MD simulation movie in chimeraX
by Shivam Gupta 09 Nov '22

09 Nov '22

Hello Support Team, I am a commercial license user of chimeraX. I have .trr and .tpr files from the Gromacs MD simulation. I am not getting any option to create an MD movie. I know how to do it in chimera but couldn't find a similar GUI/option in chimeraX. Literature/tutorial of chimeraX didn't help me much. Please help me out by guiding me to generate MD movies. Please reply to this email inline. I am Looking forward to hearing from you.

Finding disulphide bonds
by Prathvi Singh 08 Nov '22

08 Nov '22

Hi Elaine, I have found out a way to select the disulphide bonded CYS residues in UCSF chimera using the command: *select disulphide*. However, is there a way to count the number of disulphide bridges in a protein and save in a variable? -- Prathvi Singh, Research Fellow, Department of Biological Sciences & Bioengineering, Indian Institute of Technology, Kanpur-208016

Question regarding 2dlabels in Chimera
by leonard.maurer＠uni-bonn.de 07 Nov '22

07 Nov '22

Hi, I am using Chimera for several years now and I really enjoy it, but there is one issue I could not solve until now: Is it possible to have subscript/superscript for the 2D labels? For example something like "subunit A\_{1}" and "subunit A\^{1}" that I can type either in the 2d labels GUI text part or with the 2dlabels command, which gives me the raised and lowered versions of the "1"? I am confident that this feature might be already implemented given Chimera's impressive amount of tools, but I was not able to find it in the documentation so far. Thanks in advance! Best regards, Leonard

Running the Modify Structure tool using command line in UCSF Chimera
by Prathvi Singh 03 Nov '22

03 Nov '22

Hi Elaine, Is there a way to run the *Modify Structure *tool in UCSF Chimera using command line? I want to substitute a S-atom with O-atom in more than 100 structures and doing it for each structure using the GUI looks very time consuming. Please help. -- Prathvi Singh, Research Fellow, Department of Biological Sciences & Bioengineering, Indian Institute of Technology, Kanpur-208016

Jagged edges in chimera X
by Prathvi Singh 03 Nov '22

03 Nov '22

Hello Elaine, Is there a way to smoothen the jagged edges seen around ribbons and sheets in ChimeraX? The jagged edges can be removed in UCSF chimera by setting the *subdivision *value to 20 and enabling multisampling but I do not see these features in chimeraX. -- Prathvi Singh, Research Fellow, Department of Biological Sciences & Bioengineering, Indian Institute of Technology, Kanpur-208016

Doubt regarding Copyright for the use of UCSF Chimera free software in research paper
by aiswarya tressa chacko 03 Nov '22

03 Nov '22

Sir/Madam, I am a post graduate student who is working on a research article which involves molecular docking and analysis. I am using the free software of UCSF Chimera (version 1.16) for obtaining results and analysing them. I am wondering whether using these results and images that I acquired from Chimera in my research study, will subject me to Copyright Issues. Kindly address my doubt as soon as possible.

Hi all, I was wondering how I could hide the xyz indicator in the center of window when I was viewing the X-ray density from mtz file? It only appears in crystal unit view mode but disappears in EM projection side view. Best, Xiang

How to invert a map values in UCSF Chimera
by Junha Song BA 31 Oct '22

31 Oct '22

Dear RBVI, I am currently looking into the ways to invert a map in UCSF Chimera so that I can flip the histogram of a map, but I cannot find a volume operation command that does the job. What command in UCSF Chimera allows creating a map with inverted map values? I thought it was vop but I cannot find a parameter that allows assigning negative value operation that would invert the map in UCSF Chimera command line documentation. Best, Junha Song.
