So that we can use both Guralps for Adaptive stuff, and so that I can look at the differential ground motion spectra, I've reconnected the Guralp Seismometers to the PEM ADCU, instead of where they've been sitting for a while connected to the ASS ADC.  I redid the ASS.mdl file, so that the PEM and PEMIIR matricies know where to look for the Gur2 data.  I followed the 'make ass' procedure in the wiki.  The spectra of the Gur1 and Gur2 seismometers look pretty much the same, so everything should be all good.

There's a problem with DataViewer though:  After selecting signals to plot, whenever I hit the "Start" button for the realtime plots, DataViewer closes abruptly. 

When I open dataviewer in terminal, I get the following output:

Does anyone have any inspiration for why this is, or what the story is?  I have GR class, but I'll try to follow up later this afternoon.
