Hi,

I am trying to make a movie form a set of morphed pdb files. Currently the individual files are loaded into the same object with increasing states, all pdb files contain the SHEET and HELIX record created by dssp.  The object is then displayed as a cartoon. When I loop over the states I noticed that Pymol only seems to take secondary structure information from the first pdb file into account. For instance I have a helix which is split into 2 during the morph, but only displayed as one helix during the animation, albeit a bit stretched. Loading the individual files produces the right sec. structure. Any idea how I can convince Pymol to update the cartoon representation with each frame?

Cheers,
