coverplot does not work with Q8 data

Plotting a sync file generated by msi from Q8 data gives this error.

Traceback (most recent call last):

I am working on creating a stationxml file with nexus, but I haven't had much success. I will update this issue once I am able to test coverplot on a stationxml file.
