Hi, I've docked a ligand with a receptor and I get a pdb with1 chain (chain A) I'd like to separate recpetor-ligand in two different chians (chain A e chain B). How can I do that in Chimera? regards

Hi, I'm trying to model a TM protein using a Fugue approach. This method involves to divide a transmembrane protein in fragment (Nter, TM1,LOOP1and so on) Each fragments is predicted separatly. I'd like to assembly and join fragment, superimposing the backbone of a fragment with that of the correspondent segment in the structure of my protein. How can I achieve this goal with Chimera? regards

Re: [Chimera-users] Chimera: Myosin thick filament movie
by Tom Goddard 28 Apr '11

28 Apr '11

Hi Rogelio, The myosin thick filament movie in the Chimera animation gallery was made in 2006 using a 700 line python program I wrote. Fortunately Chimera animation capabilities are much better now, so I've made a Chimera command script that makes the same movie in Chimera 1.5.2 (Jan 2011), about 150 commands. I've attached the script. It of course requires the myosin data files to work. So I've put the script and data files in myomovie.zip and put a link to that in the animation gallery with the myosin animation (will appear after web site is rebuilt tonight). http://www.cgl.ucsf.edu/chimera/animations/animations.html To create the movie you open the myomovie.py Chimera session then open the myomovie.cmd command script. Rendering this movie takes about 15 minutes (for about 70 seconds of final video, 1760 frames) using the high quality supersample 3 option set in the script. The myosin movie is somewhat complex. There are about a half dozen simpler movie making command scripts with links on the animation gallery page. We don't have a separate movie scripts web page, although that is a nice idea. There is a movie making tutorial on the Chimera tutorials page http://www.cgl.ucsf.edu/chimera/tutorials/tutorials.html and there are details about all the commands in the Chimera User's Guide http://www.cgl.ucsf.edu/chimera/current/docs/UsersGuide/movies.html Tom > Hi Tom, > > I have been recently looking at the animation gallery of Chimera and I > was wondering if I could get a copy of the script used to make the > Myosin movie, > Do you guys have a repository of scripts used for the displayed movies? > > I am working with a helical map and I would like to try to implement a > similar animation for my maps, > > thanks a lot for your help and consideration > > ROGELIO > > > -- > Rogelio A.

how to write log file in Chimera
by Rogelio A. Hernandez-Lopez 28 Apr '11

28 Apr '11

Hi, Is there any way to create a log file to store all the actions performed by the user during a chimera session, either using the menus or command line? I want to write a script for a movie and it would be very useful to copy and paste commands from such as file thanks, ROGELIO -- Rogelio A.

