Structural representation of the individual frame order motional components.
root: The file root for the PDB files created. Each motional component will be represented by a different PDB file appended with `_mode1.pdb', `_mode2.pdb', `_mode3.pdb', etc.
dir: The directory where the files are to be saved.
atom_id: The atom identification string to allow the representation to be applied to a subset of all atoms.
model: Only one model from an analysed ensemble of structures can be used for the representation, as the decomposition PDB files consist of one model per state.
total: The total number of structures to distribute along the motional modes. This overrides the fixed angle value.
reverse: Set this to reverse the ordering of the models distributed along the motional mode.
mirror: Set this to have the models distributed along the motional mode shift from the negative angle to positive angle, and then return to the negative angle.
force: A flag which, if set to True, will overwrite the any pre-existing file.
An alternative way to visualise the frame order motions is to decompose the motions and visualise each mode separately. This user function will create a uniform distribution of structures shifted from the original position and rotated around the eigenvector for that motional mode. Each distribution will be output to a PDB file appended with `_modeX.pdb', where X are the discrete motional modes ordered from largest to smallest. The curved line of positions will extend over the full distribution of structures.
