Select / Structure / secondary structure / turn broken
by Tom Goddard 12 Nov '09

Hi Haixin, I suspect "turn" doesn't just mean not helix and not sheet but I don't know. Others in my lab will know so I've forwarded your question to the Chimera mailing list so they can answer. If you want to select all residues that are neither helix nor sheet you can use the command: select ~ :/isHelix :/isSheet Tom -------- Original Message -------- From: Haixin Sui To: 'Thomas Goddard' Date: 11/6/09 2:27 PM > Tom, > > How have you been? > > This email is to report a small bug I experienced.

coarse-grained MD
by Francesco Pietra 11 Nov '09

11 Nov '09

I know that questions about coarse-grained MD wit amber have already been raised. However, I wonder whether any plan is going on - if feasible at all - to implement in the ambertools something like the cg builder of vmd. Or ask chimera software if a conjoint effort may allow us amber users to approach cd md "at home", benefitting of the amber's secure code. thanks francesco pietra

Hi Ibrahim, I'm glad it helped. I've opened a Trac ticket for your request for restricted rainbow coloring, so you'll get a notification when it gets implemented. It could be quite some time before I get to it, though if others request it also it could happen sooner. --Eric On Nov 9, 2009, at 8:28 PM, Ibrahim Moustafa wrote: > Hi Eric, > > Thank you very much, as usual, I got the help I expected from > chimera team. > > Actually, the conformational change for the structure I have is > dramatic and involves wide range of residues.

Re: [Chimera-users] Coloring range for residues

Hi Ibrahim, Just thought I would mention that there are some other interesting ways to show conformational changes or conformational variability in a single picture. Some images are attached at the bottom. You can assign attributes to residues, and then show those attribute values on one or more structures with color and/or "worms". If two or more structures are associated with an alignment and you show the alignment "RMSD" header, that automatically creates the residue attribute named mavRMSD, where the values are the alpha-carbon RMSDs for residues in the same column of the alignment. If you only have two structures it boils down to the CA-CA distance between the two residues in each column of the alignment. You are probably thinking "but I don't have an alignment!" -- however, in Chimera it is easy to make one. If you have > 2 structures already superimposed, you can use Match->Align (under Tools... Structure Comparison) to create and display the sequence alignment. If you have 2 structures, you can use MatchMaker to both create the pairwise sequence alignment and superimpose the structures. Here is an example with a G protein in the "on" and "off" conformations, using the command version of MatchMaker: open 1tad open 1tnd del ~ :.a mm #0 #1 show true That will create the pairwise sequence alignment with RMSD header shown. Then in the alignment window, choosing "Structure... Render by Conservation" brings up the dialog for mapping colors and/or worm fatness onto the structures. In that dialog, change the attribute from "mavConservation" to "mavRMSD" to see the histogram of values. Then use the Colors or Worms section in the dialog to map the values. You can do it for either or both structures. <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/render/render.html… > I attached images for the example above, where mavRMSD is shown with: (a) worms for both structures (b) color on one structure (c) both color and worms on one structure You could also do the coloring with command "rangecolor" instead of with the dialog <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/rangecolor.html> The example uses two conformations of the same protein, but it will also work with different proteins along as they are similar enough for Matchmaker to create a good alignment. Or instead of using an alignment, you can create your own attribute in a text file and then use "rangecolor" or the "Render by Attribute" tool (under Tools... Depiction), actually the same dialog used above for showing mavRMSD, to show your custom attribute on the structure. There is a description of the file format <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/defineattrib/defin… > and example files <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/defineattrib/defin… > Probably more information than you wanted 8-) Elaine ----- Elaine C.

The surface is obtained by rolling a sphere of a 1.4A radius over the molecule and the surface is all points reached by that rolling sphere. The cusps happen because that sphere does not fit between the residue 36 and 104 HE2 atoms. If you reduce the probe radius to 1.2 A then you get rid of the cusp but the surface is slightly different.

Coloring range for residues
by Ibrahim Moustafa 09 Nov '09

09 Nov '09

Dear Chimera team, I wonder if there is a way to color a certain range of residues using rainbow. I tried to use the rainbow command with atom_spec but it applied for the whole chain. What I want to do is to color part of the structure as a rainbow (from blue-white-red) with an increasing order of residues number. I just wanted to highlight a region of conformational change so the eye can follow which part of the structure has changed dramatically. Thanks in advance for your help. Ibrahim -- Ibrahim M.

