Chimera Shutting Down
by Joshua Broyde 26 Mar '14

26 Mar '14

Hi, I am using the Chimera Linux 64-bit (chimera-alpha-linux_x86_64.bin), and Chimera shuts down when I try to open the Side View option. I tried the workaround mentioned here: http://plato.cgl.ucsf.edu/pipermail/chimera-users/2013-April/008765.html but it is not working for me. OS: Ubuntu 12.04 Version of Chimera: Linux 64-bit Daily Build (Mar 24, 2014) For what it's worth, on another computer where I am running Ubuntu 12.10, with Chimera Linux 64-bit Daily Build (July 10, 2013), I did not have this problem. Is there another workaround that I could do to open the side view? Thanks! Sincerely, Joshua Broyde

Viewing Gromacs 4.6.5 trajectories
by William McDonald 26 Mar '14

26 Mar '14

Hello Chimera users, I recently upgraded my gromacs simulation software from 4.5.5 to 4.6.5; however, when I attempt to load a new simulation trajectory (either a .xtc or .trr file), Chimera allocates ~13GB RAM causing my machine to swap, and Chimera never loads the trajectory. The old trajectories from gromacs 4.5.5 load with out any problems. Has anyone else experienced this? I am using 64 bit Chimera 1.8.1 on a dual quad-core Mac Pro running OS 10.6.8. The simulation has ~50000 atoms of protein, lipid, and water and is 1ns long. -- William J.

Hi everybody, I’ve conducted Principal Component Analysis on a trajectory and generated an ensemble of structures (see attachment, pc2.pdb). There should be a way of coloring (occupancy?) the most mobile regions of the protein (e.g. residues 67 - 72). I haven’t found a way to do this. Any help would be much appreciated.

stereo3D

I have a toshiba qosmio x875-7390 S3D laptop, which is based on the NVidia NVision 3D. Toshiba structured the device to be user unfriendly, limiting stereo3D for bluray and youtube 3d via adobe flash. coming across a pymol S3D post I see there is a workaround, for a different Toshiba model. http://nanonan.wordpress.com/2012/03/28/pymol-and-coot-3d-stereo-on-qosmio-… http://coxcoppes.nl/3DScreenActivator/index.php?pagina=1 Any comments about chimera using S3D on NVidia NVision 3D?

Detection of Internal water along MD trajectory
by James Starlight 20 Mar '14

20 Mar '14

Dear Chimera users! I've performed md simulation of water soluble protein having water-assessable channel in its interior. I'd like to perform analysis of average number of water molecules detected within the protein interior during MD trajectory with the possible visualization of such internal water binding sites. Does SASA calculation which I've seen in vmd could provide me with additional insights? I'd be thankful if you provide me with some Chimera tools suitable for such task. Many thanks for help, James

Morph conformation - conformation collapsing
by Helge.Paternoga＠bzh.uni-heidelberg.de 18 Mar '14

18 Mar '14

Hello, I'm trying to morph two structures which have two chains each. The problem is that if I just add the two confirmations one chain will turn the wrong way, because it is taking the shortest distance to the final position. What i did now is I used this initial morphing to extract 4 frames of the movement of the other chain and inserted the movement of the smaller chain in each of these structures by hand (so the movement is in the right direction and happening at the same time as the other chain). But when I now add these 4 structures in my morph confirmation list like this: Start confirmation frame 1 frame 2 frame 3 frame 4 End confirmation It nicely starts moving in the right way but then at a transition to a new frame the whole structre collapses, bonds get distorted, it somehow shrinks and then extends again later to end up at the final confirmation... I think this is independent of which frame i use (I tried to simplify it by using only 2 intermediates) Do you have any idea what is causing this collapse? The initial confirmation has the same number of chains as the end confirmation (with the same names) but they have a different number of atoms (which i don't quite understand because they are the same macromolecules...) Could this be part of the problem? best regards, Helge

