Hello, Thank you for your helpful replies. I apologize for my late response. So following the initial suggestion by David, I have an alignment of protein A with protein B, but with protein B hidden. This is in file prot_A_aligned.png. However, I am wanting the ribbons of this file to look like those in the image prot_A.png. This is the chimera view for the .pdb file of protein A before alignment with B using TM-align. That is, I want the parts of the protein which are not alpha-helices or beta-sheets to just be in the licorice form. Is this something I can do in chimera? Or is this something that would be integrated into the actual .pdb file which I would have to manually manipulate? I apologize if this is question has an obvious answer.

However, given the situation you have now, maybe: (1) in session 1, use "matrixget <file-pathname>" to save file with transformation of protein A. See: <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/matrixset.html> (2) in session 2, use "matrixset <file-pathname>" to apply the transformation from the file you saved in part 1, assuming protein A has the same model number as in session 1. However, that will probably ignore protein B, so you may need step 3. (3) in session 2, if protein A is model #0 and protein B is model #1, use command "matrixcopy #0 #1" See: <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/matrixcopy.html> I am not completely sure it will work since it depends on how you got the TM-align alignment in there, but it has at least a chance. Also you may need to adjust the command if you have different model numbers. I hope this helps, Elaine ----- Elaine C.

Dear Kenneth,
Maybe it be best to put both protein A and B in the same cartisen coordinate system by alignment such as matchmaker program, then save the PDB files. Then work on the problem from there on. This seems like a possible direction to try?
Sincerely, David

Hello,
I wish to generate two images. The first is of protein A which is in session 1. The second is of protein A aligned with protein B using TM-Align which is in session 2. I wish for the alignment of the second image to be in the same orientation as the first with respect to protein A. Is there a feature which lets me do the following:
1) Identify orientation of protein A in session 1 2) Copy that orientation 3) Apply that orientation to protein A in session 2 4) Have protein B in session 2 remain aligned to protein A despite the new orientation
