[Chimera-users] queries on making image

Hello chimera users, 1) I hve to show two molecules in the same figure side by side. When i am displaying, i have a problem that both molecules are not coming at same plane. Is there any option to adjust this. 2) I labelled both these molecules. The labels are coming fine in the screen. But when i create an image (i save it as tif file), some labels are getting hided below my molecular surface. Which option i should use to rectify that. 3) How one can add text on the screen/near a particular spot on the molecule ? 4) Someone kindly Suggest me on best settings (i mean values) of the resolution based on your experience of making figures using chimera or which you normally use. Thanks in advance, Bala
