Data View

Using Dash/plotly, this project is a web-interface for browsing a directory tree and viewing hdf5 data.

Installation

Install with python setup.py develop or pip install -e /path/to/dataview

The code is written in Python3 and relies on the following pacakges: h5py,numpy,dash,dash-core-components, and dash-html-components. If your files are accessed via Samba, you also need pysmb

To run the app with the test server...

python run.py

I followed this guide to set up the application on an NGINX web server.

$ cat /etc/nginx/sites-available/dataview
server {
        listen 8082;
        server_name server.physik.unibas.ch;
        ssl on;
        ssl_certificate /path/to/cert.crt;
        ssl_certificate_key /path/to/privatekey.key;
        location / {
                include proxy_params;
                proxy_pass http://unix:/srv/dataview/dataview.sock;
        }
}

You need a symbolic link to that file in sites-enabled

sudo ln -s /etc/nginx/sites-available/dataview /etc/nginx/sites-enabled

And this is the systemd service file:

$ cat /etc/systemd/system/dataview_gunicorn.service
[Unit]
