Hi Nara, In Chimera you can hide (undisplay) the atoms, ribbon, or whatever is shown, or you can delete those parts you are sure you don't want. In your session, it looks like you already selected the part you don't want, chain A. To hide those ribbons, choose from the menu Actions... Ribbon... hide or, to delete that part if you never want to see it again, choose Actions... Atoms/Bonds... delete The Actions menu applies to your selection, which is chain A. If you hide it, it will still be selected, until you clear the selection or select something else. If nothing is selected, the Actions will apply to everything, so be careful not to choose "delete" unless you are sure what you want to delete is selected! After you delete the selection, nothing will be selected. You could also do the same things using the commands "~ribbon sel" and "delete sel" - I hope this helps, Elaine ----- Elaine C.

Hi,

I need help. I received the modeling structures of my query (black) and the best representative 1qopB (magenta) through MODWEB, and used Chimera to visualize them (please see attached file). However, the magenta structure also contains 1qopA, in which I only want the 1qopB and don't want the 1qopA. I read through tutorials but cannot find a way to get rid of the chain A of the 1qop.

Hence, could you please direct me of how to cut out chain A of 1qop in this attached file? Thank you very much.

Sincerely yours, Nara<TrpB.1qopB.refDEFGHIaJ.ver2.chimerax.py>__________________________ _____________________ Chimera-users mailing list Chimera-users@cgl.ucsf.edu http://www.cgl.ucsf.edu/mailman/listinfo/chimera-users
