The visualisation of eigenmodes is done via structure rendering.
<pymol.com> eigenRendering.py <rendering-file-name> \ <structure_file-name> <storeall_name>
where storeall is the output file of dispersionDeb.py and rendering-file has the additional information of which mode has to be visualised :
Rendering_Radii=[0.5,0.6,0.7 ] colors=[ [0.0,0.0,1.0], [1.0,0.0,0.0], [0.0,0.5,0.0] ] nneig=[1,1,1] NPscan=48 NPvector=41 fampli= 2.0
where NPscan specifies ( NPscan starts from 0)
and NPvector is the eigenvector number ( NPvector goes from 0 up
to is).
