Flask Dataviewer Application

Provides a Flask web service to extract the images from nexus files. It is based on dials to generate images (dials v2.1.3+). Need to use dials.python to get the correct environment.

gunicorn_runner allows the app to run on the command line but with worker threads.

Assumes you already have dials installed - pip does not install this for you
