Hi Emilie, 
How to use the command is shown in the "view matrix" help: 
< [ http://rbvi.ucsf.edu/chimerax/docs/user/commands/view.html#matrix | http://rbvi.ucsf.edu/chimerax/docs/user/commands/view.html#matrix ] > 

There is no colon, you would want a command something like the following, all on one line (the Mail app may show it as broken into multiple lines but it should all be one line): 

view matrix camera -0.97114,-0.2031,0.12509,57.651,-0.030537,0.62598,0.77924,221.24,-0.23657,0.75293,-0.61412,-21.353 

I hope this helps, 
Elaine

Dear Elaine, 

Thanks for your answers, it really helps me to understand how to use ChimeraX. 

For the question 2 
I manage to get the camera matrix by using view matrix in the command. Then I moved my structure and tried to apply the camera matrix I had, but I did not suceed. 
I did view matrix :the number obtained in camera position 
Here is a picture of the log :

Please do you know what I did wrong? 

Thanks by advance for your help, 
Best regards, 

Emilie

Hi Emilie, 
(1) Cartoon thickness. You would use the "cartoon style" command to change the ribbon dimensions and shape. It can be done separately for helix, strand, and coil. For example: 

cartoon style coil thickness 1.0 

There are many options, see: 
< [ http://rbvi.ucsf.edu/chimerax/docs/user/commands/cartoon.html#style | http://rbvi.ucsf.edu/chimerax/docs/user/commands/cartoon.html#style ] > 

(2) Multiple images from different sessions with same orientation. 

(A) If all your different sessions were made with either the same starting structure (same PDB file) or structures that were already fit on each other when they were opened, you could get matrix from the view that you want and apply the matrix to all the others. You would use "view matrix" without arguments in the session that already has the view you want, to report the camera matrix in the Log. Then you would use "view matrix" specifying that camera matrix in your other sessions to put them into the same view. 

(B) If all your different sessions were made with different PDBs that weren't already fit on each other, then I believe the only way is to include a reference structure in each one, make sure the reference structure is in the position you want as in (A) above, and match the structure for the image onto the reference structure (e.g. with matchmaker or align), and then hide the reference structure. 

I hope this helps, 
Elaine

I have about 10 files of the same p53 structure (same PDB) with different groups of residues highlighted and now I would like to take pictures of them with the same display of the protein (same angle, rotation) in order to compare the 10 pictures together on a same figure. Is there a way to copy the angle/rotation of one p53 structure, and to apply it to another p53 structure?
