Morph movie issue
by Kang, Yanyong 28 Oct '13

28 Oct '13

Dear Chimera developer, I have some problem for making morph movie. My start model has the secondary structure, but the final model loses most of the secondary structure. My morph movie could not show the secondary structure transition of the protein structure. If I change final model as the start model, the start model is as the final model. Secondary structure is the same with the start model. Do you have any ideas to solve this issue? Thank you very much Best, Yanyong Dr. Yanyong Kang Laboratory of Structural Sciences Van Andel Research Institute Tel, 616-234-5446

rotation of the molecule using plane and the axis ?
by Marek Maly 25 Oct '13

25 Oct '13

Hello, if I define plane "p" using 3 atoms of the given molecule, is there any possibility to rotate consequently molecule into the position in which the chosen axis of the coordinate system (x or y or z) is perpendicular to the plane "p" ? (Of course except slow and not accurate "manual" rotation by mouse). Than you, Best wishes, Marek -- Tato zpráva byla vytvořena převratným poštovním klientem Opery: http://www.opera.com/mail/

can get sequence from UniProt website
by Elaine Meng 25 Oct '13

25 Oct '13

Hi Pavithra, I forgot to mention that you could just go to the UniProt web site and save the sequence as a file, then open the file in Chimera. For example, I went to UniProt, searched for oprd_human, then in the Sequences section of the oprd_human page, clicked "FASTA" to get to the URL below, contents of which you can save as plain text file named ending in .fa or .fasta and then open in Chimera with File... Open. <http://www.uniprot.org/uniprot/P41143.fasta> It would not have the annotations mentioned in the comparative modeling tutorial, but those aren't important for doing the tutorial. After opening the FAST file as described above, you can then carry on with the tutorial starting with the fourth paragraph in the "Blast Search for Templates" section ("The next step...". <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/dor.html> Best, Elaine ----- Elaine C.

by Pu Qian 25 Oct '13

25 Oct '13

Hi, I upgraded my mac to 10.9 Marvericks. Chimera does not show up input text in Command windows or other text windows properly. I'm using version 1.9, 2013-10-24, 64-bit for mac OSX. It would be a great appreciated if you could tell me which version I should use for this new OSX. Thanks. Best regards Pu Qian The University of Sheffield, UK

Dear chimera users, I'm trying comparative modeling tutorial in chimera tutorials and I'm getting the following error in using fetch uniprot id. *Steps followed: * Menu--> fetch by ID--> selected uniprot--> "oprd_human" "P41143" (tried all combinations) *Error:* *BadStatusLine: '' File "C:\Program Files\Chimera 1.7\bin\lib\httplib.py", line 371, in _read_status raise BadStatusLine(line) See reply log for Python traceback. * I tried changing the preference to use "http" but nothing fix it. please help. -- regards, Pavithra.K.B.

Typing broken in Mac Mavericks (10.9) with 64-bit Chimera
by Tom Goddard 24 Oct '13

24 Oct '13

With the new Mac operating system Mavericks (Mac OS 10.9), typing into Chimera entry fields is not working in 64-bit Chimera but works correctly in 32-bit Chimera. Also as reported earlier a Mavericks graphics driver bug causes Chimera 1.8 to crash displaying any atoms or bonds. The crashing problem has been fixed in today's Chimera daily build (by disabling an advanced graphics feature automatically on Mac 10.9). So the only Mac Chimera that will work correctly on Mavericks is today's 32-bit daily build (or newer). Tom

Hello, I'm trying to fade a surface to 100 transparent with the following command transparency 100,s #2 frames 30; wait 30 and when the surface goes from 0% transparent to 1% transparent I see the following clipping at the top of the surface: What is causing this and how can I eliminate it? Thanks, Scott

Chimera crashes on Mac OS 10.9 Mavericks
by Tom Goddard 23 Oct '13

23 Oct '13

For those updating to the newly released Mac operating system Mavericks (10.9), we already have several reports that Chimera crashes showing any molecule due to a graphics driver bug in the new Mac operating system. I suggest not updating to Mavericks immediately if you want Chimera to continue to work. Only Apple can fix this bug. But we will disable the advanced graphics that leads to the crash in tonight's daily build. So if you already updated to Mavericks you can try the Chimera daily build (available about 16 hours after this post) instead of the Chimera 1.8 release. If you want the Chimera 1.8 release to work in Mavericks you'll need to disable DrawElementsInstanced in the Chimera debug graphics driver dialog. http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/debug/debug.html Disabling this graphics feature (which is what the daily build will do automatically) will cause rendering of large molecules to be slower when atoms are shown as spheres/balls or bonds are shown as cylinders, about 30 times slower. Still it should be as fast as the older Chimera 1.6 version where we did not use this advanced graphics feature at all. Tom

Chimera and Mac Mavericks
by Evan Kantrowitz 23 Oct '13

23 Oct '13

I just install Mavericks on my Mac. Chimera starts OK, but if you try to type into a field, like the PDB fetch field, entering key strokes is very hard.
