Asymmetric processing of visual motion for simultaneous object and background responses

• tutorial-src phenomenological model source code and explanatory text
• emd-src physiologically based EMD model

Supplemental Code - Quick start

You can either chose to run all code on your physical machine (please refer to the README documents in the specific folder) or you can run the code in a predefined virtual machine, where it's known to work.

For the second option please install the following programs first:

• Virtualbox
• vagrant

Then access this folder with your operating systems terminal (command line) and type:

vagrant up

Wait for the above to finish, which can take a long time (about 2GB of files need to be downloaded).

Lauching the IPython notebook

After vagrant up finishes, your newly installed virtual machine is running the IPython Notebook server in which you can interactively run and edit the code. Do by visiting the following URL in your browser: http://localhost:8888/.

Building PDF versions of the documentation

vagrant ssh
cd /vagrant/tutorial-src
make pdf-standalone
exit

This generates the supplemental experimental procedures text and figures for the phenomenological model. You'll find them in the tutorial-src folder when the program is finished.

And:

vagrant ssh
cd /vagrant/emd-src
python calculate_figure_data.py
python save_plots_as_pdf.py
exit

This generates the all figures for the EMD model. It will take a very long time (on a single core >40 hours) when run in the virtual machine. You'll find the generated figures in the emd-src folder after the program is finished. It is recommended to run the EMD code on a multi-processor machine natively (refer to the README document in the emd-src folder).
