Use your local browser to visualize ROOT files from Raad2

Starting from the version 6.26 of ROOT, there is a possibility to visualise ROOT files from a web Browser, hence improving the user experience.
No Web Browser are available on Raad2, but this feature is still usable through a Port Forwarding technic as described below.

On Windows

• Copy rootssh script from here: P:\Office of Research\Research Computing\RC\ROOT\rootssh and past it anywhere on your PC
• Open MobaXterm and click on "Start local terminal"

• In this terminal, issue the following command:

./Path/To/rootssh username@raad2.qatar.tamu.edu "module load root/6.28.06; root --web -e 'new TBrowser'"

• ("/Path/To/rootssh" is the folder on your local machine where you copied the rootssh script)
• That's it.
• That should normally open a new web page in Firefox, Edge or Google Chrome, from which you can navigate to your root file:

• To specify which browser to use, just add : --browser <name of the executable of the chosen browser>
• For instance, for Microsoft Edge, (let's assume you placed rootssh file on your PC in "This PC/Documents"), the command becomes:

./MyDocuments/rootssh --browser msedge.exe username@raad2.qatar.tamu.edu "module load root/6.28.06; root --web -e 'new TBrowser'"

On Mac

• Install Firefox (or Google Chrome), the script does not support Safari yet
• Set Firefox as your default browser (in System Preferences -> General -> Default Web Browser: Firefox)
• Copy the rootssh script from this location: https://raw.githubusercontent.com/root-project/root/master/config/rootssh to any local folder on your Mac
• Open a Mac terminal and cd to the location of the rootssh file that you just downloaded

$ cd /path/to/rootssh/folder

• Make this script executable and run it, with following commands:

$ chmod u+x rootssh
$ ./rootssh username@raad2

• This will open an ssh session on your Raad2 account, with the proper settings
• Enter your Raad2 account password
• Issue the following commands:

username@raad2:~> module load root/6.28.06
username@raad2:~> root --web
root[1] TBrowser tb

• If everything went well, a Firefox window will open up on your Mac, inside this window you can navigate to the file.root that you want to browse