Hello, I have been trying to rotate a large volume relative to a reference volume using the vop resample command. The problem is that both volumes are nearly 2GB. However, If I were to bin the volumes (by n) and had access to the rotation R(alpha, beta, gamma) and translation T(x,y,z) matrices I could perform the rotation in an alternate program via R and nT. Thanks! Lori

Dear All, I have a question regarding the contact interactions between a protein-ligand complex. I can retrieve the contacts by the findclash command in --nogui mode as below: chimera --nogui protligcomplex.pdb clash.com and similarly I can find the hbonds. The output I am getting is as below: -------------------------------------------------------------------------------- 32 contacts atom1 atom2 overlap distance LIG 1 H ALA 265.A O 1.045 1.435 LIG 1 O ALA 265.A O 0.550 2.430 LIG 1 N GLU 169.A OE2 0.439 2.666 LIG 1 H GLU 169.A CD 0.116 2.584 LIG 1 O ASN 253.A 1HD2 0.094 2.386 LIG 1 H ALA 265.A C 0.090 2.610 LIG 1 C ALA 265.A O 0.059 3.121 LIG 1 N ASN 253.A OD1 -0.037 3.142 LIG 1 C ALA 265.A O -0.039 3.219 LIG 1 N GLU 169.A HG3 -0.072 2.697 LIG 1 C PHE 168.A HB2 -0.081 2.781 LIG 1 N GLU 169.A CG -0.113 3.438 LIG 1 N GLU 169.A CD -0.125 3.450 LIG 1 N GLU 169.A CD -0.128 3.453 LIG 1 C MET 270.A HG2 -0.140 2.840 LIG 1 N PHE 168.A CD2 -0.163 3.488 .......... .... ... .. . -------------------------------------------------------------------------------- Now I want to further classify these contact interactions into more other types: Aromatic and Ionic (anion < - > cation). Is there any way in Chimera to achieve this? Or if I want to do it with some scripting, which atoms I would say are involved in ionic and aromatic interactions considering the distance value as well? I would be very much grateful if someone suggest me a way to do this. Thanks, Best regards, -- Shahid.

Hi, I am trying to install chimera on Fedora 11 and i am running into problems. After config i tried running make and got the following error. #first i got the error evp.h not found Even though yum said openssl was installed. Anyway i downloaded openssl and tried to install it manually. But i still got the same error. So then i copied the openssl header files folder to /usr/include This got me past this error. #Next i got this error gcc -g -O2 -o sha1_keygen sha1_keygen.o -L/home/ahmad/chimera/src -lchimera -lpthread -lcrypto /usr/bin/ld: cannot find -lcrypto collect2: ld returned 1 exit status make[1]: *** [sha1_keygen] Error 1 I just installed openssl with the default options. Any ideas what i am doing wrong here! Ahmad

I can use the vop resample command in a 64 bit Chimera for Linux and reassign one volumes coordinates relative to the other. However, it is slow to execute, but it does work. In order to speed things up is there a way to bin the volumes (to use less space), place it through the vop resample command, and then un-bin the volume without losing information? Thanks! Lori

Dear all, I'm trying to write a script to interpolate between two structures and save the intermediate conformations as pdb files. I need a script since I have to repeat this procedure several times. As far as importing the structures and interpolating is concerned I have no problem: open A.pdb open B.pdb morph start #0 morph interpolate #1 frames 6 (I need 5 intermediates) What I don't manage to figure out is how to save the intermediate configurations. Figuring out that morph interpolate was generating a trajectory stored as the model #2 I tried write format pdb trajectory #2 out.pdb but it didn't write anything I also unsuccessfully tried with perframe write format pdb out.pdb but I still got no output. Does anybody have any suggestion? Regards Lorenzo Bongini

Tell me there is a segmentation fault at the beginning without any molecule, map or other things. Just exits directly at start up. Friends of mine told me, it will be maybe the wrong graphic driver, but I all ready tried different ones. At the Moment I use nvidia drivers 185.18.14 on a Linux 64 bit system. I have no idea now, so hope someone can help me at this point... Best regards! Mario

Hi Mario, There is no guaranteed way. On the Mac or on Linux you may be able to stop the computation by sending Chimera's Python interpreter an INT signal (terminal interrupt) [I don't know of any such option on Windows]. Open a terminal window (on Mac: /Applications/Utilities/ Terminal.app). Find Chimera's Python process via: ps augxww | grep python You'll see something along the lines of: pett 86576 98.7 13.4 1218088 562256 ?? R 11:58AM 2:17.97 /Users/pett/Applications/Chimera-daily-x11.app/Contents/ Resources/bin/python2.5 /Users/pett/Applications/Chimera-daily-x11.app/ Contents/Resources/share/__main__.py The first number (86576) is the process ID of Chimera's Python interpreter. Send it an interrupt signal by: kill -INT 86576 If all goes well, Chimera will bring up an error dialog saying something about KeyboardInterrupt. The Match->Align computation will have stopped with the structures in the same position as they were at the end of the last iteration, the last alignment window will be up, and the Reply Log will be available. On Linux, if you started Chimera yourself from the command line you may be able to just hit control-C (or whatever your interrupt character is) instead of the rigamarole above. --Eric On Oct 27, 2009, at 11:46 AM, Mario Borgnia wrote: > Hi Eric, > > Thanks for the fast response.

Chimera slow on Win 7 64-bit system

Hi Wen, The slow ribbon and atom rendering must be a graphics driver issue. Surfaces use different OpenGL calls for rendering allowing them to be fast. You can try updating your graphics driver. If you have the most recent you could try poking around with graphics driver settings that trade of speed and quality. We don't have a 64-bit Windows Chimera. Only 64-bit Linux Chimera is available. We'll probably put out a 64-bit Mac Chimera in about 6 months and 64-bit Windows Chimera in about 1 year.
