control the movie play speed

Hi, I am using chimera to record the movie of a MD trajectory into a mpeg format vedio. How can I set the interval between neighboring snapshots? It seems the playback option in the MD movie dialog can't do that. Thanks! Mingfeng

Background transparency
by Alon Ben-David 26 Jan '06

26 Jan '06

Hi My name is Alon and I am a graduate student at the Technion, Israel institute of technology. My question is how can I create a transparent background to pictures I am generating with Chimera. I read at the site that not all hardware's permit a transparent background, but I don't know how can I check if my hardware do. Thank you in advance and best regards Alon

command line for showing and hiding (same as clicking shown checkbox in model panel?) and volume viewer options in a cmd file?
by sabuj pattanayek 26 Jan '06

26 Jan '06

Hi, I'm trying to make a movie using a cmd file. I want to show and hide (same as clicking the checkbox for shown in the model panel) models from the cmd file since the system becomes too slow to do it manually while the movie is recording and timing frames is even more difficult. I also want to decrease and increase the isosurface threshold level in the volume viewer from the cmd file. Is it possible to do these without using the mouse while a movie is recording? Thanks, Sabuj Pattanayek

So, yes, it's the driver's fault.

Question
by Jin Chai 23 Jan '06

23 Jan '06

Dear Sr/Ms, I wonder if chimera molecular modeling system can be used beyond molecular level. we try to use chimera to create 3D images on mouse colon crossection images(dataset) we collected from SKYSCAN Micro-CT 1076 . Do you think it will work? Looking forward to your opinion. Thanks in advance, Jin --------------------------------- Yahoo! Photos Showcase holiday pictures in hardcover Photo Books.

Saving a multiscale model in VRML
by R. Andrew Byrd 17 Jan '06

17 Jan '06

Greetings, Our publications group has a new device that they call a 3D printer. It can make solid models from a data file. They have made models from pdb files as ball-and-stick, and I saw one surface rendered model. They tell me that the input is in VRML. So, I am wondering how to make a VRML file from a session in Chimera where Multiscale Model tool is used to make a surface rendering of a complex model...several proteins. My model is not as complex as the virus examples for multiscale models, but the ability to make different resolution surfaces is a powerful aid. I would like to try and 'print' a 3D model of this surface rendered complex. Any help in out to output the VRML file for the printer?> Thanks Andy -- R.

Slow framerates (on a nice laptop)
by Charlie Moad 17 Jan '06

17 Jan '06

So in general I get really good performance with chimera, but for some reason I get really bad frame rates with more recent releases on windows with my laptop. It has a really nice card, GeForce 6200TC Go. It is even on a pcix16 bus. I am guessing that since it is a newer chipset, chimera is using shaders of some kind? The molecule looks visually smoother/better than when in linux. In any case, it seems something is getting enabled that really bogs it down, and I would like to be able to disable it. Sony Vaio FS500 Chimera 1.2184 Thanks, Charlie
