Buenas tardes, Estoy intentando descargar vuestro programa y me es imposible porque cuando acepto vuestras condiciones me salta un mensaje que dice: “Gracias por considerar la quimera UCSF. Por favor, háganos saber qué parte del acuerdo de licencia UCSF Quimera que encontró inaceptable.” No entiendo porqué sucede esto si yo estoy aceptando las condiciones y necesito urgentemente el programa. Por favor, necesito su ayuda. Gracias Enviado desde Correo para Windows 10

Re: [Chimera-users] transposing a pdb structure ("copy & paste")

Hello Elaine. Has there been any development of this problem since the 2007 post? I’m trying to duplicate a small group in a large molecule and use the copy to substitute it an existing group of very similar size in the same molecule.

Contact_area Arguments
by Kevin Wang 06 Dec '19

06 Dec '19

Hi, I am using python to calculate contact area between 2 chains. My code is as follows p1, p2 = [s.surface_piece for s in openModels.list(modelTypes=[MSMSModel])] y = measure.contact_area(p1, p2, 2.5) However, this returns the error: TypeError: contact_area() takes at least 4 arguments (3 given) This is the function for contact_area def contact_area(p1, p2, d, color = None, offset = None, slab = None, smooth = False, optimize = True): What is the 4th required argument? Best, Kevin

pseudobond problem while writing mol2 format
by Palani, Kirubakaran 06 Dec '19

06 Dec '19

Hi All, I have a PDB file and want to convert the PDB to MOL2 format. The PDB has missing residues which is not a problem but when I write to MOL2 format it assigns the pseudobond and I really no need of it. I tried to solve it by checking the thread but I am not getting a clear solution for my problem. Last, I am doing this by using the script as I have >1000 PDBs to process the same way so the command line would be preferred. PS: I send you the molecule in PDB format as an example case.

Opening Amira segmentations
by Tom Goddard 06 Dec '19

06 Dec '19

Unfortunately Chimera does not handle Amira segmentation files. Maybe we can add that to ChimeraX or next generation program. What kind of segmentations do you have? Are they surfaces? Or are the per-voxel index maps? Tom > On Dec 5, 2019, at 12:02 PM, Guo, Wangbiao <wangbiao.guo(a)yale.edu> wrote: > > Thank you, Tom.

That line tells ChimeraX the size of the 3D image data in the file. I suspect it means your Amira file does not contain 3D image data (instead it might have segmentation surfaces or some other Amira objects). The Chimera Amira reader only handles 3d image data. >> >> Tom >> >> >>> On Dec 5, 2019, at 11:36 AM, Guo, Wangbiao <wangbiao.guo(a)yale.edu> wrote: >>> >>> >>> >>> >>> <Screen Shot 2019-12-05 at 2.32.48 PM.png> >>> >>> >>> >>> >>> >>> >>> >>> >>> Hi: >>> When I open my Amira label file by Chimera, I always come out with an error: cannot find “bounding box” line, can u help me to figure out? >>> _______________________________________________ >>> Chimera-users mailing list: Chimera-users(a)cgl.ucsf.edu >>> Manage subscription: https://nam05.safelinks.protection.outlook.com/?url=http%3A%2F%2Fplato.cgl.… <https://nam05.safelinks.protection.outlook.com/?url=http%3A%2F%2Fplato.cgl.…>

Video about masking
by Krishan Pandey 05 Dec '19

05 Dec '19

Hi I am kind of new to Chimera and was wondering if there is a video tutorial about creating a mask in Chimera. I intend to use the mask for local resolution or multi body refinement. To experienced users this may be a novice question. I tried to search online but could find any. When I use volume eraser to delete part of EM map, it does not do anything, nothing is deleted. I am using Chimera 1.13.1 (build 41965). Any help is appreciated. Thank you Krishan Pandey

Fitting ligands/substrates to protein structure
by Jason Jeffrey Rodencal 05 Dec '19

05 Dec '19

Hello chimera users! I've been browsing the various tutorials for chimera and I've seen a lot of amazing models of proteins bound to DNA, ligands, etc. I have a pdb file for my protein of interest and its substrate, and I have the active site of the protein. I was wondering if there's any way of predicting how the substrate fits into the catalytic cleft. Is there some easy code or application that can do this in chimera or is this a far more challenging task than I appreciate? Thank you! Jason Rodencal Dixon Lab Stanford University