residue number in Gromacs tpr file
by Mario Dejung 17 Mar '14

17 Mar '14

Hi all, I am experimenting with Gromacs a little bit and try to open the tpr file and the corresponding trajectory in chimera. Works fine, but the numbering is completely wrong. The residues get numbered continuous and not starting at 1 for the next chain. Not sure if the problem is in the tpr file or in chimera. I have 4 chains in my pdb file and all have a chain identifier, O P g and h and they are separated by TER I have also 4 .itp files with names like “topol_Protein_chain_O.itp” My topol.top file say 4 molecules [ molecules ] ; Compound #mols Protein_chain_O 1 Protein_chain_P 1 Protein_chain_g 1 Protein_chain_h 1 and ; Include chain topologies #include "topol_Protein_chain_O.itp" #include "topol_Protein_chain_P.itp" #include "topol_Protein_chain_g.itp" #include “topol_Protein_chain_h.itp" I create my tpr file with grompp Has anybody experience with this kind of issue? Kind regards Mario

Chimera and XP?
by Boaz Shaanan 13 Mar '14

13 Mar '14

Hi, For some reason, I couldn't get Chimera (1.8.1 and the 12/3 daily build) to work today on my laptop running XP (32bit). It gets stuck in 'initializing graphics'. See attached screen shot of run with --debug. Chimera worked for years on this machine. Other programs work fine (spdbv, Coot, etc.). I can't imagine it has to do with the imminent downfall of XP support, or maybe it does? Please advise.

'Old-style' silhouette edges?
by Thomas Mitterfellner 13 Mar '14

13 Mar '14

Hello! It seems that somewhere between 1.6.2 and 1.7, the way silhouette edges are drawn has changed. Most of the silhouette edges are now drawn in white regardless of the color I set (presumably due to some smart algorithm?). In my opinion, the old way gave a much clearer appearance of the molecule on different backgrounds and it gave it a 'cartoonish' flavor which made it look quite distinguished from the images other software produces and I really loved that. So my question is: is there any way to get back the 'old-style' (pre 1.7) silhouette edges in 1.7+ releases? Kind regards, Thomas

Hello: I would appreciate receiving instructions on changing selected dihedral angles in a peptide. Imagine that the initial and final stretches are alpha-helices, while in the middle, dihedral angles are such that two alpha-helix coiled portions make an angle different from 180 degrees. In all that, all dihedrals in the alpha-helix portions should not be modified. Thanks francesco pietra

Visualizing trajectory
by Yasser Almeida Hernández 10 Mar '14

10 Mar '14

Hi all, I have a MD trajectory from GROMACS and I want to visualize it in Chimera using MD Movie tool. My protein move inside the water box. How I cant fix the protein to see the its dynamics in each frame? I have used VMD for this task, using the RMSD trajectory calculator plugin. Here the trajectory is loaded and then press the Align button. The protein coordinates in each frame is superposed on those from the first frame. Whith this the protein stay in a fixed position. It is this possible in Chimera? On the other hand, It is possible load the trajectory just by every N frames? I have a trajectory with 2 000 000 of frames, and I want to load the trajectory every 100 frames. Thanks in advance Yasser -- Yasser Almeida Hernández, MSc.

CHIMERA: help with stereo viz on new samsung "3D" LCD and quadro card
by Peter Engelhardt 07 Mar '14

Sorry2 for a typo - now corrected: Dear Chimera, We recently got a mail on instruction to install correct parameters to get VMD-L to work: "vmd-l: help with stereo viz on new samsung "3D" LCD and quadro card" Now we ask, do you have any suggestions to get "Samsung "3D" LCD and quadro card" to work - not only for: 1. Linux (Ubuntu) with "quadro card" but also and on: 2. MacPro/Mavericks with "a quadro card" We thank you in advance Cheers Peter et al. Quoting John Stone <johns(a)ks.uiuc.edu>: [Hide Quoted Text] Carlos, Ah, I had missed the startup message you included when I read your first note. All of the VMD stereo modes other than "QuadBuffered" are implemented by rendering code within VMD itself, and they do not depend on the graphics driver or any special hardware capabilities. So, the fact that you are able to use the "SideBySide" or other modes just indicates that your TV can work with the VMD-supplied mode, but that's separate from the issue of having the Quadro's stereo sync and other features working. The VMD "QuadBuffered" stereo mode relies entirely on the GPU and its driver for stereoscopic display. This is the best mode to use if you want the IR or RF stereo emitter to remain in proper sync with the displayed images, but it requires that the GPU drivers and windowing system be configured correctly, and that the GPU and driver will actually support the target display. If you're running on Linux, then the thing to do is to check the contents of /var/log/Xorg.0.log and look for the word "Stereo". Here's an example of the kinds of output you're looking for, as seen on a couple of our machines: (**) NVIDIA(1): Option "Stereo" "10" (**) NVIDIA(1): Option "ForceStereoFlipping" "true" Here's a machine that has stereo enabled: (II) Setting vga for screen 0.

