Hi,
Thanks for your interest in our 2013 3DNA JoVE article. As you noticed, this JoVE section is not complete (unfortunately). Moreover, Andrew Colasanti is no longer involved in the 3DNA project for many years. You may ask Dr. Wilma Olson directly to see if she has the original data files.
Even though I do not have the supplementary files for protocol 4 you requested, you could find an example of the list file by performing the following steps in the $X3DNA/examples/ensemble/md folder. Check the content of file pdb_list.dat.

x3dna_ensemble analyze -b bpfile.dat -p 'pdbdir/model_*.pdb' -o ensemble_example3.out

Best regards,
