Hi Edward,
when I attempted to write out a PDB with the diffusion tensor representation
with structure.create_diff_tensor_pdb() I encountered the error given below
while the axes are being generated. The reason is that the sim_axes array is
empty. After commenting out the "res_num = generate_vector_residues(..)" line
in the "diffusion tensor" function, the PDB file is successfully written out,
but without the axes of course.
I could reproduce this with two different results files, that's why I guess
the error is not on my side ...
structure.create_diff_tensor_pdb(file='tensor.pdb')
