Root Browser

Tuesday, February 2nd, 2010

When I run “TBrowser b”, it opens up TRootBrowserLite and gives me this message:

“You are using the old ROOT browser! A new version is available. To use it:
Select the ‘New Browser’ entry from the ‘File’ menu in the browser, or change
‘Browser.Name:’ from ‘TRootBrowserLite’ to ‘TRootBrowser’ in system.rootrc”

However, I changed “TRootBrowserLite” to “TRootBrowser”, but I then had a Break-gdb not found type of error. Anybody know what’s up with this?

Thanks,

Michael

Logging into lxplus

Tuesday, February 2nd, 2010

I was running the standard checks that Arno gave us to make sure everything is up and running on my computer. I discovered that I couldn’t run “xterm” while connected to lxplus.cern.ch I received the error “xterm Xt error: Can’t open display:”

Thanks to some help from Elim, I found out I was connected via “ssh user@lxplus.cern.ch” whereas I needed to be connected to “ssh -X user@lxplus.cern.ch”. Sure enough, I connected to ssh -X and was able to run “xterm” without a problem.

If you’re having problems with running “xterm”, try this out and see if it works.

How to check you ROOT installation

Tuesday, February 2nd, 2010

To check if your ROOT installation is OK you could type into the ROOT window the following:

TBrowser b;

If an additional window would open up most likely all is OK.

Cyberduck

Monday, February 1st, 2010

For all Mac users,

Take a moment to check out the Cyberduck application at http://cyberduck.ch/ to make things a little more convenient with server connections and directories.

It is also recommended that you use this in conjunction with Aquamacs at http://aquamacs.org/.
