hi Tamas,
are all of your models aligned to your reference structure? if so,
you could just add your reference as a separate model in your multi-
model file - no need to add it as a chain to every model. Jmol has
decent tools to manipulate models. (there are several tools available
for aligning models, for example, DeepView.)
Indeed they are aligned. So u say that e.g. I can make jmol render model 0 as static, and all the others animated?
