/framemu… It currently calculates surfaces for PDB models and positions multiple copies of those surfaces using matrices, like the BIOMT (biological unit) matrices in PDB file headers. If I understand your question correctly, you want multiscale to use your own VRML model for individual proteins instead of the surfaces it normally calculates. It won't do that, and it is not a simple change to make. If you want a VRML model of a virus and you have the positioning matrices and a VRML surface for one asymmetric unit, you could create a new VRML file in an editor using the Transform VRML node to position each of the subunits. But such a model would not be interactive like the Multiscale models -- you would not be able to change to ribbon display, look at atomic contacts, ....

As you already noticed, if you just use "addh" the aspartic and glutamic acid carboxylate groups will not get protonated. In the definitions of these residues, the carboxylate oxygen atoms are type O2-, which would not get protonated. You can use Define Attribute to change the types of these atoms. First you need to know the residue number of the aspartic acid you want to protonate and which of the oxygens (OD1 or OD2) you want to receive the proton. Next, create a define attribute input file in which you specify these two atoms and change type of the oxygen you want protonated to O3 and the one you don't want protonated to type O2 (example attached). There is a file description and more examples in the manual page for Define Attribute, http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/defineattrib/ defineattrib.html In Chimera: open your PDB file of interest run addh (note the aspartic acid is not protonated in this step) Tools... Utilities... Define Attribute (open the previously prepared input file) now run addh again (note the aspartic acid will be protonated) The proton may not be pointing the direction you want, so you will probably then want to rotate the OH to the proper position, as described in http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/structuremeas/ structuremeas.html#adjust My define attribute example file (attached) works with the PDB file 1zik. The define attribute file tells Chimera to change the atom types of Asp residue number 7 in chain B so that the side chain will be neutralized when AddH is run.

release candidate
by Eric Pettersen 06 Dec '04

06 Dec '04

Hi, We've put out a "release candidate" for download (version 1.2056). We're hoping people will download it and try it and report any problems they find before we make a production release version in early January. The production release candidate will be functionally identical to the production release, except that we will fix any bugs reported between then and now. There are some new features in the 1.2056 release, and if you are interested in those you should really try it out so that if you find any problems they will be fixed in the production release. Here's a synopsis of the major new features since the 1.2038 release: NEW TOOLS: Surface Area/Volume (Utilities) - calculate surface areas and Voronoi volumes with the StrucTools server at http://molbio.info.nih.gov/structbio/basic.html TOOL CHANGES: Movie - support added for MMTK/NetCDF trajectory format - RMSD maps containing all-by-all comparisons among specified frames can be calculated (for all atoms or selected atoms) Volume Viewer - support added for APBS electrostatic potential format and TOM toolbox EM density map format sequence panel (opened from Model Panel) - secondary structure shown with color NEW COMMANDS: matrixget - write the current transformation matrices to a file matrixset - read and apply the transformation matrices from a file mmaker (matchmaker) - command implementation of MatchMaker; generates a sequence alignment for two structures and then superimposes the structures accordingly BUGS FIXED: large structures without HELIX/SHEET records now much faster to open (fixed bug in secondary-structure computation) non-default ribbon scalings from pre-1.2038 versions no longer cause bombing on startup (1.2038 would die at startup for such) Eric Pettersen UCSF Computer Graphics Lab pett(a)cgl.ucsf.edu

Labeling Residues
by Stephen P. Molnar, Ph.D. 01 Dec '04

01 Dec '04

I have to admit to being completly flumoxed [sic] by this one! How do I label an individual residue: According to help the format is: wt %(1-letter code)s%(number)s Now I have an enzyme, 1QTI.pdb in which I wish to label the SER200 label. I have tried every combination of the example on the help page that I can think of without success. What is the exact format for creating that label? Thanks in advance. -- Stephen P.

netCDF trajectories?
by John R. Frank 24 Nov '04

24 Nov '04

Tom and other users, Based on this posting, I deduce that Chimera's Movie capability cannot yet display netCDF trajectories: http://www.cgl.ucsf.edu/pipermail/chimera-users/2004-June/000171.html MMTK generates netCDF trajectories. Can you recommend any already-built tools for converting them to multi-model PDBs? Or, perhaps you can direct me to the parts of Chimera where I could help add netCDF trajectory support?

Re: [Chimera-users] Select Function
by Elaine Meng 23 Nov '04

23 Nov '04

Dear Dr. Molnar, All chains present in structures open in Chimera should be listed. If two chains have the same ID, however, they will not have separate listings in Select/Chain. Another thing that might be confusing is that residues can be assigned to chains named "het" or "water": Any HETATM residue that does not already have a chain identifier is assigned to chain HET, unless the residue is named WAT or HOH, in which case it is assigned to chain WATER. Additional possibilities are a bug or something strange with the input files. If you have some input files that demonstrate the problem (and don't mind sharing them), you could send them to me or to chimera-bugs(a)cgl.ucsf.edu along with a short explanation of how to duplicate the problem (how files were opened, what order).

