# hint: cmd.select("bb","id 3 in geom")
#
# displacement vector -> arrow
# for primitive cell atoms only... -> randomly put arrows in positive/negative phase
# -> seems to be working properly
# read in extra mode files (local mode vectors...)
# append or add to the table
# parse calculation output - gaussian 09/16 - molecules done

# vibration in supercell -> this_vib_supercell -> done
# clear up the vibration information when new structure is loaded -> done
# re-design the GUI layout, current design is too long in height -> adjusted
# generate movie -> done
# if no "convert" utility exists, then we could only save ".png" files
# we recommend to install the third party utilities to generate videos
# maybe it's better to just pop up a dialogue window saying that just use PyMOL's
