Help in validation of Mutant Structure
by carlo cast 20 May '19

20 May '19

Good Morning to everyone, it’s my first time here writing at you, I hope I’m doing right. The point is that I’m working with a wild type enzyme from which I got mutant versions by using swap aa command. My goal is to look at the effects that mutations have on the structure by superimposing the mutant form with the wild type one. When I perform matchmaker command, RMSD is equal to 0 and the structures overlap perfectly; thus I thought to minimize structure before superimposing and in this way I see a little difference in RMSD but it could be due to the different steps of the minimize process (e.g. adding protons) than the actual effect of mutations. Moreover when I perform multiple sequence alignment, the amminoacids I swapped actually are not different from the Wild type ones. If I point the cursor on the swapped aa I see the difference in name and side chain but by doing multiple sequence alignment they do not appear. Any suggestions?

Re: [Chimera-users] Contact area between 2 Proteins
by Elaine Meng 17 May '19

17 May '19

Dear Fer Villa, (better to send questions to chimera-users(a)cgl.ucsf.edu, CC’d here) It is not really a matter of right and wrong. Instead it depends on what you want… If you want to measure buried solvent-accessible and solvent-excluded surface areas of atomic structures, use “measure buriedArea”. The “measure contactArea” command is similar but if the goal is measurement (rather than coloring for a figure), it is generally used for other kinds of surfaces that are not necessarily associated with any atoms, like density map isosurfaces. In that case, the appropriate cutoff value really depends on the judgment of the user based on what kinds of surfaces these are and what the user is trying to do. The tutorial you mention is for making a figure where the interaction surfaces of two proteins are colored, which is a different purpose than getting a measurement value. It explains that different cutoffs could be used with “measure contactArea", but the example has 2.5 because it gave similar appearance to using the other (buriedArea) method. The tutorial shows both methods because if you are making a figure, you could use either one as you like. It actually discusses three methods. For the other people on the list, here is that tutorial: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/openbook.html> … 3 methods of coloring the interface: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/openbook.html#in…> I hope this helps, Elaine ----- Elaine C.

display bond lengths and angles
by Thomas Evangelidis 17 May '19

17 May '19

Hello, Is it possible to load a small molecule in Chimera and display all bond lengths and angle values, pretty much as you can do using labelopt option for the atom names? If not directly, could you please give me some hints about how to write a Python script to do it? I thank you in advance for your help.

Still won't work after libfreetype.so* and libz.so* removal
by Яцкевич Максим 14 May '19

14 May '19

Hi! I am running Fedora 29. Now I'm trying to install chimera-1.13.1-linux_x86_64.bin. After successful installation it failed to create a window in a desktop applecation menu. So I followed the instructions on the web-site (http://www.cgl.ucsf.edu/chimera/data/downloads/1.13.1/linux_x86_64.html). After running the command <dir_name>/bin/xdg-setup install it stumbled upon the same error that was discussed in this thread (https://www.cgl.ucsf.edu/pipermail/chimera-users/2018-November/015237.html) Traceback (most recent call last): File "/home/sec/.local/chimera/share/__main__.py", line 73, in <module> value = chimeraInit.init(sys.argv) File "/home/sec/.local/chimera/share/chimeraInit.py", line 666, in init import chimera File "/home/sec/.local/chimera/share/chimera/__init__.py", line 2777, in <module> from SimpleSession import BEGIN_RESTORE_SESSION, END_RESTORE_SESSION File "/home/sec/.local/chimera/share/SimpleSession/__init__.py", line 14, in <module> from save import saveSession, sessionID, noAutoRestore, autoRestorable, \ File "/home/sec/.local/chimera/share/SimpleSession/save.py", line 13, in <module> from chimera import replyobj, selection, SessionPDBio, version File "/home/sec/.local/chimera/share/chimera/replyobj.py", line 24, in <module> import Tkinter File "/home/sec/.local/chimera/lib/python2.7/lib-tk/Tkinter.py", line 39, in <module> import _tkinter # If this fails your Python may not be configured for Tk ImportError: /usr/lib64/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var So I followed your advise and removed the corresponding files: > rm ~/.local/chimera/lib/libz.so* > rm ~/.local/chimera/lib/libfreetype.so* Unfortunately it didn't solve the problem. So after typing: > ~/.local/chimera/bin/xdg-setup install It complained that it cannot find the libz.so file!

Upload color scheme

I am looking for a 3D protein viewer that allows me to visualize the protein tertiary structure using my own color assignments, for each residue (or alpha carbon). In other words I would upload a file, with a value for each residue, which would drive the color assignments. Thx

Re: [Chimera-users] Non-standard atom names

Hi Eric So I have been only using dock6 for docking and now want to venture in using dock3. I tried checking online for tutorials that I could look at but there are just a couple of them. On the UCSF website, there is a tutorial but requires the use of dock blaster. I just have a few questions; Is there another way of using dock3.6 without using dock blaster? Is there another simpler tutorial for dock3.6 that you could recommend me to use? Are the dock 3.6 steps similar to the steps of dock6?

I recommend using the Dock Prep tool (Tools→Structure Editing→Dock Prep), which will use a rotamer library to fill out missing/incomplete side chains before adding hydrogens and assigning charges. Use the dialog check boxes to turn off any Dock Prep steps you don’t want (e.g. Write Mol2 file). Applying a lot of rotamers takes a few minutes, so you might want to bring up the Reply Log first (Favorites→Reply Log) so you can keep an eye on the Dock Prep progress while you possibly do something else. > > ―Eric > > Eric Pettersen > UCSF Computer Graphics Lab > >> On Apr 11, 2019, at 8:26 PM, Sid Majaha <sidumomajaha(a)live.com <mailto:sidumomajaha@live.com>> wrote: >> >> >> Hi Eric >> >> Problems with atom names in adding charge to a receptor using Chimera v1.13.1 >> (ToolsàSurface Binding/AnalysisàAdd charge) >> I first added my H to prepare my receptor.
