Chimera morphing is limited to fairly similar models. The first thing it tries to do is identify the equivalent atoms from both models. When there are unequal number of chains in the models, it is not smart enough to figure out which is the extra chain. A workaround might be to create a copy of 3VBS, delete the chain from 3BVS, and morph between the copy and 3VBU. The shortened copy of 3VBS must be an open model, but it does not need to be displayed. Conrad On 5/12/2013 2:24 AM, 吕柯 wrote:

Dear Sir./Madam,

I am a graduate student in Chinese Academy of Sciences.

I have two PDB files: one for virus(4 chains, PDB:3VBS), the other for empty particle(3 chains, PDB:3VBU).

I would like to use Morph Conformations to make movie for that. However, it turns out "Can not interpolate models: models have different number of chains".

Could you please show me what should I do next?

Thanks a lot.

Yours, Lyu Ke
