[Chimera-users] .crd file not opening

Greetings, hope you are doing well. I want your guidance on how can I open a .crd file on UCSF Chimera. I am working on a protein and its mutants and performed their docking via Swiss Dock, it gave results in form of .crd file that I cannot open. My supervisor also has no idea how to open it, so please help me in this regard, I need to open it to work further on my research. Waiting for your kind response please.
