time counter

Dear chimera users, I have two doubts regarding per-frame actions: 1) I am trying to add a counter in my script (commands script, no python script). It works when I do it as a per-frame action in the MD Movie window (just as Elaine does in the’Trajectory and ensemble Analysis Tutorial’) but I am not able to do insert it in my command script: Something like this: movie record 2dlabels create timer text “frame 0" size 40 color white alias ^actions 2dlabels change timer text "frame <FRAME>" perframe actions; coordset #0 1,216000,1000 load false; wait 216; ~perframe movie encode movie.mp4 2) What I really want is to show nanoseconds, not frames. In my case 1000 frames = 1 ns. When I write frame <FRAME>/1000 in MD Movie window, obviously, it does not work. Any suggestion to make it work and insert it in the commands script? Thank you very much!, Clara

installing vintage chimera
by Francesco Pietra 25 Jun '19

25 Jun '19

Hello Although, as a chimera user, i use the latest linux release, I was also interested to install chimera-1.1442-linux.exe francesco@vaio64:~/tmp$ chmod 755 chimera-1.1442-linux.exe francesco@vaio64:~/tmp$ ./chimera-1.1442-linux.exe bash: ./chimera-1.1442-linux.exe: No such file or directory francesco@vaio64:~/tmp$ ls -ls 20420 -rwxr-xr-x 1 francesco francesco 20909040 Jun 25 10:59 chimera-1.1442-linux.exe I also tried chimera-1.1602-linux.exe and chimera-1.5-linux.bin with the same problem. I must confess that I am quite confused about that. In contrast, no problem with the current stable version for linux. Thanks for advice francesco

full pdb path
by petra wendler 24 Jun '19

24 Jun '19

Dear All, I have a silly question. Having opened a three year old chimera session, I unfortunately have no clue which pdbs on my computer the pdb names in my session refer to (pdbs in session are renamed). Is there a way to somehow open the session in a verbose manner or get the full path of the session pdbs?

segment and group density together
by Yangqi Gu 21 Jun '19

21 Jun '19

Hi Chinera users, I have a density map of a filament. After I segmented the map, I want to group all the outer globular domain (which is part of a monomer) together. Instead of group them one by one, is there a quicker way to do this? I have the helical symmetry of the filaments. Best, Yangqi -- Yangqi Gu Graduate Student Malvankar Lab Yale University, West Campus

chimera help in spacing out two structures within the same session
by #LAI KEI ONN# 21 Jun '19

21 Jun '19

Dear Chimera team would appreciate if you have any advice in spacing out two/or more structures within the same chimera session (e.g. the green structure away from the beige ones) so as to clearly visualise the intercrosslinks (red and blue sticks) between two different structures. Currently everything is superimposed with one another and i tried separating all the structures into different sessions and recombining it again but it didnt work. I am using xlinkanalyzer plugin with chimera. Would appreciate your kind advice, [cid:a79ad9c6-047a-493c-abc9-3ac3d537f4df] thank you!

Chimera - mask after vop
by Ryan Harlich 18 Jun '19

18 Jun '19

Hi Chimera team, Is it possible to mask after vop. I got it to work in Chimera’s command line in the gui but when I run it from my python script it does not work. I am trying to change this working solution to this solution without ground truth: WORKING SOLUTION #chimera_script.write('open ' + paths['input'] + '\n' # 'open ' + paths['ground_truth'] + '\n' # 'molmap #1 6 gridSpacing 1\n' # 'volume #1.1 level 0.1\n' # 'mask #0 #1.1\n' # 'vop resample #2 onGrid #1.1\n' # 'volume #3 save ' + paths['cleaned_map']) NEW SOLUTION chimera_script.write('open ' + paths['input'] + '\n' 'vop gaussian #0 sDev 2\n' 'vop median #1 iterations 5 modelId #2.1\n' 'volume #2.1 level 0.1\n' 'mask #0 #2.1\n' 'vop resample #3 onGrid #2.1\n' 'volume #4 save ' + paths['cleaned_map']) While mask after vop works with GUI command line it gets a NoneType error when doing this: subprocess.run(['/usr/local/bin/chimera', '--nogui', chimera_script.name]). It seems like this might be a bug of chimera? Since it tries to return None to a tuple and crashes. For some reason no triangles in the new surface with vop. Here is a snippet from the depthmask.py where it crashes. [cid:image001.png@01D525AB.830ADC20] Thank you, Ryan Harlich Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10

Chimera local resolution color
by Dmitry Semchonok 14 Jun '19

14 Jun '19

Dear colleagues, I have a cryo-em map after resmap local resolution. I would like to see not just the 2D colored slices but the hole model (not in the movie mode). How to color the model model in chimera based o remap? I would like the final result be similar to https://discuss.cryosparc.com/t/view-coloured-3d-map-in-chimera-using-outpu… <https://discuss.cryosparc.com/t/view-coloured-3d-map-in-chimera-using-outpu…> Thank you.

Hi all, What stereo setup are people recommending these days? It seems that NVIDIA has discontinued the 3D Vision 2 goggles+emitter. Is there something else that is available and works well? Thanks for any advice! -Jonathan
