Tom, Thanks for the info. I could see a reimplementation as a good project for some CS undergrads here at GT. Is there a particular way the QT time raster should be rewritten (e.g. using particular libraries, QT versions, etc) to be OS X compatible and align with the future direction of QT plots in GR? Or is the issue more complicated than just a port/reimplementation? I personally find the raster extremely useful for analysis.
