Chimera morph colors with morph conformations
by Ahmad Khalifa 28 Sep '18

28 Sep '18

Hello, I'm trying to create a movie with morph conformations. I wonder if it's possible to morph the colors, or change colors midway through, going from one conformation into the other. Please feel free to contribute any ideas or thoughts on how to make my movie clearer and more visually aesthetic. Thanks.

Loading multiple ligand mol2 files for AV
by Leif Peterson 26 Sep '18

26 Sep '18

Is it possible to load multiple mol2 files, and add H, equlibrate charges, then energy minimize all if the ligands in batch mode, then save all of them to pdbqt files? Then, loop through all of the ligands using AV on each to get sorted docking results. Reason I ask is because almost all resources available on multiple ligand use with AD and AV seem outdated, developers moved on, and am hitting dead ends and pages not found.

Hi, I am new to chimera. I want to superimpose a domain for the two protein molecules and get the rmsd for the non superimposed protein parts. How should i do it. Ihave superimposed domain of interest for my protein using match, but now i am not getting how to proceed further. Thanks Vani Pande Int PhD Biological sciences IISER Pune 20162013

While the command line equivalent to show is "modeldisplay #modelnumber", what is the equivalent for hide? Regards.

Re: [Chimera-users] [chimera-dev] Auto set threshold boundaries and colors

Hi Benjamin, This only refers to intiial display. You can of course change the threshold (isosurface level) to whatever is appropriate for the specific data, by dragging the vertical bar in the Volume Viewer histogram or by using the “volume” command. It is not a preference, but you could create an alias that would be listed in the menu so that you could reapply it easily. For example, command: alias ^orbitals volume all level 0.05 color pink style surface … or there could be multiple levels and colors specified in the same command. Then your alias “orbitals” (or whatever you named it) would be listed in a top-level Aliases menu for easy reapplication to later datasets. I.e., choosing menu: Aliases… orbitals or typing the command “orbitals” would run it. Aliases are saved in the preferences: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/alias.html> The volume command has many options: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/volume.html> The 1% initial display (rather than a specific threshold value) was most useful for the wide variety of volume data where people often do not know what threshold will be best for viewing. It is surely adjustable by changing the code but others would have to advise on that matter. I hope this helps, Elaine ----- Elaine C.

Fitmap: correlation about the mean for global search
by Michele Lunelli 25 Sep '18

25 Sep '18

Dear people, I want to do a global search of an atomic model into an EM map, using the correlation about the mean (cam) as metric. I use a command like this: fitmap #0 #1 resolution 6 metric cam search 100 radius 150 However, only the correlation about zero is reported in the final fit list (and used to rank the solutions). Where can I find the cam values for all the fits? Thank you Michele

MatchMaker

Hello, I used MatchMaker to superimpose a couple of models. Now when I open any .pdb files, they automatically superimpose. How can I "turn off" MatchMaker so it doesn't automatically superimpose everything? Thanks, Leanne M. Leanne Ward, MEd.

Hiding AutoDock Vina Search Volume (frame)
by leifepeterson＠sbcglobal.net 24 Sep '18

Using Select-->Chains-->(no ID), I can select the AutoDock Vina Search Volume structure after performing a docking, but once it's selected (highlighted in green), I can't seem to remove it from the molecular plot. What is the recommend way to remove the square frame?
