A short tutorial.

• phantom2: divertor
• phantom: outboard midplane

import view

Explore with a slider:

view.slide_phantom(1150625010) # can take up to 30 seconds

• Click on the Sub 20 option (and wait for a while) to do background subtraction
• Click the Recolor button to set the min/max colors to the min/max values of the currently displayed image
• Use the slider to move around the video
• Use the > and < buttons to move one frame forward/backward
• Click play to play 100 frames

Just play the whole thing at a good speed:

view.animate_phantom(1150625010, sub=20, interval=10, skip=1)

• All named arguments in this tutorial are defaults and can be omitted
• sub=0 gets the original video
• skip=N will display every Nth frame
• interval=20 and greater will play the video more slowly

import acquire
time = acquire.gpi_series(shot, 'phantom2', 'time')
frames = acquire.video(shot, camera='phantom2', sub=20, cache=False)

• cache=True saves a numpy object of the video to the cache directory

from phantom_viewer.fl import reconstruct
reconstruct.write_nnls_reconstruction(1150625010)

Takes about an hour.

from phantom_viewer.fl import view
view.slide_reconstruction(1150625010)

Make sure you run the code on a Fedora machine at the PSFC, the Red Hat ones have a different Python installation that has problems.

cd /home/sballinger/Desktop/phantom_viewer
source venv/bin/activate

In the directory with your scripts, do

ln -s /home/sballinger/Desktop/phantom_viewer phantom_viewer

then import all components in your script like this:

from phantom_viewer import blah

git clone https://github.com/sballin/phantom_viewer
cd phantom_viewer

Write scripts here or run the above commands from the console. If it complains about missing packages, do pip install --user [package name].
