Cartoon smooth loops chimX
by Dominik Hrebík 19 May '20

19 May '20

Hi all! Is there any possibility to smooth loops in cartoon representation in ChimeraX? I can't find it in the user guide. Something similar to pymol's cartoon_smooth_loops,1: https://pymolwiki.org/index.php/Cartoon_smooth_loops Best, Dominik -- ################################## Dominik Hrebik Laboratory of Structural Virology CEITEC, Masaryk University Kamenice 5 / A35 Brno, 625 00, Czech Republic Phone: +420 549 49 7764 <%2B420%20549%2049%207756> ##################################

Focus in ChimeraX
by Luca Pellegrini 18 May '20

18 May '20

Hi, What is the ChimeraX equivalent to the Focus command in Chimera? I have selected a portion of a structure, and would like to bring it into focus without dragging it into view. Also Focus would automatically set the selection as the pivot point. Best wishes, Luca Luca Pellegrini, PhD Department of Biochemistry University of Cambridge Cambridge CB2 1GA lp212(a)cam.ac.uk

Turntable rotation
by Scott, Brandon L. 16 May '20

16 May '20

I would like to create an animation where the camera is spun around at a constant azimuthal angle so the object appears to spin on a tabletop. Currently, when I use roll, when it spins to the backside I see underneath the model rather than remaining on top. Any help is greatly appreciated. -Brandon ____________________ Brandon Scott, PhD CZI Imaging Scientist, Research Assistant Professor SDSMT, Nanoscience and Nanoengineering

Re: [chimerax-users] transition from Chimera
by Tom Goddard 15 May '20

Hi Jerome, Putting that "open instructions,html" in your startup preferences is a nice way to show an HTML interface that could have links that execute commands in ChimeraX. I had not thought of that use.

ChimeraX accepts files dragged and dropped on the application. On macOS (and probably Linux and Windows) I should be able to run a shell command that says drop this file on ChimeraX. On Mac the shell command looks like > > % open -a /Applications/ChimeraX.app ~/Downloads/ChimeraX/PDB/1a0m.cif > > That worked for starting ChimeraX and showing the first file. But when I run it again to open a different it merely raised ChimeraX and did not open the new file. That is a bug. I've made a bug report for it. I don't know the equivalent commands on Linux and Windows and whether the would work. > > Tom > > > On May 12, 2020, at 1:50 AM, Jerome Mutterer <jerome.mutterer(a)ibmp-cnrs.unistra.fr <mailto:jerome.mutterer@ibmp-cnrs.unistra.fr>> wrote: > > Dear all, > I'm trying to transition from Chimera to ChimeraX, but my workflow relies on passing scripts to an open, with GUI, instance of Chimera using --send > https://www.cgl.ucsf.edu/chimera/docs/UsersGuide/options.html#send <https://www.cgl.ucsf.edu/chimera/docs/UsersGuide/options.html#send> > > I see that this is not described here: > https://www.rbvi.ucsf.edu/chimerax/docs/devel/apps/ChimeraX/ChimeraX.html <https://www.rbvi.ucsf.edu/chimerax/docs/devel/apps/ChimeraX/ChimeraX.html> > > Is that still available somehow in ChimeraX? > Thanks for any input. > Sincerely, > Jerome. > > -- > Jerome Mutterer > CNRS - Institut de biologie moléculaire des plantes > 12, rue du Général Zimmer > 67084 Strasbourg Cedex > www.ibmp.cnrs.fr <http://www.ibmp.cnrs.fr/> > > _______________________________________________ > ChimeraX-users mailing list > ChimeraX-users(a)cgl.ucsf.edu <mailto:ChimeraX-users@cgl.ucsf.edu> > Manage subscription: > https://www.rbvi.ucsf.edu/mailman/listinfo/chimerax-users

Stuck on one XML-RPC command
by Mungo Carstairs (Staff) 14 May '20

14 May '20

Any XML-RPC fans who can help me with this please? This label command works in the PyMOL command line: label 4zho//A/36/CA 4zho//B/36/CA, "hello world" How do I format an equivalent XML-RPC request? I've tried <methodCall> <methodName>label</methodName> <params> <parameter> <value>4zho//A/36/CA 4zho//B/36/CA</value> </parameter> <parameter> <value>"hello world"</value> </parameter> </params> </methodCall> but get back a fault response XML message with <class 'SyntaxError'>:invalid syntax (<string>, line 1) I have also tried encoding the " as %22, or omitting the quotes, same result. Any ideas please?

Stereo and VR support
by Gökhan Tolun 13 May '20

13 May '20

Hi, Would it be possible to make the graphics window undockable, too, Like the other ones? This would allow the use of stereo monitors with SBS and tb support, which does not work currently with menus, etc. surrounding the graphics window. Also, will you implement DTI stereo as in Chimera? By the way, if theres a way of making ISOLDE work in VR, thatd be great! Thanks, Gökhan

pyqtchart
by Anthony James Schaefer 13 May '20

13 May '20

Hello, I'm interesting in using pyqtchart (https://pypi.org/project/PyQtChart/) as an alternative to matplotlib for some plots in my bundle (I like the default style better, it resizes better - small things like that). If I list pyqtchart as a dependency in my bundle_info.xml like ... <Dependencies> <Dependency name="pyqtchart"/> </Dependencies> ... a new version of PyQt5 gets installed in the directory where bundles get installed. The QChart module from pyqtchart gets installed in this new PyQt5 package. I can't use the QChart module because it's not in the PyQt5 that ChimeraX uses. Is there anything I can do with my bundle to get it to install a usable pyqtchart? Thanks, Tony

wrong version in download
by Christine Gee 13 May '20

13 May '20

Dear ChimeraX I downloaded what was supposed to be chimeraX 0.5 from your site, and 0.1 instead. I have an older mac with an older OS (10.11.6) and would like the last version that was developed for it. Can you please let me know where I can download 0.5? Also does it work with isolde?

Manual segmentation in ChimeraX
by Pattana Jaroenlak (Michael) 13 May '20

13 May '20

Hello, I saw the twitter post from ChimeraX on segmentation of EM serial images ( https://twitter.com/ucsfchimerax/status/1260425173238415360?s=12) It was very beautiful. I have serial section EM images. I am wondering that can I do manual segmentation on ChimeraX? Some cellular features on my images can not be picked up by thresholding or watersheding.

Renaming chain IDs
by Fahrenkamp, Dirk 12 May '20

12 May '20

Hi ChimeraX team. I am happily using chimeraX along with ISOLDE for modelling. Lately, I am running into issues with complexes having too many chains to be handled by the standard .pdb format which is why I am using .cif now. Is there a smooth way/command to rename chain IDs and change _entity.pdbx_description _struct_asym.entity_id accordingly? Thanks! Kind regards, Dirk -- Dr. rer. nat.