I want to load two files, one for the protein and the other for the ligand. This is, of course, not a problem. The question is how do I get both files to be present as choices in Select/Chain?

Chimera / APBS
by Thomas Goddard 23 Nov '04

23 Nov '04

Hi Miguel, Eric Pettersen passed to me your question about Chimera reading APBS electrostatic potential maps. It looks easy to add -- probably only take me a couple hours if it is the OpenDX file format described in the APBS documentation. Could you provide me an small example file? I'll be on vacation this week starting this afternoon but I can probably do it early next week and send you the Python code for use in your current version of Chimera. Tom

We have now made a production release, version 1.2038, that corrects a few problems in the 1.2029 snapshot and adds a tiny number of new features. The salient new features that weren't in the 1.2029 snapshot are: Actions...Label now allows much more flexible labeling of residues Per-Model Clipping now allows a model's clip plane to be aligned with the clip plane of another model, and allows a clip plane to be flipped 180 degrees.

Re: [Chimera-users] Specifying residue color of residues with a text file
by Elaine Meng 20 Oct '04

20 Oct '04

Hi David, You can specify residues and corresponding R,G,B values using Define Attribute, which is included in our newer releases (snapshot 1.2029 and production release 1.2038, of which I recommend the latter). Basically, this tool reads a file that specifies the residues and the associated values. The manual page for Define Attribute can be viewed at: http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/defineattrib/defin… including three examples near the end: http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/defineattrib/defin… There are two general approaches you may want to consider: (1) the direct approach that you described. Just reassign R,G,B values to the existing attribute of atom color and/or residue ribbonColor. This is most like the third example, except that you would use residue specifications by number (e.g., :12.A) instead of name, and the color specifications would be in the form of R G B (e.g., 1.0 0.2 1.0) instead of color names. (2) a less direct approach but one that provides more flexibility in how you show the data. Create your own new attribute (as in the first example). Then, you can use Render by Attribute (http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/render/render.html) to show these values with colors, atom radii, and/or "worm" radii. The data will show as a histogram, and the mapping to colors and radii can be controlled with markers you place on the histogram. This may be a lot to digest, so please feel free to contact us with any further questions/issues. Thanks, Elaine ------------------- Elaine C.

[Chimera-users] Specifying residue color of residues with a text file
by David Piper 20 Oct '04

20 Oct '04

Chimera, Is it possible to provide a color input file that would include a residue number and an [R,G,B] value to color each residue in a structure? Or does one simply have to select each residue seperately within the program and specify an [R,G,B] value? For example, I would like to map some experimentally measured, functional data onto a model structure by coding it into a color. Would be much easier to use a lookup table of values than click and set each one. Thanks, David

new Chimera snapshot release
by Eric Pettersen 19 Oct '04

19 Oct '04

Hi all, A new Chimera snapshot release (version 1.2029) is now available for download. I've summarized the major changes since the last release (1.1951) below. A list of _all_ the changes since the last release is in the release notes: http://www.cgl.ucsf.edu/chimera/docs/relnotes/1.2029.html Eric Pettersen UCSF Computer Graphics Lab pett at cgl.ucsf.edu http://www.cgl.ucsf.edu General changes --------------- The "web fetch" part of the "File...Open" dialog has been split off into its own "Fetch by ID" dialog. The Fetch dialog now supports fetching NDB IDs. Labels are now offset in the viewing coordinate system (rather than the model coordinate system), making them much less likely to be obscured. Moved C3' off of ribbon backbone so that the sugar ring isn't distorted. New Tools --------- Nucleotides (Graphics): create various nucleotide-specific depictions, such as stylized representations of base pairings or filled sugar rings Define Attribute (Utilities, Programming): assign values to new or existing attributes of atoms, residues, or models. Particularly useful in conjunction with the Render by Attribute tool. Tool Changes ------------ AddH improved to avoid steric clashes (and appears in model panel) Match -> Align can handle circular permutations in multiple alignments [formerly only in pairwise] Movie can read PSF/DCD files from CHARMM, NAMD, and X-PLOR; can read PDB-format trajectories (single concatenated file or one file per frame) Multalign Viewer can save a subset of an alignment to a file Multiscale Models includes the zone-selection options Near and Contacts PipesAndPlanks now connects the secondary structure elements with loops Web Data preference category renamed to Web Access and includes HTTP proxy options Render by Attribute implements Radii section (atom radius scales with attribute value) and Worms section ("worm" ribbon radius scales with attribute value) Ribbon Style Editor scalings are now treated similarly to cross sections (per-residue, no startup default except in New Molecules preferences); new "residue class" tab allows specification of which atoms should guide the ribbon, this generalizing ribbons to polymers other than standard peptides and nucleic acids ViewDock includes new interface for choosing compounds by descriptor values New Commands ------------ addaa: add amino acids to the C-terminus of a peptide/protein addh: add hydrogens (command implementation of AddH) bond/~bond: create and delete bonds chirality: report the R/S configuration of a chiral center (see User's Guide for caveats) defattr: define a new attribute and/or assign attribute values (command implementation of Define Attribute) rangecolor: color over a range according to attribute values rmsd: evaluate the RMSD between specified sets of atoms (without matching) Command Changes --------------- atom specification operators added for union (|) and negation (~) [previously just intersection (&) and operators for combining attributes] hbonds has "tilde version" (~hbonds) which removes the pseudobonds showing hydrogen bonds labelopt info has "res" or "residue" keyword indicating that only residue name and number should be shown (not atom name) rainbow can color by model (previously only by residue or chain); likewise for Rainbow tool select has "up" or "down" arguments which behave like up-arrow and down-arrow to broaden and narrow a pre-existing selection

