#Datacard Viewer

Datacard Viewer is a Graphical User Interface tool for exploration of Higgs measurements in datacards.

##How to use it

The tool works like this:

• Install Flask server on network.
• Type server's address in a browser.
• Upload datacards and their ROOT files you want view.
• View them.

##Installation

###General Requirements

Server side (libraries):

• Python 2.6 or higher.
• Flask 0.11 or higher.

Client side (browser):

• Safari, Chrome, Firefox, Opera.
• IE8, IE9 or newer.

###Flask

Flask can be installed in two different ways:

1. using Flask Local and System-Wide installation guides.

2. or building and installing System-Wide Flask from the source:

   $ cd libs/flask-0.11
   $ python setup.py build
   $ sudo python setup.py install

To launch your web server go back to the DatacardViewer folder and type:

$ python run.py

If it doesn't work, go to run.py and configure it manually.
