roygbiv (Roy G. Brain Image Viewer) is an interactive browser-based visualization of cortical surfaces.

Instructions for running demos are below. To run demos locally, install the flask Python package.

###To set up the main demo locally:

1. Run python get_data.py demo. This will download sample data files.
2. Run server.py to launch a light-weight web server
3. Browse to http://127.0.0.1:5000/

###To set up the two hemis demo locally:

1. Install vtk
2. Install mindboggle (pip install git+https://github.com/binarybottle/mindboggle.git)
3. Run python get_data.py fsaverage (or replace `fsaverage with your desired freesurfer subject)
4. Run python server.py to launch a light-weight web server
5. Browse to http://127.0.0.1:5000/fsaverage/desikan/pial/two_hemis.html

You can change parameters above and change the corresponding URL: * Use your subject ID instead of fsaverage, if you have your own data. * Use --atlas destrieux to use a smaller parcellation. * Use --surface inflated to view an inflated surface.

###To deploy your files remotely

1. Create the data (see above)
2. Upload all files to your remote web server (html, json, css, data)
3. Browse to http://your_web_server/your_roygbiv_directory/

Note:

• If you want your downloaded or generated data stored at specific location, please define the ROYGBIV_PATH environment variable.