Dear Srs: I am a new user of Chimera, and I really like it! I would like to know if some of the developers could include a new format for density maps amongs those that are readable in Chimera: EM format. That would increase its use in our group, because now we need convert our density maps to mrc each time that we want to use Chimera. With my actual skills in programming, to write a plugin will take me like a year, and I think that should be relative easy for someone with experience. As attachment I am sending a text file with a procedure wrote in matlab to read EM format files. The syntax should not be so different from python. I could also provide you with test data.

[Chimera-users] Re: streaks in Chimera image of virus electron density map
by Thomas Goddard 12 Oct '04

12 Oct '04

Hi Lu, The streaks on your Chimera density map display are very likely a driver bug specific to the Mac ATI Radeon 9600 Pro (RV350, 64 Mb). You don't see the streaks on a Mac with Radeon 9600 XT graphics (RV360, 128 Mb), and I don't see them with your data set on my Mac Radeon 9800 Pro (R350, 128 Mb). Setting the transparency to a non-zero value makes the streaks go away. When you use transparency Chimera does not use OpenGL display lists. This suggests that the graphics driver bug is related to display lists. OpenGL is an industry standard 3D graphics library that Chimera uses. We have had alot of graphics driver problems with Apple. We submit bug reports to them and sometimes visit them in Cupertino, but it is unlikely we could get this fixed since it appears to be limited to a graphics card they no longer sell. If the streaks do not bother you on-screen too much, a reasonable work-around might be to set transparency to 0.001 just when saving an image. This setting will substantially slow down rotation of the model so it is best to leave the transparency at 0 until you get the right orientation for image saving. Thanks for reporting the problem.

Can I ask you in what context you are doing this? Is it related to an MD trajectory? Perhaps in future releases we could make this easier if we know specifically what you want to do and what data you are working from. Anyway, there are two methods I can suggest: VRML and pseudobonds. You can show exactly what you want with VRML, but it may be more effort. Pseudobonds may be easier, but you can’t have arrowheads. For VRML, you just compose a VRML file using a cylinder and cone for each arrow. The cone is the “arrowhead” and you have the cylinder go from the atom to the base of the cone, and have the cone point in the right direction. If you don’t know how to use VRML, this page has a spec and examples: http://www.web3d.org/x3d/specifications/vrml/ISO_IEC_14772-All/ index.html For pseudobonds, you would make up a fake molecule where the “atoms” are at the ends of the vectors you want to show. If you make a PDB file, start it with a TER card and use HETATM records for each atom, with a different residue number for each. This will ensure that Chimera won’t connect any of the atoms in the fake molecule. You can then use the PBReader tool (in the Utilities category) to read in the pseudobonds to display (including colors and optional labels). You can use the pseudobond panel (under inspectors) to control if the pseudobonds are wires or sticks, if they are dashed [wire only], and so forth. Let me know if you need any more help getting started with this. Eric Pettersen UCSF Computer Graphics Lab pett(a)cgl.ucsf.edu http://www.cgl.ucsf.edu

[Chimera-users] streaks in Chimera image of virus electron density map
by Lu 11 Oct '04

11 Oct '04

Hello, I've been using Chimera to generate beautiful images of entire virus particle from an O-style map file. However, most of the images that I capture have a few black streaks in the image. The streaks appear as thin, parallel lines, like someone dragged a pen across a painting before it dried. Does anyone know how I can remove these streaks without having to resort to Photoshop? I can provide sample images too. Thanks in advance! -Lu Gan

Problems in Windows XP

To whom it may concern: We have been trying to run chimera in Windows XP and unfortunately are not able to do so. The program runs great on the Mac machines though. The only problem obvious for us is, that the collaboratoryHub shortcut does not show up. We can start the program, but when we try to open a file the sequence window starts flickering and the structure does not load. We really like the program a lot and would like to cite it in a paper we are currently working on, but in order to do that we need to get it to work on the PCs. Therefore every advice would be highly appreciated. Thanks!
