Volume save after volume changes
by Ryan Harlich 01 Jul '19

01 Jul '19

Hi Chimera, I am having problems saving changes of volume. Here is my script: 1. open C:\Users\ Desktop\density.map 2. volume #0 level 1.0 3. sel #0 4. volume sel save C:\Users\ Desktop\density2.mrc This does not save the change at line 2. How can I go about to save the change? Best, Ryan Harlich Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10

Saving .pdb file in location of .mrc file
by Ryan Harlich 27 Jun '19

27 Jun '19

Hi Chimera, I am having a bit of difficulty figuring out how to move the location of a map and save it in that location. I am able to move it but when I save and reopen it is back to where it is. I see I can use molmap and use onGrid to achieve this but this overwrites gridSpacing 1 which is crucial as I need to set the resolution to 1. So the problem is when I save a molmap with gridSpacing after performing move cofr and reopen it, it is not in the location of my .mrc. If I use onGrid I cannot achieve gridSpacing 1. An alternative if possible would be to have the .ent/.pdb saved to the new location where the .mrc density map is and reopened to this same location because then I can do the rest from there.

Looking for an image...
by David Cohen 27 Jun '19

27 Jun '19

Hello, Let me preface this by saying that I am not a user of Chimera, I just find the images it creates interesting. My name is Dave and I have a metal band we have named Entropathy. Don't go looking for us on the internet, we aren't anywhere yet, just a bunch of guys in my studio making loud crazy music. The band name is a mashup of Entropy and the suffix "pathy" a condition we have defined as "A degenerative fixation on the ultimate disintegration of all matter". I was surfing the internet looking for some kind of images that would fit as an album cover and came across a few of Chimera's images. I was wondering if you might have some older images sitting around nobody has licensed that might be considered an artistic rendering of molecular entropy. We don't really have any money to spend, but I thought I would reach out and see if you had something that would be of interest to us and would not be an issue to share. Thank you for your time, David Cohen Progammer, Writer, Musician, Dad (not necessarily in that order) djcohen66(a)gmail.com

Re: [Chimera-users] Sudden Chimera issues with OSX Mojave?

You may already know this, but: the latest Tk (8.6.9) doesn't play well with tkinter. Python's solution seems to have been to bundle 8.6.8 with new installs. In my own projects I installed 8.6.8 to regain functionality.

coloring mmCIF files
by Josef Sprinzak 27 Jun '19

27 Jun '19

Dear Chimera Support I am a developer of consurf (http://consurf.tau.ac.il/) for displaying evolutionary conservation of amino/nucleic acid positions in a protein/DNA. Till now we have been working with PDB files and inserting the coloring values in the b-factor (temperature) field in the ATOM part. In the chimera script we use the color commands: color CONS1 @/bfactor=1 color CONS2 @/bfactor=2 color CONS3 @/bfactor=3 ... Now we wish to start using mmCIF files. Where should we insert the coloring values in the mmCIF file, and how do we reference then with the chimera commands ? Best Josef

Sudden Chimera issues with OSX Mojave?
by Neil Rzechorzek 27 Jun '19

27 Jun '19

Dear Chimera users, Has anyone else started seeing issues with the latest stable version of Chimera on OSX Mojave? We have two new identical systems that were running perfectly as recently as 48 hours ago, but now Chimera is constantly crashing whenever we do something as trivial as File>Open or if we attempt to save a map. To our knowledge there has been no update to Mojave, and we haven't changed our Chimera installation. An example of the error log generated by Chimera when trying to, for example, save a map is: while executing "4642906592_scrollBothNow" ("after" script) File>Open windows do not scroll properly, and will instantly crash the entire program unless we change preferences to 'Open dialog starts in directory from last session = false' Does anyone know of any recent (last ~36 hours...) changes to any supporting software? We're wondering whether there has been some silent security update at Apple that has interefered with, for example, the windowing toolkit?

time counter
by CLARA BLANES MIRA 26 Jun '19

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

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
