   -h | --help
     Display this help
   -d | --download
     Download the AliESDs.root file using the provided URL
   -u | --url URL
     Provide the URL to uniquely identify a AliESDs.root dataset.
     This should be in the format provided by http://opendata.cern.ch.
     See example below.
218
   -m | --maxparticles VALUE
219 220
     Get only events for which its number of particles does not
     exceed VALUE.
221
   --minparticles VALUE
222 223
     Get only events for which its number of particles is greater than
     or equal to VALUE.
224
   -n | --numberofevents VALUE
225
     Set number of events to be animated inside chosen ESD file (defaults to 10)
226 227
   --minavgpz VALUE
     Get only events for which its absolute value of average momentum in
228 229
     the z direction is greater than or equal to VALUE, in GeV/c. Useful
     for animating events with 'boosts' of particles to the same side.
230 231
   --minavgpt VALUE
     Get only events for which its average transversal momentum is
232 233
     greater than or equal to VALUE, in GeV/c. Useful for animating
     events with 'boosts' of particles on the xy plane.
234 235 236
   -t | --duration VALUE
     Set the animation duration in seconds.
   -r | --resolution VALUE
237 238
     Set the animation resolution percentage, where
     VALUE must be an integer from 1 to 100.
239 240
   --fps VALUE
     Set number of frames per second in animation.
241 242 243
   --transparency VALUE
     Set detector transparency as a number greater than zero,
     where zero is full transparency and 1 is standard transparency
244 245
   -c | --cameras VALUE
     Which cameras to use for the animation, where VALUE
246
     is a comma-separated list (without spaces)
247
     Options: Barrel,Side,Forward,Overview (defaults to Overview)
248 249 250 251
   --mosaic
     Make animations in all four available cameras and combine them into
     a single 2x2 clip containing all perspectives, totalizing five generated
     .mp4 videos.
252
   --picpct VALUE
253 254
     Percentage of animation to take HD picture, saved along with the clip,
     where VALUE must be an integer
255 256 257
   --bgshade VALUE
     Set background shade of black to VALUE, where 0 is totally black
     and 1 is totally white
258
   -a | --sample
259
     Creates a sample Blender animation of Event 2 from URL
260 261
     http://opendata.cern.ch/record/1102/files/assets/alice/2010/LHC10h/000139\
038/ESD/0001/AliESDs.root
262
   --its
263
     Removes ITS detector from animation
264 265
   --detailedtpc
     Includes more detailed version of TPC in animation
266
   --tpc
267
     Removes TPC detector from animation
268
   --trd
269
     Removes TRD detector from animation
270
   --emcal
271
     Removes EMCal detector from animation
272 273
   --blendersave
     Saves Blender file along with animation clip
274 275 276
