compressed versus gzipped Re: Read compressed PDB files -question, suggestion
by Moo Cow 12 Dec '06

12 Dec '06

A thousand pardons. You are right. I phrased the question wrongly. Chimera does open gzip'd files ( xx.gz). It does not open compress'd files (xx.Z). > You can also open gzipped files with Chimera's "open" command or as > an argument as you start Chimera. [...] > > You can use the Chimera File / Open... dialog to directly open a gzip > > PDB file. This was added to Chimera about one year ago. It does not work Why, you may ask, would anyone use compress these days ? If you mirror or rsync the protein data bank, they are still distributing files that have been squashed with compress and have a ".Z" extension. gunzip will happily eat and uncompress these files. I do not know how chimera handles compressed files. If it reads from a pipe, it might be nice to persuade it to feed .Z files to gunzip. I think it might be more difficult if chimera uses the python/zlib interface. Many thanks -- Search for products and services at: http://search.mail.com

SDF format
by Randy Heiland 12 Dec '06

12 Dec '06

Just wanted to ask about Chimera's support for reading in SDF formatted files, e.g. from PubChem. It seems not to be one of the supported formats. Obviously we can use a converter to get pdb format, but thought I'd ask the experts. Thanks, Randy

saving with angles
by Gabor Papai 12 Dec '06

12 Dec '06

Dear everybody, Is there a way in Chimera to save density maps when I rotate them with the modified angles? In practice, I use the 'fit map in map' to align two maps in respect to each other and I would like to save them for further analysis with different softwares. Therefore I would like to conserve their position (shift and rotation).

Dear all, I have a simple question: does Delphi controller works under unix only or it is possible to work with it under Linux and/or Windows XP?

Read compressed PDB files -question, suggestion
by Moo Cow 08 Dec '06

08 Dec '06

We store the PDB locally, but compressed. Can one persuade chimera to read coordinates from a pipe ? Maybe this could be done at the python level. It might also not be too hard to use the python binding to the zlib library, but I would not know how to do this. I imagine the interest (or not) would not be limited to reading PDB files. many thanks for any suggestions. -- Search for products and services at: http://search.mail.com

Apply the symmetry to the fitted models in map
by Hong-Wei Wang 06 Dec '06

06 Dec '06

Hi, Tom I remember you were showing docking a model into map with high symmetry (you showed the actomyosin filament example). I am wondering how you generate the symmetry in the docking and if the symmetry information is necessary for the correct fitting. Thanks a lot!

volume viewer issue
by Matthew Shawkey 06 Dec '06

06 Dec '06

Hi, I am using chimera to visualize a stack of EM serial sections. I can load them into Chimera (as MRC file), but when I try to view the stack in the volume viewer w the "solids" option all I see is a white square.. w the mesh and surface options the stack shows up as a grainy image on which it's difficult to see any depth.. any suggestions? THanks, Matt

Uploading several trajectories for MDmovie
by Anna Feldman-Salit 04 Dec '06

04 Dec '06

Dear all, I would like to know if there is any possibility to sequentially upload several trajectories with MDmovie option (or command line) and then to visualize them with "no stop" in between. These trajectories were generated by AMBER with "restart" input files. Such an option happens to be in VMD, but it's more convenient for me to work with Chimera (I have Chimera1.2304). Thanks a lot in advance, Anna
