What steps will reproduce the problem?
1. Collect data using location probe with the same location. (keep the phone on 
the same place for couple of minutes)
2. Use the funf_analyze.py to visualize

Following error is reported

Thanks, I was running into this too. I pushed your fix into my repo where I 
fixed the issue that a SimpleLocationProbe was not used by funf_analyze.py:
