David - I'm running Ubuntu 10.04, ROS 1.1.13-12 (installed through

Last Changed Author: dfseifer

Here is the bagfile that I just recorded: www.rbedi.net/2010-07-22-11-29-38.bag
William - I didn't set anything up for my transforms -- I just set ROS
to record the /tf topic -- is there any setting up I need to do?
Thanks for all your help,
Rishi
