Hi, I are trying to use Chimera to produce duplicates of one fibrinogen, rotate and move them, and concatenate together in a certain way. The fibrinogen looks like this (http://dl.dropbox.com/u/3757507/chimera1.png). I want to duplicate the model, and connect them in a chain (http://dl.dropbox.com/u/3757507/chimera2.png). The second image shows only two instances, but there will be more. Currently I do it by hand, including rotating and aligning them in correct z positions. But it take a lot of time to do it because the duplicates generated by using Tools/Higher-order structure/Unit Cell are not in the same plane. I have to look back and forth in different directions to make sure them are aligned. So I are wondering is there any way to automate this process, such as apply the previous transformation to a new duplicate? Thanks, Joe
