[Chimera-users] split

Hi All, I understand the use of split as outlined in the tutorial describing how to find the contact region between two chains. file:///Applications/Bioinformatics/Chimera.app/Contents/Resources/share/chimera/helpdir/UsersGuide/frametut.html I don’t know the proper syntax for models with more than two chains, e. g. A, B, C, D, and E where you might like to split the model either as: A, B, D, and E in one group C in the other or A, B, and D in one group and C and E in the other. I would be grateful for a recommendation for the correct syntax to use in the argument list to form two groups to identify the contact surface after further processing (in the same manner as the tutorial). Thanks, -John
