RTXI v1.2 now has a COMMENT type for Workspaces that also works for DefaultGUIModel. RTXI v1.2 is currently only available as the latest SVN code from our Sourceforge site. It is NOT the version of RTXI on the Live CDs. The DefaultGUIModel is described in this tutorial. While a PARAMETER can be a double or integer datatype, a COMMENT is a string datatype. Comments will be recorded by the RTXI Data Recorder, but unlike PARAMETERS should not be accessed in real-time. This capability will allow users to save text alongside their real-time data for creating user logs. To update to the latest version of RTXI, grab the source code from the Sourceforge SVN repository. In the directory where you would like to keep RTXI, eg. /home/USER or /opt (it does not have to be where you store your own model files):

$ svn co https://rtxi.svn.sourceforge.net/svnroot/rtxi/trunk rtxi

If you do not have subversion and you are using Ubuntu:

$ sudo apt-get install subversion

Inside the /rtxi directory:

$ sudo ./autogen.sh
$ sudo ./configure
$ sudo make
$ sudo make install
