Hi:

First up, thank you and your team for all your efforts in creating and maintaining Chimera and ChimeraX. They are an awesome tool/package!

It would be very helpful if you could please assist me with the two questions below.

1) I have a PDB downloaded from Alphafold. I would like to ‘drag out’ or reposition regions in order to enable their better visualization for a figure that I need for a grant. How can I select and reposition specific regions of a protein structure in ChimeraX?

2) The protein of my interest is a homodimer. I would like to open two copies of the relevant PDB file and manipulate them as two separate proteins. I have made a duplicate and relabeled the PDB file. However, when I open it ChimeraX along with the original, the two files seem linked, and I am unable to work on them separately. Is there a way to open two copies of the same PDB file to ‘recreate’ a homodimer?

Thank you,

Best,

Mahesh