trying to add charges
by Irene Newhouse 27 Apr '11

27 Apr '11

I'd like to do a PDB2PQR run of my protein with its 'ligands' - actually substrates & am having problems getting the server to recognize my mol2 file. So I thought I'd use chimera to add charges & write, hopefully, a compatible mol2 file. I'm having problems with that as well. This is a pdb of the ligands:HETATM 8225 MG MG A 291 25.874 25.146 58.617 1.00 0.00 Mg2+ HETATM 8226 C4 FPS A 292 25.754 19.949 62.737 1.00 0.00 C HETATM 8227 C3 FPS A 292 26.088 21.273 63.475 1.00 0.00 C HETATM 8228 C2 FPS A 292 26.021 22.571 63.132 1.00 0.00 C HETATM 8229 C1 FPS A 292 25.656 23.447 61.998 1.00 0.00 C HETATM 8230 S1 FPS A 292 27.204 24.181 62.219 1.00 0.00 S HETATM 8231 P1 FPS A 292 27.928 23.762 60.771 1.00 0.00 P HETATM 8232 O1 FPS A 292 28.873 24.955 60.385 1.00 0.00 O HETATM 8233 P2 FPS A 292 28.554 26.180 59.405 1.00 0.00 P HETATM 8234 O2 FPS A 292 28.206 25.713 57.968 1.00 0.00 O HETATM 8235 O3 FPS A 292 27.331 26.943 59.830 1.00 0.00 O HETATM 8236 O4 FPS A 292 29.622 27.136 59.149 1.00 0.00 O HETATM 8237 O5 FPS A 292 26.862 23.528 59.683 1.00 0.00 O HETATM 8238 O6 FPS A 292 28.976 22.661 61.190 1.00 0.00 O HETATM 8239 C5 FPS A 292 26.754 21.192 64.778 1.00 0.00 C HETATM 8240 C6 FPS A 292 26.118 20.990 66.155 1.00 0.00 C HETATM 8241 C7 FPS A 292 27.084 20.015 66.840 1.00 0.00 C HETATM 8242 C8 FPS A 292 28.144 20.342 67.618 1.00 0.00 C HETATM 8243 C9 FPS A 292 28.586 21.777 67.991 1.00 0.00 C HETATM 8244 C10 FPS A 292 28.618 19.212 68.506 1.00 0.00 C HETATM 8245 C11 FPS A 292 27.622 19.162 69.634 1.00 0.00 C HETATM 8246 C12 FPS A 292 27.899 18.054 70.615 1.00 0.00 C HETATM 8247 C13 FPS A 292 28.127 18.187 71.942 1.00 0.00 C HETATM 8248 C14 FPS A 292 28.131 19.492 72.723 1.00 0.00 C HETATM 8249 C15 FPS A 292 28.358 16.835 72.549 1.00 0.00 C HETATM 8250 H4 FPS A 292 24.677 19.881 62.580 1.00 0.00 H HETATM 8251 H5 FPS A 292 26.263 19.931 61.773 1.00 0.00 H HETATM 8252 H1 FPS A 292 25.472 22.838 61.113 1.00 0.00 H HETATM 8253 H11 FPS A 292 24.694 24.092 62.300 1.00 0.00 H HETATM 8254 H14 FPS A 292 28.310 18.659 67.618 1.00 0.00 H HETATM 8255 H15 FPS A 292 29.626 18.910 68.790 1.00 0.00 H HETATM 8256 H141 FPS A 292 28.344 19.287 73.772 1.00 0.00 H HETATM 8257 H142 FPS A 292 28.897 20.155 72.320 1.00 0.00 H HETATM 8258 H143 FPS A 292 27.155 19.970 72.638 1.00 0.00 H HETATM 8259 H91 FPS A 292 29.470 21.732 68.628 1.00 0.00 H HETATM 8260 H92 FPS A 292 28.821 22.333 67.083 1.00 0.00 H HETATM 8261 H93 FPS A 292 27.779 22.279 68.525 1.00 0.00 H HETATM 8262 H7 FPS A 292 26.852 18.977 66.652 1.00 0.00 H HETATM 8263 H61 FPS A 292 26.054 21.948 66.670 1.00 0.00 H HETATM 8264 H62 FPS A 292 25.117 20.575 66.036 1.00 0.00 H HETATM 8265 H51 FPS A 292 27.451 20.354 64.779 1.00 0.00 H HETATM 8266 H52 FPS A 292 27.298 22.117 64.967 1.00 0.00 H HETATM 8267 H4 FPS A 292 26.087 19.103 63.338 1.00 0.00 H HETATM 8268 H12 FPS A 292 27.905 17.074 70.162 1.00 0.00 H HETATM 8269 H151 FPS A 292 28.547 16.946 73.646 1.00 0.00 H HETATM 8270 H152 FPS A 292 27.455 16.195 72.388 1.00 0.00 H HETATM 8271 H153 FPS A 292 29.246 16.355 72.064 1.00 0.00 H HETATM 8272 H111 FPS A 292 27.646 20.103 70.183 1.00 0.00 H HETATM 8273 H112 FPS A 292 26.622 19.003 69.230 1.00 0.00 H HETATM 8274 H2 FPS A 292 26.305 23.333 63.843 1.00 0.00 H HETATM 8348 O3 IPE A 586 21.257 22.023 59.139 1.00 0.00 O HETATM 8349 C1 IPE A 586 21.725 22.610 60.331 1.00 0.00 C HETATM 8350 C2 IPE A 586 21.891 21.539 61.401 1.00 0.00 C HETATM 8351 C3 IPE A 586 22.135 21.746 62.732 1.00 0.00 C HETATM 8352 C4 IPE A 586 22.476 23.125 63.351 1.00 0.00 C HETATM 8353 C5 IPE A 586 22.090 20.534 63.651 1.00 0.00 C HETATM 8354 P1 IPE A 586 22.541 22.279 58.101 1.00 0.00 P HETATM 8355 O1 IPE A 586 23.289 23.718 58.505 1.00 0.00 O HETATM 8356 O2 IPE A 586 23.635 21.031 58.224 1.00 0.00 O HETATM 8357 O7 IPE A 586 21.980 22.381 56.596 1.00 0.00 O HETATM 8358 P2 IPE A 586 22.517 20.944 55.933 1.00 0.00 P HETATM 8359 O4 IPE A 586 24.120 21.122 55.494 1.00 0.00 O HETATM 8360 O5 IPE A 586 22.398 19.740 57.082 1.00 0.00 O HETATM 8361 O6 IPE A 586 21.597 20.552 54.601 1.00 0.00 O HETATM 8362 H6 IPE A 586 20.970 20.939 61.359 1.00 0.00 H HETATM 8363 H7 IPE A 586 22.711 20.896 61.047 1.00 0.00 H HETATM 8364 H4 IPE A 586 22.660 23.213 64.432 1.00 0.00 H HETATM 8365 H5 IPE A 586 22.534 24.017 62.710 1.00 0.00 H HETATM 8366 H1 IPE A 586 21.090 20.076 63.606 1.00 0.00 H HETATM 8367 H2 IPE A 586 22.843 19.801 63.329 1.00 0.00 H HETATM 8368 H3 IPE A 586 22.303 20.848 64.684 1.00 0.00 H HETATM 8369 H11 IPE A 586 22.687 23.089 60.148 1.00 0.00 H HETATM 8370 H12 IPE A 586 21.008 23.356 60.675 1.00 0.00 H END When I try to add charges, chimera chews on it for a bit, then gives me a message that amber has stopped running, check the log file. When I click on the log file, the only message is that I've had a crash. In the older version of chimera I was running, I also tried this with only the IPE & got the same behavior. Are my compounds just too nonstandard? Thanks! Irene Newhouse

3D labels
by matheus froeyen 26 Apr '11

26 Apr '11

Dear all, I try to change the size of the 3D labels in my structure via the preferences/background menu but there is no effect! Strange but changing the font type & bold, italic etc works. I tried a previous version of chimera and there I have the same problem. The font is always small (about 12?) The 2D labels I can change font size without problem. But I know it has worked before. I have no idea what is going on. I work on A Macintosh G5 with Leopard. Thanks for any suggestions mathy

hello, i was wondering, whether there is a way to make the 2d labels appear slowly, stepwise (meaning, through some rounds of opacity to the normal text) ? best regards, jean-paul
