Dear Chimera-X users!

I am dealing with the visualisation of a complex dimer where each monomer is defined as a separate model like #1 and #2. For visualisation purposes I need to rotate the input construct by 180 degrees with the axis of rotation in the middle between the two monomers to avoid the shift of the complex in the x-plane at the end. That's what I have tried:

# turn on 180 deg during 10 sec

roll y 0.72 250 center #1,2 protein

wait 250

but the construct still shifted a bit towards one of the monomers. How could I do ii using the rotation axis, which would be in the center between them ?

Many thanks in advance

Enrico
