[Chimera-users] chimera help - calmodulin

Hi, I am a student trying to do a project on the protein calmodulin. I have just started using chimera and have gone though your tutorials and understood everything as it is very clear but i don't know how i would select the protein calmodulin and put it in the chimera display to make my images. I realise this is probably a simple step but this is all new to me and i would much appreciate your help. Thank you Annabel Roach
