Bee Visualization for WbLS

Prepare the data

cd scripts/
root -b -q loadClasses.C 'run.C("/path/to/ratfile.root", eventNo)'

This will create a new directory data/ under the scripts/ directory with the following structure:

data/
├── 0
│   ├── 0-Attenuation.json
│   ├── 0-Cerenkov.json
│   ├── 0-G4FastSimulationManagerProcess.json
│   └── 0-Transportation.json
├── 1
│   ├── 1-Attenuation.json
│   ├── 1-Cerenkov.json
│   ├── 1-G4FastSimulationManagerProcess.json
│   └── 1-Transportation.json
...

Any existing files there will be replaced by the new ones, so make sure that you intend to do that.

After you verify all files are produced correctly, move the whole data/ directory up one level so that the data directory is at the same level as js/ and scripts/. Backup any old data, if any, beforehand.

View the data

If you're using python2, do:

python -m SimpleHTTPServer

If you're using python3, do:

python -m http.server

Then open a web browser and go to http://localhost:8000/

Depending on how many events are under the data/ directory, you may want to change the MAX_EVENTS accordingly at the top of the file js/wbls.js. The event numbers must start from 0 and increase continuously.

Remote Access

The following uses Milind workstation (mvd) as the server as an example.

Login mvd with ssh forwarding of localhost:

ssh -L 8000:localhost:8000 mvd

where mvd is alias for host, which I've set up in my ~/.ssh/config file on local machine:

Host mvd
     ForwardAgent yes
     ForwardX11 yes
     ForwardX11Trusted yes
     HostKeyAlias mvd
     Hostname mvd
     PreferredAuthentications publickey
     ProxyCommand ssh -A [username]@physsh.phy.bnl.gov -W %h:%p
     ServerAliveInterval 60
     User [username]
