Working with Electron density map

Dear Chimera user's I am trying to super impose molecular dynamics calculated density on cryo EM density and then slice densities to visualize each in different colors. I fitted density successfully now during slicing their X Y Z co-ordinate is not matching. The similar analysis were publish in Marzinek et al., 2016, Structure 24, 1–11 August 2, 2016 http://dx.doi.org/10.1016/j.str.2016.05.014 Please see figure 3 for more details and image attached here.

Issue with docking in chimera and autodock vina
by Miss Charles 02 May '17

02 May '17

Dear Chimera Team, I have been trying to dock the small molecules pino-stilbene and trans-stilbene to chainA of the estrogen receptor on chimera using autdick vina. Suddenly, with almost no changes to my protocols I have been getting error message 13 permission of pino-stilbene denied or error message 134 permission of trans-stilbene denied. What am I supposed to do to avoid getting that error message? Thank you so much for your time and your help. Sincerely, Alexis Charles

assistance

I asked this question several months ago, but rarely have applied the answer. I have a structure that has a long stretch that is disordered. In the structure it appears as a dashed line. If I highlight this section of the total sequence and then apply a color (red) the whole structure is then colored red. So how can I make the dashes slightly larger, and secondly color that stretch of dashes with a particular color without coloring the rest of the molecule? Thank you Arthur G. Szabo

In the effort to create a more integrated pipeline with vastly used 3d software (I use mainly C4D and modo) is there a way to export animation from chimera in a format that other software can interpret. To make an example. If I wiggle a molecule in chimera, can I export the animation in a format that does not lot this info ? And eventually are there plan to create this feature in chimeraX ? > Giorgio Hi Giorgio, Chimera supports several export formats, see “File… Export Scene” in the menu or the “export” command. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/export.html> <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/export.html> However, these are for individual conformations, not for a whole animation, so you’d have to export at each step. Although ChimeraX is in early development, currently the “save” command formats include STL and X3D. The command “save formats” lists all the formats that can be saved. <http://rbvi.ucsf.edu/chimerax/docs/user/commands/save.html> These may be subject to the same limitations mentioned in the Chimera manual links above. I hope this helps, Elaine ---------- Elaine C. Meng, Ph.D. UCSF Computer Graphics Lab (Chimera team) and Babbitt Lab Department of Pharmaceutical Chemistry University of California, San Francisco

independent rotation of multiple models
by Stefano Luciano Ciurli 01 May '17

01 May '17

Hello, if I have more than one structure in the same session, is there a way to rotate all models together along their respective axes (for example their intrinsic y-axis) without having to do so after selecting each individual model from the model panel? Regards and thanks, Stefano Ciurli