I included VMD's output in my original post- yes, it says stereo, and I can indeed get VMD to do stereo if I pick side by side mode in VMD. I'm using win 7 pro (though I'd upgrade to win 8 if I knew that would solve the problem). The TV is HDMI only, unfortunately. The quadro card has only DVI outputs, so I'm using a DVI to HDMI cable. I'm hoping to find a way to do quad buffered stereo at a reasonable refresh rate. Carlos On Mon, Feb 17, 2014 at 12:53 PM, John Stone <johns(a)ks.uiuc.edu> wrote: Hi Carlos, I'm not familiar with the TV you're using, but I can say a few things that are broadly true of a wide range of HDTVs that support stereo that may also apply in your case. If a TV has a DVI input (unlikely), then one is sometimes able to use it just like any other stereo display. If the TV uses HDMI, then the options for stereo will depend somewhat on which operating system the computer is running what video card, and what driver are being used. In regards to the NVIDIA GPUs, the "Quadro" GPUs have the best support for stereoscopic display across all OS platforms. Last I knew however, HDTVs are considered a special case, and at least on the Windows platform there was/is a special driver that one had to use to allow stereoscopic display to an HDTV over HDMI (3DTV Play) for games and the like: http://www.nvidia.com/object/3dtv-play-overview.html I just looked up the NVIDIA web site regarding stereoscopic display, and they have clearly rewritten much of it since the last time I looked: http://www.nvidia.com/object/3d-vision-professional-users.html I would expect that the Quadro would have a good chance of working with a 3D HDTV, but you will likely have to set the NVIDIA driver's stereo mode to one that your TV agrees with. If you tell me which OS you're running, we can work through a few of the details there. The most important thing is to see if VMD lists "STEREO" during the OpenGL feature startup messages that it prints to the text console.

I have windows 7 pro, a quadro fx-4600 and a samsung UN60F8000BF LCD TV (http://www.samsung.com/us/video/tvs/UN60F8000BFXZA) that came with active stereo glasses. I also have an old stereographics emitter with 3-pin DIN connector that plugs into my quadro card, along with some stereographics glasses. VMD tells me this at startup: Info) OpenGL renderer: Quadro FX 4600/PCIe/SSE2 Info) Features: STENCIL STEREO MDE CVA MTX NPOT PP PS GLSL(OVF) So, what I need help with is optimizing my 3D viewing. So far I can only get this setup to work when I select side by side 3D in VMD, and on the TV I also select side by side and use the glasses that came with it. It's ok, but the glasses are cheap and there's some bleed through, and of course I lose resolution. I suspect I'd be better off using the emitter and the expensive SG glasses. When I plug in the emitter, the red light goes on so it seems to be working. If I select stereo/quadbuffered in VMD, it looks like it's doing the right thing, but using the SG glasses doesn't seem to sync properly. A few other questions: 1) do the settings in the Nvidia control panel under "manage 3D settings" impact VMD? In there you can choose the 3D mode, antialiasing, etc. I don't know if that controls the openGL part. 2) Is it possible to send a >60HZ signal to these screens? It claims it is 240Hz, but I don't know if that's internal interpolation or accepts inputs >60Hz. thanks! -- NIH Center for Macromolecular Modeling and Bioinformatics Beckman Institute for Advanced Science and Technology University of Illinois, 405 N.
