Chimera Settings
by Nuwan De Silva 24 Apr '19

24 Apr '19

Hi, Every time when when I open a file my background color, and presets, changes. I want to keep them same for every time. How can I set these things? For example, I wanted to have A) Presets —> Select Publication 1 B) Tools —> Structure —> Find H bonds C) Actions —> Atoms & Bonds —> Balls & Sticks Thank you, Nuwan

about select and label a residul with another different from the color of the whole model
by 张雷 13 Apr '19

13 Apr '19

Hi the experts of Chimera, Good noon! I had selected a residul and labeled it with the commands sel #0:500 rlabel #0:500. Then, the label can be displayed on the selected residul. How could I change the color of the label and display the label in a different color different from the color of the whole model? Thank a lot! Sincerely, Lei Zhang Peking University, Beijing, China

Hidden water molecules
by Michael Sharkey 11 Apr '19

11 Apr '19

Hi I'm trying to visualise water molecules associated with the crystal structure of an enzyme (specifically PDB ID: 1C1D). They're listed when I open the pdb as a text file using WordPad, but I can't for the life of me get them to appear on the screen when I try to visualise the structure in Chimera (v. 1.10.2). What am I missing? Thanks in advance Mike --

Constrainted fitting
by Christoph Wigge 22 Mar '19

22 Mar '19

Dear all, I would like to fit two protein monomers that form a dimer into an em density map. I know from previous mutagenesis studies that the binding takes place with two tryptophan residues and the counterpart binding pocket. How can I set this interaction as fixed so that chimera fits the rest of the molecule according to the density map without continuously changing this part of the essential protein protein interaction? I would like to fit that interaction manually and then exclude it from the automatic procedure. Thank you very much in advance. Bests Christoph Wigge

How to color density maps using markers?
by Ahmad Khalifa 05 Feb '19

05 Feb '19

I know I can use volume tracer to place markers in the density. There was a tutorial explaining the use of these markers to color certain areas of my density map, however I lost track of it. Best regards.

Combine atom-spec non-alphanumeric no-nunderscore character error
by Ahmad Khalifa 01 Feb '19

01 Feb '19

I'm trying to combine a few chains from different models. I'm using: combine #1:.k,.e #2:.k,.e. I'm getting the above error, and I'm not sure why my selection isn't working! Regards.

question
by Craig Scoville 31 Jan '19

31 Jan '19

Dear Staff -- I am interested in using Chimera but have a question regarding its use. I am interested in looking at the shape of small polypeptides --usually ranging from 5-20 amino acids -- does this program allow me to input amino acid sequences and then look at confirmational shapes? make substitutions and then compare confirmational shapes? Does the proprietary nature of my work prohibit me from using Chimera? Sincerely, Dr Scoville

rmsd graph
by SEFA ÇELİK 31 Jan '19

31 Jan '19

Dear Dr. I am using Chimera software(windows platform). I tried to get rmsd graph(using the plotting in the MD Movie trajectory viewer). And I got the result. But, graph's x-axis "frame" and y-axis "rmsd" value. I want the x axis to be the "time". Briefly, I want to see how the value of rmsd changes with time. *I added files to the e-mail. Can you explain what "1001 frames" mean? And how do I convert "1001 frames" to time. I want to see the RMSD change by time.* Can you help with this? Could you explain in detail? Best regard Assoc Prof. Dr. Sefa Celik

Morph conformation - side chains
by arrafzaher＠campus.technion.ac.il 28 Jan '19

28 Jan '19

Hi, I noticed Morph conformation only compares backbone Is it possible to compare side chains conformation change Lets say enzyme vs. phosphorylated same enzyme on a tyrosine residue (TPO) Thanks Zaher
