missing bonds when visualizing in Chimera
by Aditi Laddha 01 Jun '23

01 Jun '23

Hello Elaine, I am facing some difficulties visualizing my structure in Chimera; whenever I open the .pdb file containing the sucrose molecule, the bond between glucose and fructose is missing (glycosidic bond). But all bonds are visible when I open the same file in other programs. I want to know about its hydrogen bond interaction with my protein and visualize them in Chimera. Please help me with this issue. -- Regards, Aditi Laddha PhD Scholar Indian Institute of Technology, Kanpur, Uttar Pradesh 208016

Re: permission denied (Chimera file saving)

Hello Dr. Sarkar, For questions about Chimera, please use the chimera-users(a)cgl.ucsf.edu address CC'd here. The problem is most likely that you are trying to save the file in a location (folder) where you do not have permission to write files. You need to choose a location on your computer in which you have permission to write files. I hope this helps, Elaine ----- Elaine C.

question regarding relative rotation
by Jannick Cornelius Snel-Prentø 21 May '23

21 May '23

Dear Chimera team, I would like to rotate a protein chain with respect to an axis that I define, but I cannot seem to find any way to do that. I have defined the axis, but the turn command will not allow me to use this as the center of rotation. I have also tried constrained motion, but this does not seem to have the parameters needed to do this. Is there a command or a menu that permits rotating a chain or structure around an axis you define yourself? Kr, Jannick

3D_printing

Dear Chimera Team, first of all, I would like to thank you for providing a sotfware solution to molecular visualization and by the way 3D- printing. I send you this message concerning the UCSF Chimera X version. We usually are preparing our 3D-printing files from data collected from the pdb and to ensure the rigidity of the system, we thick the ribbon size and also add some H-bonds (mainly for helices). However, we are not able to find the way to do it in this version. In the previous version (1.17), the command line was : Tools-depiction-ribbon style editor Could you explain us the new procedure to make this ? We also noticed that the opportunity to save the file in a stl extension was not allowed in the 1.17 version. This option is running in the X version. Thank you very much for your reply Best regards. fhporee François-Hugues Porée Professeur de Chimie Thérapeutique Institut des Sciences Chimiques de Rennes UMR CNRS 6226 Faculté de Pharmacie - Université de Rennes 2 Avenue du Pr Léon Bernard F-35043 Rennes France Tel.02 23 23 41 87

UCSF Chimera Molecular Dynamics: CPU vs GPU
by Alan Carbajo 07 May '23

07 May '23

Good morning, I'm running a molecular dynamics simulation in Chimera, and it seems that the program is only using my cpu for the calculations. Why is this? Is it possible to switch it to use my GPU? Thank you, Alan

Web site downtime
by Eric Pettersen 04 May '23

04 May '23

Hi all, Due to a scheduled power outage at UCSF followed by server upgrades, the Chimera website and web services will be unavailable from Tuesday May 16 through most of Wednesday May 17. This upgrade will remove the Opal web services used by older versions of Chimera. Therefore, to continue using the Chimera tools running BLAST protein, Modeller comparative and loop modeling, and multiple sequence alignment with Clustal Omega and MUSCLE web services, you will need to upgrade to Chimera 1.17 (Mac) and 1.17.1 (Windows/Linux). Please pardon any inconvenience. --Eric Eric Pettersen UCSF Computer Graphics Lab
